I am the lucky owner of the Knight 670 capicaitor tester ,vintage ,it was restored by Buddy ,who does amazing work ,I like testing the bigger capciators at voltage of the caps ,testing the caps at actual voltage is better it and it will check for leaks and many other test you can't get from modern digital tester I have those too ,I have four inexpensive ear testers,and a fluke ,I like the ones you are showing us too.thanks for shareing
@@charlesklein7232I was giving Nanova Lab a chance to share first in case he had a video to share with us. This video is one about the Manfred circuit. Hope it helps! th-cam.com/video/MRWwlTdAPn4/w-d-xo.html
Good comparison. The ESR measurement, apparently, should be done at 100KHz, but at that frequency it is not possible to read the capacitance correctly, for this 100Hz is recommended; hence the limitations of the MESR100 and the errors of the modular meter. The BK model applies a signal of more than 0.6Vpp, which makes it inappropriate for "In circuit" readings. BK has a specific ESR meter mod BK 881, which can make in-circuit measurements, but it is as expensive or more than the PEAK. And one last consideration; almost any multimeter can read the capacitance of a capacitor quite well; another thing is to measure the ESR.
I had Probe Master make 8"-12" custom leads for all my ESR meters. The quality is amazing... I ordered 3 custom sets and different tips for under $100..
That's a lot of cash to spend on leads IMO. Why not just make your own with any old set of leads by trimming them down and soldering on whatever contacts you want to use? Just for convenience purposes?
Hi, Thanks for the video. I have several Capacitance meters but I do like the Peak model. The Peak ESR70 also uses the 12v battery. One thing none of these meters do is check for Leakage on the higher voltage caps. I think you had a polarity issue on a couple of the tests but that is an easy mistake to make while making a video. I'm sure you know what your are doing under normal conditions. Oh and yes the audio is low but I cranked my audio to max and was able to hear Ok then. Thanks again.
I had the Peak and the BK Precision and sent them back for the DE-5000. That was a great choice as it's better than anything in the video in my opinion. Definitely a great video nonetheless!
Good comparative tests but: ESR70 is way way too expensive for what it does (they officially say that the capacity reading is just informative reading and that it is not accurate) so what is left really is just the ESR reading and just for that function is....well simply not worth buying. I would say that if you are serious about electronics BK is the tool to go for. However, to be absolutely sure of a capacitor you will need another piece of equipment (not many people are aware of) is a capacitor leakage tester. I have encountered caps that have reasonable ESR reading and capacitance is within tolerance but when tested but failed the leakage test. Its an important test
The main feature of the version 2 is the in circuit testing. meaning you don't need to remove the component from the circuit board, there's another mesr -100 meter that is blue in colour and looks exactly the same that one dos capacitance and esr reading its a 2 in one meter , but this one the mesr-100 V2 dos the in circuit test , and the other one dos not . that is the difference , so i think you can make better use of this one better because of the in circuit test. not many esr meters ar capable to carry out in circuit testing. i think you are getting confused thinking that the other one is better because its telling you the capacitance but if you are working on a faulty PCB than you only need to know the esr and not the capacitance as the capacitance would be be printed on the component/ capacitor that you are working on . and you dont have to desolder any thing to check it. i hope you understand now. for the is circuit test to work the meter has to operate with a sine wave of 100 kilohertz test.
Honestly sine imho is a bit sick idea bcos in mostly voltage pulse regulators doesn't work on the sine. This signal looks like 2 step stairs rectangular and exactly rectangular signal is the most closelly of the truth, real work of caps. Here this caps work in dangeros, and here his esr is much much important. In many circuits where the caps work for filtering only the power his esr it's not so so important, and can be work over years and years. Also meassure in circuit its not allways possible, often can be falsed by the connected circuit frankly speaking.
For your information your metre is Version 2.0 and not version 1, read the manual you see, you are mistaken. V2 stands for version , it even tells you on the box if you look. look for MESR-100 v2. version 2 operates with a sine wave and not a square wave , page 2 in the manual will confirm that. I still gave you a thumbs up because you sound like a good man
I still gave you a thumbs up because you sound like a good man, also if you look at the meter on it it says in circuit testing, Version one dos not say that.
Great tutorial. You can also test the resistance and microhenries of the inductors with the esr meter. The reactance formula is 2𝛑FL. That would be 2 x Pi x frequency of esr meter x 100 (uH) Just plug it in. R=0.628 X L(uH) L(uH)=R(ohms)/0.628
my atlas esr70 olus measures some capacitors with an esr of 0 and also some with a very low esr but up to 2-3 times its marked capacitance. I assume these caps are leaky and replace them. Not sure if this is accurate or not but I do notice that all brand new capacitors test within their marked value +- their stamped tolerance so I know the meter is working.
Dear Thrifty Tool Shed, question, please. Regarding the Peak ESR+ Meter: ¿is it safe to 'power on' this meter on with the leads connected to a passive discharged capacitor, or a resistor, please? You do this with a charged cap even, and seemingly without any issues. (The reason I ask is that the manual says: "To allow the self protection mechanism to function, always ensure that the Atlas ESR has completed any analysis before connecting the test probes to a component"). ¿Do they mean powering it up (turning it on) with leads attached to component under test? Just wondering. (I own one of these fine instruments and am very worried about damaging it [big deal for me just purchasing one]). Any comments most welcomed. Thank you for making and posting this fine video.
Hi, thanks for your kind comment! I believe I understand your question. Yes- I would always make sure the meter is powered and self test complete and ready before connecting to ensure the leads to a cap. I also would make sure no dangerous potential is on the terminals of the cap. I don't think the atlas meter will discharge anything safely but a low residual voltage and of course no powered circuit can be tested. I always try my best to have already discharged a cap before the leads are connected and the meter ready to test. Hope this helps.
@@ThriftyToolShed Dear sir, thank you for the kindness of a reply and all the recommendations, cautions, and advice. I appreciate it. God[Bible] Bless.
Great video, I'm looking for a cheap one, to work on my old tube amp, & a 70s receiver I want to restore, just personal things, amp needs recapping have one grey cap like the one in your video, ,have a cheap Fluke coming in the mail, my Radio Shack meter won't measure ohms anymore so I ordered that, & now looking at the cheap ESR meters on ebay. This was very informative. I hear some things don't ship with instructions. I learned a lot, thanks
I have a knight kg 670 I think I would trust more it shows leakage and much more ,I have some of the one you show there ,but you can't put 450 volts to them if needed and they don't show leakage .but those are pretty good .
What if you want to measure a capacitor that falls outside the given ESR table? For example, I have a 400volt 80 Farad capacitor in circuit. How would I test that one to make sure it is good using the MESR-100? Or, can it be done at all using this meter?
Oops OL on my meters is Open Line , I could be wrong though....... When I redo a radio or power supply I usually recap the unit. I never test them. I replace all of them with high end caps... That's just me though......
You got me, and sometimes open loop. After working in the industrial side for over 25 years , when I am talking and see OL who knows if I'll blurt out over load, open line or open loop lol! I agree on the recapping for sure. It's hard to justify on some repairs, but drives and other expensive industrial devices, it is the only way to do it!
"The capacitor was initially known as a condenser. The term “condenser” was associated with it because it was supposed to condense electric charge. The charge it could hold at a rated voltage was known as “capacity.” This term was in use till about 1960s". I like this information from BYJUS.COM byjus.com/jee-questions/why-capacitor-is-called-condenser/
I have had similar issues in circuit. It will usually read bad or at least weird with one or more in circuit giving issues. I usually have to take one side of at least one of the caps aloose to try to narrow it down to the bad component.
Thanks for the video! Do you know if the MESR-100 V2 is able to measure ESR in a 12.000uF 100V capacitor? (I see the chart on the bottom of the meter maxes out at 10.000uF 35V)
I have not measured one to say for sure but since it uses 100KHZ to measure actual series resistance, it should measure just fine even if the chart does not show that high. I just get the ESR rating from the data sheet of the cap if available and compare to the reading! Hope it helps!
Yes you can! I have been using the Atlas ESR70 in circuit for years. It has the 100kHz measurement frequency. The GM328 is the very first video that I posted! Link in description. th-cam.com/video/8Jt4YdTBMrk/w-d-xo.html
This is link to my very first TH-cam video. The quality is not great, in the comments is also a manual for the GM328 that was kindly given in a comment a while back!
James Rockford, I would use the Peak ESR70 most likely, but also I have always had luck with hvac caps (5-80uf) with the newer flukes. The 87V and the 179 both measure the capacitance well up to 9,999uf. But only some of the newer ones, the older (87III for example) did not read high capacitance at all (mostly for Electronics use) For Hvac checks that’s really handy to use one meter that does a lot. But having the Peak ESR 70 around will always be handy as well. Hope this helps and thank you for your comment.
Yes, and best to go by the actual manufacturers data sheet as mentioned. The general charts most of the time help in pass or fail unless in a very high frequency circuit design.
There is a chart with the Mesr-100. The one I printed is from internet search I just pulled one up from QuantumWarp.com that looks like the typical one I print out. Hope it helps!
I have the 898 D rework,station I paid 47.00 ,where your web site you posted the blower only for more then my 898D has both a soldering station.and the heat blower for smd componets,but eBay was cheaper and You get more,Amazon always pricery.,I love mine 898D ,it does it all, I have just also bought the Hakko fx 888D hope to use it soon..
I just bought one of these devices the one with the green screen and the large chip in front the one at 26.5 minutes . I have checked a couple of capacitors and I keep getting esr=.00 ohms C is 917 battery is 9.4 volts vlos is 1.1% I have watched other video with these devices and there is always an ESR value greater than 0. I actually had them send me a new one and it is doing the same thing. What would you suggest?
Mark Lawless, Mine is most likely an older revision but on smaller caps it will not show the esr value it has to be a larger electrolytic cap to show the esr value. I do not remember right off about the value it switches over but if you try a rather large cap it should be showing esr!
@@ThriftyToolShed I played around with it more and found that if I put the capacitor along the contacts on the pad it would give me an ESR reading. Also are you aware that the unit has other features if you press and hold the button you can go into different functions.
Mark Lawless, yes, actually, my first video I decided to do was on the GM328 and it did pretty well even though the quality was terrible. I think people liked it because I did go as far as showing the menu and contrast adjustment etc. Sounds like you are having loose/bad connection at your zif socket, but it's weird that two have done the same thing.
@@ThriftyToolShed Well as it turned out I found that I did need to do a calibration after doing that then it was working much better. Thanks for your help.
Mark Lawless, awesome, I did mention the calibration procedure in my first video, but never really thought it needed typicalky unless you add leads(resistance) to the testing, but that is good to know. It is strange you had 2 do the same thing! Happy testing!
Need to test a cheap Chinesium 50V 50K uF capacitor. What methods are there to test this POS before I use it in my cheap MIG welder? Also adding a full bridge rectifier to steady the AC and get less splattering when I weld. Cheers
The Peak ESR70 is still one of my favorites since it's easy and being audible you can go through the board checking with out having to keep looking back and forth at the display, it's really the quickest and aslo shows the capacitance as well as the ESR. The Mesr-100 is still good for the money as well. amzn.to/3CqvEgM The mesr-100 is cheaper, but doesn't show the capacitance. amzn.to/3EvOULE
Hi, I have a link in the video description but it seems to be out of stock. When I search GM328 other manufacturers show up, but I guess the Yosoo is now showing out! It was in stock, I don't know how long it will be.
The Tool Shed doesnt seem that thrifty with nice equipment like BK Precision, Oscopes etc. The audio however, that was a little thrifty. I have my eye out for a deal or sale on a BK 879 or Keysight LCR meter.
Kevin Gittemeier, I wish you luck on the deal finding. I guess I was shooting for how even the cheaper capacitor ESR meters are work well in comparison for the thrifty! Lol. Sorry the audio is poor. Thanks for your feedback!
Audio is perfect on my pc (via amp tho). Thifty probably knows this, but just in case there should be a 'normalise' function in your video/audio software that gains up the volume... if that indeed is the issue.
old video but here's my opinion, capacitors needs to be tested several ways, open/short/capacitance/ESR/Leakage/Life Span, and not one single tester can do this testing of this device with accuracy and consistently, for the hobbyist like me we need a reviews of this tester which is which best bang for the buck, but i would say i have an eico bridge resistor/capacitor leakage tester and it was old tube tester that give me accurate and consistent measurement but not esr, although power factor testing is there, just my 2-cents. also some of the meter you reviewed is not as "thrifty" as your you tube name/title indicates, they're quite expensive, the atlas and b&k, thanks from toronto....................
Very true. This early video did have a learning curve, including volume level! My goal was to show how well the cheaper meters did for the hobbist like you and me against the higher cost items! I wanted to leave it to the viewers to decide but I did think the cheaper meters did well. And I absolutely agree about the many ways a capacitor should be checked. ESR was just one of the ways and important for higher frequency devices and up until about 3 years ago I did not have a way to check it. Thanks for your comments!
I have been trying to speed up videos ever since this one. I did get alot of feedback on the length of it. I had changed alot in the last 4 years or so. Hard balance between too much information and then sometimes getting hundreds of comments asking why something wasn't explained. It's harder than I previously imagined. Thanks for your feedback.

Hi, The one I have is the ver2. I stated in video I had ver1. But the instructions stated V1.0 But believe it or not that was the manual version, I realized later that I had the ver2 due to the 100khz and the USB port on the side! Sorry for the confusion, most I see available now is in fact the Ver2 I believe!
It's from the Peak Atlas ESR tester manual IIRC, but you can find all sorts of charts on google images by searching "electrolytic capacitor ESR chart".

Yes, that older video was low. TH-cam will not allow me to change it after upload. It is over 5 years old so I would just have to delete it. No way to edit unfortunately. I think the last few years have been much better. All about learning, thanks for your comment!

This is link to my very first TH-cam video. The quality is not great, in the comments is also a manual for the GM328 that was kindly given in a comment a while back!

@@ThriftyToolShed thank you very much,enjoyed your video very much.
Which meter or meters would be used for HVAC caps. Thanks and great job of explaining.
James Rockford, I would use the Peak ESR70 most likely, but also I have always had luck with hvac caps (5-80uf) with the newer flukes. The 87V and the 179 both measure the capacitance well up to 9,999uf. But only some of the newer ones, the older (87III for example) did not read high capacitance at all (mostly for Electronics use) For Hvac checks that’s really handy to use one meter that does a lot. But having the Peak ESR 70 around will always be handy as well. Hope this helps and thank you for your comment.
Thanks for the tip.
I sorry to say that I have 3 different ESR meters and all 3 have different reference charts since they work with different frequencies
Yes, and best to go by the actual manufacturers data sheet as mentioned. The general charts most of the time help in pass or fail unless in a very high frequency circuit design.
Why SMD capacitor with pico not including?
Well there are a few Electrolytic caps that are SMD, but most are ceramic. I focussed on ESR due to the video title as such.
That PCB type meter showing correct or acceptable values?
There is a chart with the Mesr-100. The one I printed is from internet search I just pulled one up from QuantumWarp.com that looks like the typical one I print out. Hope it helps!
I have the 898 D rework,station I paid 47.00 ,where your web site you posted the blower only for more then my 898D has both a soldering station.and the heat blower for smd componets,but eBay was cheaper and You get more,Amazon always pricery.,I love mine 898D ,it does it all, I have just also bought the Hakko fx 888D hope to use it soon..
I just bought one of these devices the one with the green screen and the large chip in front the one at 26.5 minutes . I have checked a couple of capacitors and I keep getting esr=.00 ohms C is 917 battery is 9.4 volts vlos is 1.1% I have watched other video with these devices and there is always an ESR value greater than 0. I actually had them send me a new one and it is doing the same thing. What would you suggest?
Mark Lawless, Mine is most likely an older revision but on smaller caps it will not show the esr value it has to be a larger electrolytic cap to show the esr value. I do not remember right off about the value it switches over but if you try a rather large cap it should be showing esr!
@@ThriftyToolShed I played around with it more and found that if I put the capacitor along the contacts on the pad it would give me an ESR reading. Also are you aware that the unit has other features if you press and hold the button you can go into different functions.
Mark Lawless, yes, actually, my first video I decided to do was on the GM328 and it did pretty well even though the quality was terrible. I think people liked it because I did go as far as showing the menu and contrast adjustment etc. Sounds like you are having loose/bad connection at your zif socket, but it's weird that two have done the same thing.
@@ThriftyToolShed Well as it turned out I found that I did need to do a calibration after doing that then it was working much better. Thanks for your help.
Mark Lawless, awesome, I did mention the calibration procedure in my first video, but never really thought it needed typicalky unless you add leads(resistance) to the testing, but that is good to know. It is strange you had 2 do the same thing! Happy testing!
can you provide a PDF for that chart please
It's been a while ago...
I think this is the one I printed and have up for my workbench?

Need to test a cheap Chinesium 50V 50K uF capacitor. What methods are there to test this POS before I use it in my cheap MIG welder? Also adding a full bridge rectifier to steady the AC and get less splattering when I weld.
Cheers
any recommendation for an in circuit cap tester??? in yr 2021
The Peak ESR70 is still one of my favorites since it's easy and being audible you can go through the board checking with out having to keep looking back and forth at the display, it's really the quickest and aslo shows the capacitance as well as the ESR. The Mesr-100 is still good for the money as well.

The mesr-100 is cheaper, but doesn't show the capacitance.

Where to find the Yosoo GM328 ? Thanks.
Hi,
I have a link in the video description but it seems to be out of stock. When I search GM328 other manufacturers show up, but I guess the Yosoo is now showing out! It was in stock, I don't know how long it will be.
The Tool Shed doesnt seem that thrifty with nice equipment like BK Precision, Oscopes etc.
The audio however, that was a little thrifty.
I have my eye out for a deal or sale on a BK 879 or Keysight LCR meter.
Kevin Gittemeier, I wish you luck on the deal finding. I guess I was shooting for how even the cheaper capacitor ESR meters are work well in comparison for the thrifty! Lol. Sorry the audio is poor.
Thanks for your feedback!
I have videos with much worse audio.
Audio is perfect on my pc (via amp tho). Thifty probably knows this, but just in case there should be a 'normalise' function in your video/audio software that gains up the volume... if that indeed is the issue.
does your esr70 also gives false positives?
It is very rare. It is usually one of the best quick testers for a go to.
old video but here's my opinion, capacitors needs to be tested several ways, open/short/capacitance/ESR/Leakage/Life Span, and not one single tester can do this testing
of this device with accuracy and consistently, for the hobbyist like me we need a reviews of this tester which is which best bang for the buck, but i would say i have an eico bridge resistor/capacitor leakage tester and it was old tube tester that give me accurate and consistent measurement but not esr, although power factor testing is there, just my 2-cents. also some of the meter you reviewed is not as "thrifty" as your you tube name/title indicates, they're quite expensive, the atlas and b&k, thanks from toronto....................
Very true. This early video did have a learning curve, including volume level! My goal was to show how well the cheaper meters did for the hobbist like you and me against the higher cost items! I wanted to leave it to the viewers to decide but I did think the cheaper meters did well. And I absolutely agree about the many ways a capacitor should be checked. ESR was just one of the ways and important for higher frequency devices and up until about 3 years ago I did not have a way to check it.
Thanks for your comments!
Where did you find that chart at I want to download it .
I searched for ESR values chart and several similar came up. I may have used the one from quantumwarp.com?
la parte sulla scarica dei condensatori mi sembra troppo lunga, esageratamente lunga.
Esr table?
Good vid.... Even better if you set playback speed to 2...
Thanks for your comment!
I have been trying to speed up videos ever since this one. I did get alot of feedback on the length of it. I had changed alot in the last 4 years or so. Hard balance between too much information and then sometimes getting hundreds of comments asking why something wasn't explained. It's harder than I previously imagined. Thanks for your feedback.
@@ThriftyToolShed I feel ya... I use the playback speed to make lots of vids suit my needs... Not just yours... I do like your thoroughness.. I like a fast pace... I'd imagine a new member if the electronic community will really appreciate the slower pace... Please keep them coming... Love to see repair vids... PWM!!!
@@ThriftyToolShed... Thanks for the video!!!
No Anatek ESR meter? :(
Always room on the bench for another. Did not have one but still may have one day!
Where did you see the version 2 out at I cant find it.
Hi,
The one I have is the ver2. I stated in video I had ver1. But the instructions stated V1.0 But believe it or not that was the manual version, I realized later that I had the ver2 due to the 100khz and the USB port on the side! Sorry for the confusion, most I see available now is in fact the Ver2 I believe!
Look on ebay or Amazon... Just bought mine on Amazon, version 2 is in the description, meter works awsome. Also very good at reading low resistance...
@@airgliderz thanks
Nice video
Muhammad Yawar Ifraheem , Thanks for your comment!
Where did you find the chart?
It's from the Peak Atlas ESR tester manual IIRC, but you can find all sorts of charts on google images by searching "electrolytic capacitor ESR chart".

Use the word 'However'
however, you can find all sorts of charts ....
NOT but you can find all sorts of charts on ....
BUT denotes a 'negative aspect' to something, something in contrast or unexpected.
@@andrew_koala2974 Wow, thanks for the lesson Mr K!
I use tc1 for that.
Bob-72 Zob ima , The tc-1 looks really neat. I do want to try one!
Looks similar to the gm328 but with color display and housing!
Yes, I advise you. It detects almost everything (LED, diode, transistor, ...). Still weak point, it does not detect very weak capacitors.
MESR unit has no reference for 2200 uF, WTF ???
If this was a performance to cost review and survey, 10 minutes would have been sufficient. All I got out of this video is a comparison of apples, oranges, pears, and grapefruits.
Well thanks for using your valuable time for the rant!
I can hardly hear this.
Rob H, thanks for your feedback.
Thrifty Tool Shed: You're welcome.
Get a hearing test.
Volume was super low.
When you upload a video to TH-cam, it will sometimes drop the audio from what I heard. That said the low volume was an easy fix for me. Wait for it. I turned the volume up. Heard everything he said. If there was any struggle, it was with his accent. Live long and prosper.
Sound is very very low
-20 DB audio could watch cuz I couldn't hear
Yes, that older video was low. TH-cam will not allow me to change it after upload. It is over 5 years old so I would just have to delete it. No way to edit unfortunately. I think the last few years have been much better. All about learning, thanks for your comment!
Dude, crank up da volume. Crank up the volume.
It's a 3 year old video. I have of course increased the volume on my videos as well as better microphone since. Thanks for your comment.
you are boring me right now 28:08
FOCUS
Man WHAT THE HELL HAPPENS WITH YOUR AUDIO? My volume is at 100 and I can barely make out your words!!!!
I bought a microphone right after this video. Thanks for your comment!
BAD AUDIO REDO THIS VIDEO AUDIO VOLUME IS TO LOW.
"I WILL GIVE FULL REFUND!"
Videos too long, and audios too quiet
I have changed my videos alot in 3 years. If I could change it now I would.
