i would say the 4 or 6 test leads for injector testing would be my no# 1 choice. having the info to test 3 or 6 injectors/ignition at the same time can be a real help for Dianostic troubleshooting. but i am sure the pack of leads you were showing can also come in handy at times. keep it tuned and go like hell!
Just received my first order from RotKee and I am well impressed with the workmanship and quality of the probes. For the money they are excellent value. I am looking forward to using them in my every day mobile diagnostic work. Excellent video. Keep up the good work.
Awesome! Hope they serve you well 👍
@@MechanicMindset Just putting together another order having watched some more of your videos and also looked at some of my leads which are not up to standard from other suppliers. 🙂
Solid company. Especially for probes. Fellas go and sign up to Mechanic Mindset. Love the training
What probes you got D?
yes, Darren's a Legend 😇
Cool video mate, thank you!
Thanks a lot, Darren. Useful information and excellent presentation, as usual.
Cheers. George
Cheers George! Have you seen Rotkee before?
Yes I have seen their site in connection with the waveforms available on it and I was wondering about their equipment too. Now recommendation coming from you makes me want to buy some 😊. Let's see.
I was looking for more affordable pressure sensors for in cylinder diagnostics. Are the ones ROTKEE offer going to work? That would be nice to know.
@@georgetzekov445 I’ve not tried their pressure sensors but they seem to have a BNC output so I would say yes.
You would just need the parameters to make the custom probe.
I assume it would come with its own separate power supply too.
One of the pressure sensors looks like it’s out of stock at the minute
thanks for this!
I have been using their products for quite some time and can confirm that they ARE well made, I've had zero problems and haven't really been all that nice to them... Their back probes are really nice, I thought the springy part would give up but no sir, they're unkillable.
The only problem is that they don't make every little thing one might need, I would really love to have that level of quality at those price levels for piercing probes, connectors, adapters aso.
Thanks for sharing, hopefully they get your feedback 👍
Looks like you're getting pretty comfortable with your scope, and you're at almost 20k subs. Your video and audio quality is awesome.
I finally got a Rigol MSO5000 a couple of months back, instead of the Micsig I was looking at, but I've got a ton to learn about using it. Naturally, Rigol lowered the price on all their 4 channel scopes by $200 recently, plus they're still including the bundled serial decoders and signal generators. I'm guessing a new scope is about to come out and full obsolete mine. ;)
Speaking of Micsig, they have a new automotive tablet scope with knobs, as well as touchscreen. It looks pretty handy, being so portable and all.
Thanks! We try and move on and up. Also got our own place now!
I’m sure the scope will be fine. I’m using g an old Pico 4423 in this video. 10 years plus! And still performing well.
I had a little go with a MicSig. Didn’t get to know it too well. One issue I found was the screen was difficult to see outside
nice going to get some of them leads can be real helpful ,testing and Dianostic troubleshooting.
Awesome! Which one is your favourite?
Darren thanks for sharing and I’m going to do some ordering today. Darren a quick idea you could include in one I’d our classes is converting the voltage settings on amp clamps to reading amps to create custom probes on pico. I’m sure it would help others in our group. Now on to ordering. 👍
Let us know how you get on Artie.
I’m sure we have a section on customs probes already. Try this mate:

@@MechanicMindset thanks Darren
I've had my eye on Rokee for a while now. Fairly recently I've started seeing others talk about them. I was planning on placing an order a while back and then everything happen with Russia, so they stopped shipping. I've had some other priorities since they started shipping again. I appreciate you doing a video on their leads. They looked great, you just don't know sometimes. I'll have to take another look at their products soon.
They have certainly fell on tough times. All good feedback from anyone who bought so far 👍
@@MechanicMindset is that company based in the region of Ukraine ? or the U.S.A ?
@@sollykhan2385 Ukraine
The 4 in 1 or the 6 i 1 would be a nice addition. I actually never look if they pull to ground. Maybe never had any failure where this was a main cause. Good pricing for these products.
They are a real creative way to test 👍
Hello and thank you very much for the demonstration, in addition we can pay with paypal
Ah yes, I see this is an option now. Thanks for sharing 👍
Nice video
Love rotkee. Been using there stuff for a year
Cool! Which probe are you using the most?
@@MechanicMindset the pressure transducer. Very accurate for in cylinder
on rotkee website the lx1 coil on probe says that the output range voltage is over -1v to 1v, but you got peaks almost over 20v, should i be using a attenuator on my pico 2204a????? or there is something im missing?
Great conttent! im getting the osciloscope master course as soon as i can! following from mexico
The Rotkee probes look interesting. I have similar probes from some other vendors, but I like to try new probes. I ordered several, the acoustical probe, the 4-in-1 probe (2), and TL-mlp Multipurpose Test Lead. I enjoy watching your videos. I do have a PicoScope, a 2204, for small stuff - and mostly to be able to say I have a PicoScope for folks that may pooh pooh me having a non-PicoScope in my arsenal. My GoTo scope is a MicSig 4 channel SATO1004. It is very capable and not needing an outside piece of equipment (laptop) makes it easier to use - less clumsy. All of the various demonstrations you present can be performed with the MicSig unit also, which is nice.
MicSig is a nice scope! Very convenient as a tablet 👍
@@MechanicMindset I like both, but the MicSig is my Go To scope.
This may not be "new" to you, in fact I am betting it isn't, but for for giggles I will share a few thoughts. I recently became aware of, and purchased two Chassis Ear kits. One has wireless sensor, the other had wired sensors. For the wired sensors they are terminated with 3.5mm sound jacks, which get plugged into a 6 channel box where I can flip a knob to select which channel (sensor) i want to listen to. The idea is to find out which sensor is picking up a bothersome noise or vibration.
Well, while I was tinkering with the wired sensor kit I decided that I wanted to pick up some 3.5mm jack socket to BNC socket adapter cables. Then I can plug in up to 4 wired sensors and direct the electrical signal from the sensors into each of the 4 channels on the scope. That way I can get a visual representation of the various sounds. I can also watch up to 4 channels simultaneously as opposed to only being able to listen to one channel at a time. Morever, were I to pick up a low cost 8 channel recorder/playback machine I can make a recording of multiple different sensors that I can play back at any time I like.
I found out, after my epiphany, that Pico has an NHV kit already, that does what I am describing. But, they have taken their design to a true cutting edge, whereas my approach is more akin to a hacker coming across a cool idea. I guess I have a poor man's Pico NHV near equivalent for a lot less than the Pico kit is. Now that I have these Chassis Ear units I can't am hardly wait to come across someone with an objectionable noise! So, I will just begun to play with the Chassis Ear morphing into the oscilloscope arena and see else I can come up with. I have lots of ideas already. What fun, blending two or more technologies to help resolve an issue that drives a lot of folks crazy.
@@gilberthale7777 I love the chassis ears kit; used it all the time!
Yes they give off a small voltage; I think they are piezo elements which are often used in microphones. The Pico kit is next level; I understand they are more like accelerometers which don’t suffer the same physical effects of piezo and can measure more 👍
@@MechanicMindset chassis ears do use piezo chips to generate low voltage signals. Just having the chassis war kits is awesome unto itself. But melding into the scope world is going to make it all the more fun.
The Pico NHV kit is definitely awesome. And way over the top. From what I can tell been without a scope interface the chassis ears are going to be a game changer for me. I wish we had these available back in the 70s and 80s when I worked as a tech.
@@gilberthale7777 Cool! Yes the NVH kit can determine the frequency of vibrations and noises which can then be paired with components of varying rotational speeds (so you can tell between diff, wheels, engine, transmission etc)
Well that was interesting. I'm ordering the 2204A and these leads are a great way to compare my 4 injectors using a 2 input scope. Just need to use the attenuators and figure out the ground configuration. Is this a correct assessment? Your videos are fantastic!!! Thank you!!!!!
Great little set up. All you need to do is connect one of the other channels negative lead to ground 👍 cheers!
Would you be able to test the shielding ability on the Rotkee extension wires with the translucent insulation like that are on the end of the mixer lead compared to a traditional cable like the Hantek HT30a? I was looking at these but have some reservations about how well this type of wire would do to prevent interference.
I think there will only be a minor change. Did you see the video where I made my own scope cable with twisted speaker cable?😆 It worked ok.
Their software looks pretty impressive, and for the price will be best scope of or the money.i wonder how it does with can bus.
I would love to see a review of their oscilloscope I enjoy using mine but there's a lot of features that I'm still unsure of
I think some parts are still in development like math channels. The scripts are really interesting. I don’t think it’s available at the minute; I have one and I’ve had a play, it seems to be a very capable oscilloscope. When they’re back on sale I’ll look at doing the video 👍
I heard about ROTKEE a few years ago, I got there petrol in cylinder pressure sensor and adaptors I have found it to be very good quality, I like the 4 into 1 lead, the only problem I had when I ordered my parts where paying for them bit off a messing about lucky I knew someone in Ukraine who paid locally for me, ROTKEE also have a good waveform library where you can upload waveforms from any oscilloscope unlike Pico.
Thanks for sharing!
@@MechanicMindset Just ordered a few more items from ROTKEE and they now use PayPal which make paying much easier.
@@no1conrod Agreed! I think the payment terms were a sticking point for most orders 👍 Enjoy!
I had to use Wise, or some money transfer app like that, which was quite difficult. But Rotkee are all good.
The signal is between 5V-15V for the Rotkee Ignition Pickup. Igniton is usually around 50V, is there a conversion needed to get actual measurement or is it for waveform shape analysis, not waveform measurement?
Thats right, shape analysis. It may vary depending on coil construction. And as far as I’m aware we can only ‘measure’ secondary kV on the HT lead to the plug 👍
Hello, can you explain, how to connect the 4 to 1 rottkee ignition probes to the Pico 4425A, espacaly how to ground it. Thanks
You’ll need a BNC splitter and connect the other side to a ground 👍 I got one and it works
I will be ordering the 4 into 1 leads and I was thinking about ordering two so I could cover 8 cylinders on two channels along with two of the basic 4 into 1 leads so on a four channel scope I could see all coils and all injectors on an 8 cylinder engine for example. As for a 6 cylinder use four on one channel and two on another channel. Is there something I'm missing or do you think that would work? Great video and I will be without a doubt be ordering from them. An $89 pressure transducer definitely caught my eye as opposed to $1300 for the Pico kit. Maybe you could do a comparison test with them possibly? Thank you for the great videos.
I did a video with the transducer. Works nice. Although WPS500 is another level; recently did a video in that too. For doin 8 cyl, you could get 2x 4-in-1 lead and feed them in to the same channel with a BNC splitter; as the waveforms won’t clash
@@MechanicMindset I actually found that video after leaving this comment. Thank you for the information on how to use two sets of leads on one channel. I will soon be signing up for your scope class. Thank you for all the great information in your videos.
Im trying to look for a decent cop probe that works with 3 and 4 wire coils since these are well insulated and cant pick up much with the ones ive seen. Thanks
These Rotkee ones are good. The Hantek one also has good reviews. I have the Pico probe and that’s pretty good too 👍
I'm confused on the mixer. So the first waveform on the screen is one cylinder, the second is another cylinder and so on?
Yes it captures 4 on one channel
Hola, donde se pueden adquirir las diferentes sondas? Gracias
Rotkee.com
I'm interested in the Rotkee LX6 inductive sensors but how would you keep all six attached at the same time?
Hey Tony, they supply a strong double sided tape to stick to the tops of the coils. I suppose you might be able to come up with your own securing method with a bit of creativity 😉
@@MechanicMindset Thank you 👍🏻. I guess I'm surprised that it would work through the double sided tape but I'll give her a whirl. Just received my Pico today, at 58 years old I haven't been this excited about about a new toy... uh TOOL in a long time. Thanks again for all of your content and your reply. Cheers!
@@Tony-rl2fr This video shows them in action. Enjoy the new toys! 😆

What kind of resistor is in the mixer leads, look to reuse my old mareli oscilloscope cable. !??
Oh, I did check a while back but can’t remember. It was relatively low
I was going to ask about backfeeding the other injectors with that four lead probe but you answered that. Wouldn’t putting a diode in-line be a better solution and not affect the signal while preventing one signal from actuating all injectors?
I’ve looked at this, I don’t think you would get a signal on the scope with diodes. It will stop the short circuit though. Draw it out, it makes sense then. At least that’s the conclusion I came to 👍
@@MechanicMindset I was thinking one diode on each leg of the splitter that would allow the signal to come up the line but stop signals from coming back down the line. I’ll have to draw it up and look at it. I’m pretty sure I’ve seen one with diodes for primary ignition in the past
@@Jpilgrim30 I’ll try and test it with 1 diode
Does the Rotkee pressure sensor or the COP inductive sensor require an attenuator on the Pico 2204a?
For the COP, possibly yes. Pulse sensor, no, it’s really low voltage 👍
Thanks for the reply! I decided to put in an order for both sensors as well as a set of their flexible backprobes.
Rotkee Lx4 Inductive Sensor can it work on PicoScope7 or you will need Rotkee MT Pro 4.1 Automotive Oscilloscope
It works, I have it 👍
Hi, friend. I don’t know what kind of oscilloscope you use, but I advise you to buy a postal oscilloscope 4
What's that, I've not seen before?
Would a diode be better than a resistor? It would block the voltage going back to the other injectors that aren't being fired. Do I make some kind o sense lol
Yeah, I can visualise that. Not sure how that would affect any negative readings, ie, when the voltage drops after the spike. Might give it a go with one channel and see what happens
i did electronics from an early age, the problem may be that Resistors will 'dissipate ' (absorb) a certain amount of energy (depending on the wattage) of the resistor, however with a Diode , there are an awful lot of different types, forward/reverse bias, Zenor types etc, is that it will allow current flow in 1 direction(or hold a certain amount of energy until it reaches a threshold) and then it has to do something with it? if you get my drift, remember the current flow will take the least resistive path, be it Earth, point of activity or dissipate in heat build up. but no harm in trying, were all wana be experimenters / home scientist's and students of learning,🙂
@@sollykhan2385 Yes, semiconductors are strange things!!
@@MechanicMindset indeed, current flow reminds me of the younger generation of today, it takes the path of least resistance !!🙂
potentially with a diode, if someone wanted to test a positive vs negative trigger ( or visa versa )....that could be problematic ?
This Rotkee Ukrainian company appear to be producing some very interesting products . Do you know if their VS vibration Sensor for use on diesel engines is compatible with the entry level Pico oscilloscopes ? They also do some very interesting equipment for detecting vibration in bearings.
It seems the VS Vibration Sensor is compatible; it has a BNC connector.
Yes, the NVH equipment looks interesting!
Great video , rotkee leads are good quality and value for money .. thanks Darren , check his mechanic mindset courses, great content and excellent value for money
Thanks
I've tried to order every single part that rotkee sells, unfortunately i wasn't able to figure out a way to pay :( i hope that'll change in the future as i really like what they're doing especially for the price
Good news, they recently started accepting PayPal!
@@MechanicMindset
First, many thanks to Darren's great tech videos, for which I really appropriate.
By the way PayPal says if the account is in Ukraine and private, my local PayPal won't send the money. If the account is out of Ukraine, I am allowed to send the money. I am from TAIWAN.
I too had problems with my first order but I used Wise money transfer that worked fine and I have just received my first order which I am very pleased with. When signing up for Wise send a photograph of yourself holding your driving licence or passport as I found there method problomatic. Cheers
Is the same using pico 2205A?
Yes 👍
I wish you would still use the 2204a that’s what I bought after your videos
Don’t worry mate, just mixing it up a bit 👍 more 2204a coming soon. Last video was 2204a 😉
@@MechanicMindset oh good you sold me I bought one now I gotta use it with your training
@@sheerwillsurvival2064 Great starting point for oscilloscopes. And the training will open up some cool features 😁
I received the parcel today sent by Rotkee, 45 days long to reach me. But they sent me too many the same test leads I didn't buy. They didn't send me the right products such as Pressure Transducer and so many others I ordered.
I was just about to see their web site but it is down. I don't know why???
The web site is back working now.
Sorry to hear that, hopefully they will respond soon
@@MechanicMindset Thanks, Darren.
I sent them 2 mails 3 days ago telling them about this issue. I understand they are having some kind of difficult time atm. I should wait for their response and hope they will read comments here.
About this issue, I still keep all of the products in that box as I have thought the parcel someone ordered might have been sent wrong to me.
I got a response from Rotkee today and he said he will sort out this issue for me. Many thanks !!!
Did you mean to say diode with the injector test leads?
No resistor. It wouldn’t work with a diode. I drew it up and can’t remember why, but it won’t work.. it still needs flow in 2 directions to take the measurement and operate at the same time
@@MechanicMindset Yeah, I trashed the idea not longer after I wrote it. I suppose the shape of the trace has more to do with understanding an issue than knowing an exact voltage value
@@howlinhog Yes I think it’s just more for checking that it’s actually happening
How long did it take for you to receive your package from Rotkee? I put in an order shipped to the US 6 weeks ago, and it still shows the same status on the Ukrposhta tracking as it did the first day they checked it in. I sent Rotkee an email a couple weeks ago inquiring about it and they just said that it was in transit, however, it doesn't appear to me it's ever left the post office in the Ukraine.
I’m sure it will arrive. I had a package arrive the other day but I don’t know when it was sent. I’ve not heard of anyone been let down yet. Hold tight 👍
They add resistors or diodes ?
Resistors I believe. Hence the ground voltage doesn’t go to 0V when the injector is activated. If you used normal diodes I don’t think it would work.
@@MechanicMindset but the resistors will consume the current in both way. Diodes will let the current to move in one direction.
I'm from chemical Engineering I studied electronics level 1 on 2009 let me read to refresh my memory and come back to you.
@@abdulkreemalsultan134 Yes agreed. I had this conversation before with someone; I’m sure there was a reason it didn’t work. Also I think I checked it with my multimeter 😁
@@abdulkreemalsultan134 Draw it down on paper and consider all paths when the injector is on and off. When the injector is off, that lead will be 12V, and the activated injector 0V, it can’t measure both simultaneously; the resistor is the answer. I needs current to flow both ways to make this type of measurement and circuit work. What do you think? The circuit will work but the oscilloscope wouldn’t measure what we want
@@MechanicMindset I have draw it with 2 idea I don't know how to send it to you so I just uploaded it as a video on TH-cam.
Either we use diodes or we can use multi relays driver L9026 I included the link for the data sheet for the L9026
th-cam.com/video/vkvLDBmArdM/w-d-xo.html
Looks like the secondary waveform is inverted
See what you mean, the spike seems to go in the right direction. May be down to the probe or could be that it’s wasted spark
Would love to see some more tests specifically on diesel and if possible wankel powered vehicles
Will try and get some diesel in soon. You know what, I’ve never worked on a Wankel engine ever!! 😳
@@MechanicMindset Good job, the 'SPELLING' of that engine design has been curated carefully , Lol 🙂, i'm an older Dinosaur, and have worked on a NSU Prinz, and a RO 80 ( Wankel rotary designs) from the 70's, but haven't seen hide nor Hair of anything that has survived from these older car's, but not any newer types,,,Yet.
@@sollykhan2385 Awesome! Were they good to work on?
@@MechanicMindset yes, they were in a strange way, futuristic tech back in 70's, the only problem was oil and water mixing and rotor tip's wearing away, i thought the tiny NSU Prinz was a cool car to bolt about in, till it broke down!! 🙂
The early Wankel engines were a pain in the butt to diagnose rotor tip seal wear and now with these modern products and oscilliscopes it should be much easier. We put a Wankel engine into a Lotus Elan and it was a flier leaving blue smoke everywhere !! 😞
Refrigeration pressure sensor for ac how look signal
Depends, some are varying voltage, some are PWM, some are LIN bus!!
