When measuring in-circuit, the 300mV test voltage may be very useful, as it in general does not activate most transistors, diodes, etc. If the reading was flashing (moving around, changing frequently) at 600mV, you may find that the reading settles down to just one reading that hopefully is accurate. Would like a short video update for in-circuit testing at 300mV, as you unfortunately did not cover that. Thanks for your work in testing this product. I appreciate it very much.
When the box is on display vertically, 1 year warranty is "UP" and both the other text is equally sideways. The voltage 0.3 is there for in-circuit testing where diodes might be present and you don't want to forward bias diode junctions, which reveals passive component performance more clearly. Usage rule of thumb to put yourself in the the most accurate range, use 10kHz for pF, 1kHz for nF, 100Hz for uF. Similarly, 10kHz for uH, 1kHz for mH, 100 Hz for H. Not only is the diode voltage low, the current is to. So the voltage drop across Schottky and silicon diodes are not accurate, because the current is close to the knee of the diode response curve. I agree - could be much better. Some other tweezers I have will do the job and also Zener diodes, but they are not LCR meters. Version 1.7 firmware has been released, includes the ability to log readings to a text file each time hold is pressed.
@@TheGrantourismo No. There's some info on the zotektools website: "1. Added the functionality to save and export measurement data. 2. Improved the accuracy of low resistance measurements. 3. Corrected spelling errors in English words."
Amazing! I have been offered one too and it looks like a decent LCR meter for a change :) it would be nice if it had 100hz as frequency measurement as well but I guess 1KHz and 10KHz would do. Thank you for doing the comparison, if I ended up making a video about it I'll point my viewers to this video for a reference with a proper LCR meter. (Edit - no, it can do 100Hz. I misread the feature list)
@@TheDefpom Yes, I'd agree. 10K or 100K won't probably matter for me. Thanks for showing that the tool is ACTUALLY using those frequencies when testing with the scope. I'm kind of reluctant in accepting those tools as most of the time they turn out being a waste of time but this seems decent - particularly for someone who doesn't have a proper LCR meter :)
@@tony359 These frequencies are only necessary for very low inductance or capacitance accuracy. Someone in the RF field might be more interested in 100KHz. It would be a real bonus, but requires higher slew rate components inside the meter. Davy Jones has a good review of how a LCR meter works.
@@pault6533 Thanks, I'll take a look. Indeed, the lower frequencies are plenty for my use - which is still to distinguish between "good" and "bad" caps :)
To me tweezer lcr meters are for checking surface mount component values during assembly. I would like to see how good they are for picking up and sorting components.
pretty much every device that has an LED, the manufacturer drives it as hard as possible to burn it out so you have to buy a new one! LED lamps for example specially do this
The bending of the tip, and the sharpening was the first thing I did to mine. They are suprisingly good for the money. Only thing to determine now is the battery life, but it does appear to charge quite quickly
What most people call 'OCD' isn't actually 'OCD'. OCD is not an adjective, it's a serious disorder 'hence the 'D' in it'. You are 'fussy', or something else when you dislike the fact that the image is upside down compared to the words, but you aren't "OCD", if you were, you would have been diagnosed with it.

Zoyi released two firmware updates recently. 1.6 improves the speed when measuring. 1.7 adds data logging by pressing Hold
does it add any new languEges?

Nice unit. Glad to see it can be configured for use by us lefties too.

@@tony359 Hi Tony, it does 100Hz, just not 100KHz, which is fine.

You sold me. Just bought 2x. Thanks....
It would be great if the measuring voltage and frequency were 0.1v/100khz
LED testing would be awesome.

Strange thing with the printing on the box is that the text is in the correct orientation on the side of the box.
In comparing with my old Mastech MS8910 these tweezers are in completely new level for less price. If you are on tight budget, no doubt the best.

Первый вменяемый обзор на этот девайс.
Nice review! Thank you very much!😀
I've just got a TechRed TR1061 LCZ meter, but can't find a manual for it anywhere.
Thanks mate nice one, what does the display item bottom right on the Capacitance display mean that starts with D:

Depends from LED position. You will not want status LEDs burning out, especially when status change is dangerous.
The bending of the tip, and the sharpening was the first thing I did to mine. They are suprisingly good for the money. Only thing to determine now is the battery life, but it does appear to charge quite quickly
Exactly! A little Dremel grinding & bending off the tips is all that's needed. 👍
if you don't want them I buy them off you give me 25. I can't get them from the net do parts suppliers sell them like farnell?
@@hoobsgroove purchase link is in the video description.
@TheDefpom I can't buy off the internet you near the southeast, trying to find a local supplier repair shop I can buy components my guy retired.
Miiiiau, the japanese yellow one is good (DE5000)
Thanks for the review. Will you review Fnirsi LCR-ST1 too?

Too funny, almost ironic. Only a person with OCD would take the time to post an explanation. 🤣
@@pault6533 Except that I don't have OCD. You don't have to have OCD to know it's overused.
Yes it is commonly used incorrectly. By the way, I'm a perfectionist but not very good at it yet. 🕊
I have C D O it is like O C D but in alphabetical order.
