UPDATE. Oct 2024. With the new 1.4.2. firmware update we now have a third trace available in the form of "FFT" (FAST FOURIER TRANSFORM) availability in glorious RED colour. It replaces the FORMAT position in the fourth menu which was used to delete the stored screen shots. It changes the "X" axis from time to frequency and as such changes the display to that of a a spectrum analyser. Frequency is plotted along the x-axis and amplitude is plotted along the y-axis. FFTs often look like a series of mountain peaks. The horizontal location of peaks indicates which frequencies are strongly present in the W/F. The valleys show which frequencies are absent. I tried this with the built in calibration sig gen on all the available W/Fs and it shows the strongest frequency is the prime 1 KHz followed in the case of square waves by diminishing amplitude peaks at each successive square wave. Quite useful when checking audio problems etc. The second change in the menu is in the 2nd row, what used to be the trigger position, is now "SAMPLE" with two choices, HD & PEAK.
Would it be possible for the company to provide revision history for the firmware which includes what features were fixed? It would be well received by purchasers / users of this great product@@zotekmultimeters4774
To add a bit more , I had good intentions to buy it for a thorough and quality testing of the device, which I would make a video about on my channel. However, after reading some feedback from those who have already purchased the device, I noticed that many complain about the build quality and performance, so I decided not to go through with the purchase. I think you should send this device for review to some independent TH-camrs who will provide a genuine and unbiased review. Personally, when I make such content on my channel, it is impartial and truthful, regardless of whether it is good or bad.
I think (just because it's NOT build in the USA) , you wanna get any ?independent? testers. Just watch and listen to the videos. Do you give your Hi-Tech Homestudio in theire hands ? :D
frmware version 1.42 still has a lot of bugs related to auto range. The function still often sets the wrong waveforms and after pressing the auto range key, the sample HD function turns off by itself. when are you working on releasing the next version of the firmware?
Hello, Can you add a automatic data hold function to the multimeter, in the future updates? So that, when i probe someting, i dont have to look the screen and it would hold the highest value until reset. There is already the hold button. Thanks
Is this the real ZOYI ZOTEK Channel ? I have 2x 702S and a new 703S. Why have those some 'rare' jumps in the Timebase? Normaly it's 1-2-5 , yours have some 1.25 , 2.5 ... ..and: what is the meaning for the red marker 703S (on top /middle screen)

I would have bought one already, if not for the quirks/bugs found by comprehensive testers on YT. Hope that Zoyi would fix these quickly.
We have fixed the bugs via updating the firmware. Thank you very much!

Thank you for your suggestion.
Firmware v139 is out - Why not standard 1-2-5 for Volt & Time Scales ?
Looks nice, maybe it is better then similar from other manufacturer's but that is left to be tested.. Thank you for this video
Thank you!

I'd like to ask
Can the oscilloscope measure voltages up to 400v?
Seems like the DMM can read up to 1000VDC, and 750VAC according to the specs. I don't know when the OScope mode is active.
Set your probe and the scoop in x10 - if you have FW v138 or v139 you also can use a x100 probe.

(on top /middle screen)
Yes, this is Jully from ZOYI. The red mark indicates the middle of the screen. Thank you!
экран очень хороший.
Thank you!
It's very annoying that the screen turns off every two minutes.
I’m guessing that’s the default value for battery savings. Should be adjustable in the settings
@@TheConner322 Ok I found it, set BL time to off. Thanks.
