Thank you for update. Would be great to see firmware change notes as well though.

Hello friends from ZOTEK! You must fix one significant drawback, I'm sure that all owners of this model ZT-702S will agree with me. The problems is that: 1). The device does not remember the last operating mode after turning off. It would be perfect if the device began to work with the last mode used. Correct the firmware, please! Because now, if i need to use the measuring mode of the capacitors, I need to press the buttons 6 times (!) each time after turning on the device. This is the main problem of this device, and you simply must fix it as soon as it posible. 2). And the second problem, this is in the oscilograph mode: the yellow line is lower than the center of the yellow triangle. The yellow line is not displayed correctly, it should be slightly higher.

Hello Zotek, I have just purchased this oscilloscope and really i love it. But i would suggest two improvements for future firmware updates to make it even better: 1. Can we have a duty cycle measurement in oscilloscope mode? 2. Could the display of the multimeter have two modes. One with the bar graph and other view without bar graph and bigger numbers?

@hhKJgf1M8a0rzt8hP

It seems the duty cycle measurement was added to the oscilloscope mode with firmware 1.03.58. For the measurement to be displayed one needs to turn on the "MoreMeas" option in the settings menu.

Please tell me How to get that firmware?

Changelog??? I think there is a massive waste of screen space also, I think everyone would be happy with just a small bar graph at the very top edge of the screen, perfectly horizontal, next to the battery level indicator, at the same height as the battery icon. That would be plenty. Even if you made the bar graph as high as the battery icon and then had an indicator needle for the bar graph that was the same amount of pixels underneath (so the bar graph and the indicator needle was twice the height of the battery icon), that would leave such a super massive area to enlarge the digits. I'd maybe save space and choose to run the needle through the bar graph though, rather than underneath it. Obviously its a great product if the main thing people complain about is just the digit size and the power-on setting memory. It seems easy and a no brainer to fix these little things. Personally, I wish it was a device tester too, but how much would that raise the price? I have to settle for the DSO-TC3

Thanks! I like this device and ones like this. What is very important to me is a fast update rate. When I use the oscilloscope, I want the screen to update like 10 times per second. It is very important when I use it to analyse audio for example, or even voltage drop etc. I know it can be harder on the battery, but if it has a rechargable battery then I don't think it's an issue. Or maybe fast refresh could be an option you could turn on or off. I hope you continue to innovate!

As of today, I don't see any significant difference. The device's algorithms may have been changed/improved. The only difference I noticed is that when you turn on the scope, the multimeter displays the bar graph first and after a second the digital indicator. In the previous version, the entire multimeter screen was displayed immediately. I wrote to the manufacturer about the changes compared to version v31.03.51 - I did not receive a reply. Regards.

I received it recently and I have been quite happy with it (almost). I am more interested in the multimeter mode, the oscilloscope is what it is. It came with 10.3.55 and I did not upgrade yet. Is it worth upgrading? One user noted that autorange did not work for capacitance. It seems to work on mine but you cannot switch it to manual for capacitance. The "analog" meter is useless for me as the refresh rate is to slow, the scale is always 0-100 and it has this ugly red tint below the meter. The space could be put to a better use. One thing I don't like very much in multimeter mode is the function keys: First mA should not be F4 but F3 to be close to V and A. For consistancy it should also have just AC / DC like V and A. Doing so would make F4 the key for all the other functions which is not very pratical but there is a simple solution which should not be very difficult to implement: In multimeter mode the arrow keys are not in use. Put them to good use by having 2 sets of function keys which can be switched by using the right and left arrows. First set of function keys: F1 V, toggle AC / DC F2 A, toggle AC / DC F3 mA, toggle AC / DC F4 Resistance, toggle Ohms / Continuity Press the > or Second set of function keys: F1 Diode F2 Capacitance F3 Temperature F4 Could be used to display the battery voltage Any function can be accessed with a maximum of 3 key press. 3 are needed when the 2nd set of function keys is active and you want to access the 2nd function on one of the 1st set of function keys: 1 key press on , and 2 key press on the function key. This would make the multimeter use way better than it is now.

FYI, I updated my Xeast branded 702S with the Zotek firmware without any issues.

Здравствуйте, есть баг в осциллографе, в режиме DC не всегда коректно измеряет Vpp (Vmin) , очень часто Vpp 2 раза больше чем на самом деле, потому что Vmin вместо 0,0 имент примерно такое же значение как Vmax . Это происходит тогда когда Vpp около 4-5V а 1 деление равно 1V. Hello, there is a bug in the oscilloscope: in DC mode it does not always measure Vpp (Vmin) correctly, very often Vpp is 2 times larger than it actually is, because Vmin instead of 0.0 is approximately the same value as Vmax. This happens when Vpp is about 4-5V and 1 division is equal to 1V

@andreyn1719

Прибор в режиме калибровки от встроенного генератора, при включении автонастройки растягивает сигнал на весь экран. При этом среднеквадратичное значение показывает правильно, а Vpp действительно показывает ошибочное и неустойчивое значение. Но если сигнал уменьшить до 4-х клеточек экранной сетки, то снова все работает нормально в плане измерений. Таким образом сигнал должен быть 4 клетки от нуля в верх и вниз, тогда Vpp показывается верно. Если же от нуля вверх идет более 4-х клеток, то Vpp уже прыгает и неустойчиво отображается.

Please correct a bug in VPP and DUTY measurements in DC mode in FW v1.03.58.

Hi. When will the software version for this device 1.03.55 become available on the website? She's already out. I saw it in the ZT 702S review.

I used mine once and now it refuses to form a trace. The multimeter works and when it is in scope mode it shows voltage at the bottom of the screen. I know it was only $70 but dang, that was pretty crappy. I'll try this software update and see what happens.

Como atualizar o firmware? Onde posso baixar um novo firmware? Este equipamento é igual ao Zoyi, mas o Zoyi tem atualização de firmware e este não encontro.

Witam, gdzie na nowej stronie znajdę linka do pobrania firmware do ZT703S?? P. S. Bardzo fajny oscyloskop!

Does the 702s allow oscilloscope voltage readings up to 220/240v to observe the sine wave of the AC power signal. If it doesn't can this be made available later through a software update. The multimeter mode has no restrictions on this voltage level. The documentation isn't very clear whether the 10x probe allows this.

This manifests itself in the form of a small periodic flickering of the upper part of these elements on the screen.
