- Hey guys, at the time of this video (March-2023) I didn't see any review in English (Only one in Japanese), probably because this T model is still new. This is a quick review - without getting into any PC connectivity.
In this review I am using a DJI Mavic Air defective battery pack as the load, by charging the 3-S cells directly - bypassing the BMS.
This is not a BK Precision, Sigilent Technolgies, HP, or other big-brand names. But, definitely meets the needs of a home workshop bench, and a nice value for money tool for the HAM / Amateur Radio shack / workshop.
Thanks for putting this video out. I bought my unit at a flea market, and of course it did not work even though the seller said it did. Every time I pressed "output" the settings reverted to zero. When I took the cover off I found a large copper coil was not inserted into the circuit board at one end of the coil (coil was leaning over like it had received a jolt in transit). I popped the coil leg back into the CB slot, and hey presto, a working unit, at a cheap price! The leg looks like it had not been soldered, so maybe unlucky for this unit, or maybe poor QC at the factory
Thanks for checking it out. Lucky you! Got it at a bargain. I bought a second one. Got it a bit cheaper as it was an Amazon return. Took a risk, and it's working well. The price will definitely go up as it becomes popular.

Thank you
Does anyone know how to save settings to Memory buttons (M1 to M6)
Mine forgets everything when I power off. Thanks!🙏
Yes. Double click the M button, quickly set the Voltage, and double click again. Be quick in setting the Voltage as it times out quickly. Same thing with current too. If the above procedure doesn't work for you then talk to the supplier for a return/refund.
Is it possible set current constant instead of potential?? I am doing experiments and I would like to keep the current constant and the potential can be changing. How I do that?
@@Dessa280810 Yes, it's possible - and easy. Use the I-cc button for that, and use the rotary knob to set the current. Save it in any memory for recall. Procedure is also in the manual. Good luck!
Mine WILL NOT SAVE any of the MEMORY locations M1 to M6
Hi just purchased this looks great but been trying to inject 1v 3amps to a motherboard but cant get it to constant amps anyway ideas thanks
Procedure to set 1V at 3A (in M1 memory):
1) Short press M1 once
2) Immediately use the rotary knob to set the Voltage to 1V
3) Immediately short press "Next"
4) Immediately use the rotary knob to set the current to 3A
5) Immediately press "Esc" (to save).
Hope this helps. I just now tried, and it works.
Thanks for checking out my video.
Hi, did the above work for you? I'm looking to buy one of these but that's the only thing putting me off. Thanks
@@Ben-rb9jj hi yes it did but very frustrating to set up,and in two minds to send back,as linier power supply are a lot easier to set up,just my experience
@@Ben-rb9jj yes, it works for me. I use it regularly. Purchased one more just before the prices went up. Now have 2.
They have some nice features not found in many at this price point.
The color LED displays are nice. I didn't want LCD.
how easy is it to remove the handle... I want to stack a multimeter on top but the handle means I can't...
I have not removed them so I don't know if there are nuts inside (must be). Otherwise, just 2 screws holding the handle. If there are nuts on the other side, you'll have to open the case so the nuts don't fall inside. Not difficult.
@@PremMenon thankyou.... one more question... is the metal body (not the feet) 150cm tall?
@@graxxor 147mm tall
@@PremMenonthank you.
Hi thanks for the video , I've just bought one of these for electroforming I need to set it to 0.2V 0.05amp in Constant Current when i do this it will only go to CV mode and the Amps disappears from the display , do you know how to get this to work please?
Thanks for checking out the video. Yes, you are doing it correctly. The set current shows 0 when you enable output, and will show the actual current drawn by the load - if/when you connect the load. Try to save your settings in one of the memories.
7 months late but if your plating cell resistance is too high, then you may need a higher voltage than 0.2V to achieve 0.05A of current. If you set your current limit to 0.05A and the voltage up excessively high like 5+V, then it will automatically drop the voltage down to whatever is needed to push 0.05A.

А у моего HANMATEK HM310T таймер работает в 1,25 раза быстрее. В 10 его секундах 8 настоящих.
Kostya, thank you for that information about the inaccurate timer. No, I haven't verified mine (I have two units). Never had the need for a timer so far, but I'll verify the timer in my units. Thanks again!
Для справки: в моём кварц на 25МГц.
Если ваш таймер работает правильно, то
можете ли вы по возможности посмотреть какой кварц на вашем блоке? Для этого достаточно снять кожух. Спасибо!@@PremMenon
@Koctya_Koctun Okay Kostya, I'll check the marked frequency on the XTAL used in my unit, and will report back. If not today, probably by your morning tomorrow. Hopefully that's also 25MHz.
@@Koctya_Koctun Hello Kostya, Y1 (XTAL) on my 2 units are marked 24MHz.
I just checked both against a stopwatch, and both seem to run about 10-11 seconds faster for every minute (on my stopwatch)! So, there's definitely a problem there.
If it's a different reference designator you are referring to, then please tell me the ref-designator (Y2?, Y3?). However, it's unlikely this will have more than one XTAL.
Сейчас открыл кожух и да, там кварц Y1 на 24МГц. Спутал, уже два года прошло. Уточняю, таймер ошибается в 1,2 а не в 1,25 раза. Версия платы: P_Show_V3.11 20210520
Огромное спасибо за информацию! Уже нашёл пользователя у которого та же что и у меня проблема. Если ещё не одели кожух, пожалуйста сообщите версию платы управления. Возможно разные прошивки. Ещё раз спасибо!@@PremMenon
How to set it in constant voltage mode?
Whatever Voltage you set is in fact constant. It'll reduce only when you exceed the set current - as in a short-circuit.
@@PremMenon I have a halogen lamp rated at 12V 60W if i set 12V 5A on the PSU voltage drops to like 11V and CC light is showing.
@@Dragunov1111 Set the current limit to 8A. It should work. Then find out the actual current drawn by your bulb. Keep in mind that such bulbs may draw higher initial current....and may draw more than the 5A "calculated" current.
@@PremMenon Ok now i get it so if i dial in 10V 5A it will go in CV mode as the voltage isnt dropping... Will try it later when i finish my coffie.
