4. Press the button long time, insert the USB interface to enter voltage calibration:
For example:
(1) If display (5.526V Right indicator arrow) and then double-click the button quickly.
(2) If display (5.528V Up indicator arrow), can click the button to increase the display voltage.
(3) Double-click the button quickly, if display (5.528V Down iindicator arrow), can click the button to lower the display voltage.
(4) Then quickly double-click the button again, if display (5.526VRight indicator arrow), and then click the button once again, the screen will display the current calibration!
The system automatically performs the current calibration and automatically returns to the function home page after the calibration is complete.

A very useful review showing the hidden world of how many amps/milliamps different pieces of kit uses. Interesting! For me, I think the way the USB volt checker exposes different cables is very important. Basically, the el cheapo ones probably don't carry a good current - the more expensive (on Amazon, etc) are well constructed - and even have pictures of their cross section to show the quality of build. Yeah!

The view at 1:10 was interesting to me, as mine starts the timer the moment you plug it into a USB socket even if there's nothing plugged into the unit and starts seemingly recording it's own current use, about 11mA. This makes it impossible to know the real current use of small items as I don't know if when I plug something in and it says 25mA, is that the thing I've plugged in using 25mA or is only using 14mA.

Please help, how do I reset this thing back to normal, I got it this morning, I heard people talking about calibration, I went ahead and did it and I've since ruined it, because it's now giving wrong readings. Do you know how I can get it back to normal by reseting it back to factory default and secondly, what the heck is that calibration thing and what's the purpose? why do we do it? the first question is more important to me though.

How does that calibration work? Up down left right. Oh-so confusing, especially the Chinglish on sellers' listings! Horrid!

With respect to the usb heater, power is the product of voltage and current. The display showed about 2 watts. What were you expecting? The vest showed 9 watts.

I have the same voltage meter and I think is junk I drained my Tab s 7900mAh battery and after charging to 100% this voltage meter shows ~9000mAh capacity 🤣🤦‍♂️ I think you you want something good you need to pay more to get one that they use at repair centre
@marvincullianan6740
@marvincullianan6740 3 года назад
nope that 9000 mah is not its capacity. its the current that has been charge on it. so its basically has been charge means, it plus the system usage on the phone while its in charging. its the total mah

but you didnt unplugged it at exactly 100% charged. so current still flowing on the usb meter.
