DROK 090554 Ultra Small 0 100V Motorcycle Review

smaller than I expected but no problem, works well, calibrated correctly and delivered surprisingly accurate. The only downside I found is the exposed circuitry on the back. Being clumsy, I accidentally flipped the display on its wires and the circuitry on the back touched the battery positive terminal. I tested it, it still works, but now the first digit segments are lit at about half brightness. I recommend putting a piece of tape or whatever on the back if there's any chance of it coming…

I like the fact that it supports 3-wire because the device I'm trying to measure can't support drawing this display. And of course if it could support the display I could connect it as 2 wires. Very flexible. I like the display itself and it took me a while to adjust the potentiometer to sync the voltage reading to my DMM. Unfortunately, I found that the last number is actually inaccurate. I'm trying to measure ranges between 4.7 and 5.4 volts and even after calibrating I can see it's dead…

It's small! I know the size is clearly marked, but I was still surprised. You can connect this meter in two ways: 1) 2-wire: black to ground, red and white to pos. energy source. The meter is powered by the same source that it is measuring. Pros: Easy setup, only 2 wires required. Good for placing cars. Disadvantages: limits the measuring range to approx. 3-30c. In a dark room I could see the display at around 2.4V, and at around 3V I could see it in a lighted room. It seemed to reach full…
