Review on DROK 090554 Ultra Small 0 100V Motorcycle by Fredo Zhan

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 sometimes and others like now I just got a 5.0 reading when my DMM was 4 .74 indicated. For my purposes. 25 volts is a big discrepancy and renders the display useless to me. It is very important for the electronics whether it is supplied with 4.74 V or 5.0 V, I ordered another 3-wire block that shows two decimal places and hopefully everything is more accurate there. PS Gorse - I would have paid a few bucks more to get a more accurate device. PPS DROK - why are 3 wire devices with 2 decimals and enough precision to make the last digit make sense so hard to find?
