I just bought 2 of these LCD panel meters. CX101BG (For common ground). They're BOTH wildly inaccurate.
I have the inputs connected per this post. https://www.edaboard.com/threads/123247/ Post #4 (I've attached the schematic from that post)
I have mine configured using a divide by 10 divider (1M & 100K). 1.86Vin (before divider) = .171V (after)(tolerances, etc) at the CX101 inputs. Voltage measurements taken with a Fluke 189. I have the decimal point in the first position so the display should read 1.710V. But I can't get anywhere near that. It reads 1.008V. Even if I turn the trim pot on the back of the CX101, it doesn't even get close. Am I missing something?
