DROK Meter showing incorrect Voltage (Problem Solved) Battery Capacity Amp Watt Tester Hall Sensor

[@shawnl4073]

Thanks for posting! I recalibrated my meter which was off by a good 0.2 volts. Also, I believe the 10V and 40V settings are calibration points at 10 volts and 40 volts. You produce each of those voltages (or something close to them) to do a proper calibration at the low and high end of the sensor’s range. I assume there is variability since the meter and its screen pull nontrivial current which would cause voltage sag on the thin gauge battery sensing wires.

You're welcome, glad to help! You're right, I did a little reading since the post and that was what others have mentioned.
