Multimeter Calibration?
What is the best way to check your voltmeter? Some years ago I ran into the problem where the meter read voltages too high when its battery was low. That took a while to discover since it happened...

If you have a HF mulimeter there is a pot inside that will adjust the voltage readings. I use my B&D charger and adjust the voltage reading on my HF meter to match it. I have about 4 meters that I use in the RV,house and car now that all read the same now. I used to use my friends Fluke meter to adjust my HF meter but he moved away.
Never thought of that! VEC1093DBD on a battery the meter said is 13.14, the VEC said 13.2v. That was with it clamped to that battery and plugged in saying 000 but not set to charging.
This was in the unheated garage. The VEC has temp comp voltage.
