Mistake busbars ?
#15
@wim: thanks for the correction on my correction that needed a little more correcting. Wink

Well, I wouldn't quite say deci/centi-volts aren't real. Most MM's are either xxxx, xx.xx, xxxx. Or, at least the few different ones I've used only show those 3. So we readily use, or have access at least, to all 3. On packs that are over 4 volts, I'm sure we all use the deci-volt mode as we only need to see the tenth of a volt. I'm not sure how far the MM will go in centi-volt mode. I know they have kick offs at certain voltages and I don't have a variable PS to test mine (yet).

Hrmm, actually, there are 5 settings. HV (High Voltage; not sure what it's range/max is), 200 (00.0), 20 (0.00), 2000m (000), and 200m (00.0 ?? I'm guessing this is fractional millivolts, or, pico-volts. it's sensitive enough that moving the wires slightly generates a voltage).

But we are really interested in the main 3. However, you could use the 2000m setting to detect voltage drift across the pack as it's that sensitive. I'm guessing you could use 200m as well, but you'd need to not move the wires afterwards to make sure you get an accurate reading.
