@wntrhwk Yes. That’s probably what @ville is trying to say. Rotating “com to amp and amp to com” will take care of the negative values. “A” and “C” are connected in the Mooshimeter (that’s why you can measure amps) and switching the probes will alter the “direction of the current”.
the Mooshimeter will not take any damage anyway you connect A and C in this case. All (at least all i have tried) multimeters have the ability to measure with power in both directions. Adding a negative if needed. That’s the easiest way of seeing what direction the power are going. For example; it’s very useful to know the direction of the current when you are working with diodes (leds and so on).
