Hey all – has anyone else notices that the Real Power measurement, when on AC current (internal shunt) and AC voltage (such as measuring power to a AC appliance, where AC current is measured on the neutral wire, AC voltage measured to the Live wire) seems to have a rogue minus sign?
I double checked my connections, since AC current and voltage are RMS, they are always positive on the display. In graph/buffer mode, when the voltage and current are clearly 180 out of phase, the Real Power is positive; when V and I are in phase, it reads negative — opposite of what they should be.
