Huanyang VFD current draw measurements.

Hi guys,
Then I used my ammeter on the mains power cable and it actually measured 0.8A. I trust this reading to be more accurate than the VFD panel reading.

You mentioned later that you're using a clamp meter. Quick question - did you position this around a single core of the supply. or the 3-core mains cable? If the latter, is your clamp meter designed for 2/3 core cables?, or a basic clamp meter? If the latter, then your reading is inaccurate.

It's a clamp meter designed to be placed around a single core, for example either the live or the neutral, and used as such. I have various dial ammeters that I could also have used, but for a quick cursory look, the clamp meter was more convenient.
