I am in the UK. A home power meter I bought says this in its
Chinese-English instructions. Can anyone make sense of it?
Press 'WATT' display Watt meter, then press
key to display VA meter, and active power
for 1 second each automatically.
'WATT/VA' Key is a toggle function Key, the
LCD will show Watt is the active power,
and VA is the apparent Power. (VA = Vrms Arms)
There seems to be some difference between V multiplied by A and
It mentions "apparent power" but what is it?
This is the meter:
These are the instructions (see #5):
It looks quite like the US's "Kill-A-Watt" Electric Usage Monitor
