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 Watts?
It mentions "apparent power" but what is it?
