Panasonic Microwave using 70W all the time

It is the Maplin meter which I have got on loan at the moment from a mate of mine. I just wanted to be nosy6 to see how much power things take. since my mate had a meter, I borrowed it.

I have spent a few hours yesterday attempting to confirm the 78 Watts drawn in standby as indicated by my portable meter:
I first turned off all electrical appliances and confirmed that no current was drawn on the main power meter of my house.
Then I plugged in the microwave (standby) and worked out the consumption: If was definetly less than 5 Watt!!!
So the Microwave is fine after all and my portable meter can somehow not cope with this device. It was indicating a power factor of 100%, perhaps it can not work out the power factor of the microwave?

I would get that checked 70w,s cant be right

I'm sure you don't actually mean 13W when it's cooking food! If your meter actually says 13W - it's broken! It should be more like 500 - 800W - check the label on the back.

Does it cook the food just using the light bulb inside it?

Surely the drive mechanism that spins the turntable inside it should use at least that, and the bulb at least that again before the microwaves are even generated.

I tested my Panasonic microwave (Clock only) at the weekend using a calibrated meter. Came out at 81.6 watts.
It is now turned off until I need it!

That was 81.6 VA not watts. They are normally the same but not with same devices with high inductor circuits.

Turns out its only 3 watts !!!!!

Panic over!
