Is the 15V battery good?

AC ranges could be the rectifier or current transformer perhaps. Have you got the circuit diagram?

Hi Eric,

Herald1360 has pretty much summed up the most likely culprits.

Check out this similar thread which deals with a similar problem

Regarding the Zeroing of the x100, definitely check the 15V Battery,
but don't forget to check for any corrosion on the Contacts and make
sure their clean.
This can catch people out.
