The answer to your query is right. However, if you don't want to get that
brave, email me. I know of a shop that specializes in meter repair. I'll
get his name and address to you. I've known him for 45 years or so, and he
is very good. He did the meter repair and calibration for the QPL testing
that I did many years ago. Larry W9HTK

>If all that is wrong with you meter is that it binds, or will not zero, it

>You can remove them by first cutting narrow slits of cellophane tape. Using

>the meter. The metal fragments will stick to the tape. Change the tape
