I just replaced the lithium battery in my 54512b and am now trying to recal. The scope passes all the self tests and seems to work fine, but when I run the vertical self cal, I get the error messages:
FAILED A/D CAL
FAILED GAIN CAL
I get the same errors for each input channel. The scope is in the unprotected mode for this procedure.
Thanks for any help ar advice.
