I'm looking for help with my 8060a. I have 2 problems.

1. After power-on I get a "- OV". Normally an "OV" means that you are
out of range...I never see a "-" sign there. I cannot make any
measurements.

2. I performed the Switch Test and compared it with the values in the
manual. It looks like switch sw6 (200mA) and sw5 (20mA) are not working
correctly ... I get a zero value instead of the values in the manual.

Any ideas on issue 1?
Are the switches replaceable and would you recommend doing that or any
suggestions for repair. I cleaned all contacts with isopropyl alcohol.
And blew out dust with a can of air.

thanks,

On one of my 8060s, the MAC (measurement acquistion chip) had come
unseated from its socket. Unfortunately, the voltages on the pins still
connected zapped the chip. Last Dec 31 was the last order day for 8060
parts (I called on the 29th) but there were no more available. I bought
a partly trashed 8060 on ebay which had a good MAC. Only way now to fix
an 8060 is with a 'donor'. Sorry for the bad news.
