I have a Fluke 8060A multimeter that needs some help. Hopefully Dr. Taylor can shed some light. It's a recent eBay purchase described as "won't power up." Cosmetically, it was very clean and inside I easily found several old electrolytics that had "given up the ghost." At this point, the meter powers up fine, passes the power-on self test and appears to be working. Yea!
Not so fast. I've found that the range push-buttons are not being recognized correctly. Specifically, on performing the "switch decoding self-test" described on p. 5-22 of the manual, the 200 uA range switch and the 2000 mA range switch are both recognized as the 200 mA range setting. The 2 mA and 20 mA ranges decode correctly. I've tried cleaning the switches with De-Oxit without luck. I've also removed and re-seated the main measurement acquisition chip. I'd be grateful for any ideas.
