Fluke #10 DMM Multimeter repair

Hi,

Purchased an NOS Fluke #10 DMM. It was apparently shipped with a factory defect, no doubt that it was never used. When you flip the switch to its first position (volts), the display either does nothing or throws up random garbage.

If you quickly slide the on-off switch all the way over to the right position, the ohms/diode section, the meter works fine in that mode. Sliding it back to Volts again causes some random garbade to display, then display quickly fades out.

Anyone have any idea what is causing this problem? I tried spraying the on-off switch to no avail, and a new battery was installed (although the original was still good). Meter looks like it may date from approx 1997.

If there is no warranty or possibility of returning the unit to the seller, then your best first step is to replace the electrolytic capacitors in the unit. I have the User's Manual and the Service Manual for the model 10 if you need it. The service manual contains schematic and parts list. I can email them to you. Both are PDF files, totaling about 9 Mb. There is no theory of operation or troubleshooting info in the manuals, so you're left to your own expertise. If the trouble points to the LSI chip, parts availability might be a problem.

I went to a bookstore and asked the saleswoman, "Where\'s the
self-help section?" She said if she told me, it would defeat the
purpose.

Hi Dave,

Thanks for replying. I sent you a quick email, if you could forward those PDF, that would be great. Please forward them 1-at-a-time, because my email has a 10mb limit, so both at once may cause it to bounce.

thanks again.
