This thing has performed flawlessly for many years, but when I turned

it
on
today something was not right. The ohms range flickers random readings,
with
no probes plugged in I get around 230K on the display, or 2.22M,
depending
on the range, which would imply that the problem is ahead of the

scaling
circuit. When I switch to the low ohms range, the reading starts around
240
ohms and then drops to -0.00 over a period of 10 seconds or so,

frequency
reading works, but AC volts reads 70mV when plugged into a 120V outlet.
Something strange is going on! I realized that I don't currently have a
backup meter, I suppose I could use this as an excuse to buy a true RMS
Fluke, I don't think I can bring myself to buy a cheapie, except

perhaps
as
a backup. Anyone run into this?


Is the fuse intact?


I assume so, I didn't do anything that would blow it, but other times the
fuse has blown it has not exhibited any unusual behavior. I know what I'm
doing, I tried all the simple stuff, something has failed.




If the fuse is blown you get a consistent reading of about 1 per cent of the
true reading.
