Testing a Multimeter

Guest
Hello all,

I am looking at buying a used Fluke multimeter (either an 8060A or a
77-III) from a local guy and I would like some simple tests I can do on
each meter. Neither meter has a current calibration so I certainly
don't expect the either to be perfect. I may send it off for a proper
calibration after buying it, but at this point I'd just like to test
that the meters are fully functional. I have a regulated dc supply, a
new carbon-zinc battery and some 0.02% resistors (1,100,10K) that I
could bring for basic circuit tests. Beyond the occasional
household/automotive troubleshooting, I don't do much with AC and the
meter will primarily be used for building some hobby circuit work and
testing DC circuits. If the dc voltage, dc current and resistance all
checkout ok, can I assume the AC functions are ok? Beyond obvious
signs of damage, Is there anything in particular I should look out for?

Thanks,
Jamie
 
If both meters are functional you can cross calibrate to see if one of
them is damaged. As long as the readings are withing the meter's
specification you should be o.k. You can use your power supply and
resistor assortment to check out the resistance, D.C. voltage and
current ranges.

You can do a crude check of the A.C. by checking the mains. If your
bold enough (balls enough) you can use your resistors to exercise the
A.C. ranges on the meter. CAUTION: IF YOU DON'T KNOW WHAT YOUR DOING,
I WOULD WARN AGAINST DOING THIS. IT COULD BE FATAL.
