Fluke 887AB Differential Voltmeter

Description

Fluke 887AB Differential Voltmeter
This is a nice clean unit.
Photos show measurement of a AA battery.
Photo 3 - shows a little over 1 V on the 10 V full scale. (TVM)
Photo 4 - shows the Fluke 887AB after I nulled the meter at maximum sensitivity. Voltage reads 1.35362 V
Photo 5 - shows the battery measures 1.353 on a DVM.
Photo 6 & 7 - I removed the top cover. Looks clean inside.
I haven't used this in years. I had to rotate the switches back and forth a few times to get it to read correctly. Some DeOxit on the
switch contacts should fix any dirty switches.
I'm an electrical engineer and getting ready to retire so I'm selling the electronic test equipment and standards I've acquired over
the years.
