Fluke 845AB High Impedance Voltmeter / Null Detector
All I know is the battery was dead so I charged it over night and in the morning when I tested the meter went immediately to the Battery OK position. Also next to the zero knob what ever was there is sheared off to the face and needs to be replaced.
Even though I am familiar with most of the equipment I am not a technician and can not check this item out beyond a basic power up and/or self test if that function is available. I try to describe as accurately as possible and list as much as I know about the item. I also pop the covers when able and inspect for missing or burned components, water damage, obvious signs of attempt at repair, and anything else that is obvious to someone with a limited technical background
The Fluke 845AB Null Detector is an all solid-state null detector designed for extremely high input impedance, sensitivity, and isolation. Operates from either AC line or Battery.
Offers 19 ranges from 1 µV to 1000 VDC.
Input isolation is greater than 10E+12 ohms.
Input may be floated to 1100 V above ground and overload protected to 1100 V on all ranges.
Recorder output isolated from input
