HP Agilent 3478A 5.5 digit LCD Digital DMM Multimeter GPIB -Uncalibrated
The old battery was disconnected when I opened the top cover (3rd picture). I have removed the old battery and have not installed a new one (4th picture). You will need to install a new battery and re-calibrate.
Inputs tested were:
5VDC -> ok
5 VAC -> ok
100K Ohm (2W & 4W) -> ok
1mA DC -> ok
1mA AC -> ok
Power cord and leads not included.
GPIB is working ok.
