Check the listing for details. Hewlett-Packard Model 431B Radio-Frequency Power Meter. Condition: For parts or not working. Listed at 25.54 USD. When powered up (using clip leads) the pilot light comes on but the is no movement of the meter and it does not respond to the zero adjustment control.

These units are untested.
