The Martindale PD690 is a low weight portable proving unit for the testing of contact type voltage detectors up to 690V.
To operate the unit, place one probe of the unit under test into the left hand socket until it makes contact with the terminal. Place the other probe into the right hand terminal and press it down until the light on the PD690 high voltage indicator illuminates and the probe makes contact with the terminal.
Take the readings of the unit to be tested and then remove the probes starting with the right hand side one and then the left.
The unit is battery powered (6x LR6 1.5V alkaline batteries) to maximize portability and to help users access to hard of access areas.
