Safety Voltage Indicator Tester

• Essential equipment for safety compliance
• Long-life battery operation
• Belt-clip mountable

The P240 is a hand-held battery powered proving unit that provides a nominal 240V dc, 2mA source intended for proving the integrity of neon type test voltage indicators.

For safety compliance, voltage indicators should be checked for correct operation from this known voltage source before and after every use.

Testing is performed by inserting the test probes of the neon tester into two recessed "touch proof" terminals on the proving unit. Insertion of the probes automatically turns the proving unit on thus eliminating the need for an on-off switch.
