Product Details:
Two-pole voltage testers generally have a self-testing function to check the unit is working and does not have exhausted batteries. This test does not necessarily indicate the instrument will safely show a voltage measurement, particularly voltages more than 50 volts. Two-pole voltage testers are recommended to be tested with a known live voltage source prior to making a voltage measurement on a circuit.
The Megger MPU690 proving unit provides an alternative portable battery-operated voltage source that can verify the correct functioning of a voltage tester. The device safely generates a range of voltages from 50 to 690 volts in five steps.
A switch on, the unit initially generates 690 volts then after a short period, slowly ramps down through each voltage step until the device switches off. The individual voltage steps are indicated by an LED with a power indicator LED that also indicates an exhausted battery. The MPU690 features automatic power when voltage tester probes are inserted into the output terminals, generating a 50 Hz output voltage that simulates the AC mains supply.
