Features
  • Broad Range of Testing Voltage:
    1. Testing voltages with broad range can be generated (from 250 V to 5 KV).
    2. Testing voltage can be preset as 250 V, 500 V, 1 KV, 2.5 KV, or 5 KV, or as a voltage increasing or decreasing in steps of 25 V or 100 V.
  • Insulation Diagnosis:
    1.PI and DAR can be automatically calculated and displayed;
    2.Step-voltage measurements and temperature compensation is carried out.
  • Large Storage Memory:
    1. Up to 100 manually tested data and 10 groups of log-test data can be saved.
    2. Test data can be read on LCD, or uploaded to PC
  • Clear Display:
    1. Large-screen display. Test result is displayed with indication through a graduation bar.
    2. LCD screen is backlit, which is suitable for viewing when it is dark.
  • PC Communication:
    1. The meter is equipped with a USB interface, through which the saved test data can be uploaded to a PC for further table/figure making and report generating with convenience.
  • Robust and Durable:
    1. With a compact structure, the tester is robust, durable and portable.
  • Powered by Batteries:
    1. With a selection switch, the tester can be powered by an alkaline battery.
    2. This tester can be continuously operated for a longer period of time than similar meters if a LR14 alkaline battery is used.
