5kV insulation tester, battery-powered, analogue/ digital LCD. A built-in timer makes both spot tests and Polarisation Index (PI) testing easier to carry out.
Pre-set standard test voltages at 500V, 1, 2.5 & 5kV with variable test voltage in 25V steps. Displays capacitance at the end of a test to 10µF. Performs automatic PI, Step Voltage and Dielectric Discharge tests with an optically isolated RS232 port for downloading results during a test. Short circuit current: nominal 1.8mA, max 2mA. Battery life: typically 8h.
