Benning Insulation Tester, 20GOhm,

Measurement of insulating resistance and calculation of the resulting leakage current. Selectable limiting values for ISO measurement, green LED for “PASS”, red LED for testing voltage/external voltage. Measurement of polarization index (PI) and dielectric absorption rate (DAR). Internal memory for 100 measuring values per measuring function. TRMS voltage measurement with low-pass filter.
