The insulation meter measures with a test voltage of up to 15 kV. The measurement range of 0 ... 30 T? and other measurement functions make this insulation meter extremely versatile. It has 4 quick selection keys of the test voltage and the option to adjust the voltage in steps of 500 V. The insulation meter integrates preconfigured diagnostic tests, a polarization index (PI), a dielectric absorption ratio (DAR) and a memory capable of storing 200 values.
