Measure insulation resistances up to a maximum of 4000 MΩ with test voltages of 125/250/500/1000 V. Additionally, the ET-100 offers measurement functions for DC and AC voltages up to a maximum of 1000 V/DC and 750 V/AC in CAT III, as well as for resistances up to 400 Ω. The included shoulder bag allows for comfortable operation of the device, as the ET-100 does not need to be held in hand during measurements. The molded soft rubber protection ensures that the device is ideally protected.
