DER EE – Analog Insulation Resistance Tester DE-5010


Analog insulation resistance tester is a portable, self-contained instrument designed to give rapid and accurate measurements. It has four selectable test voltages of 100, 250, 500 and 1000 V dc, measuring insulation resistance up to 2000 M-Ohms, and an ohm range to 5000 ohms. Power is derived from a low-voltage, hand cranked generator which has been designed to be easy to turn even under full load conditions. The low-voltage generator is connected to an electronic inverter to provide a very stable test voltage. Accuracy of measurement is unaffected by variations in the generator cranking speed and the test voltage is maintained at its rated value.
