Insulation Resistance Testers | Major MJ159

Two models are available for general purpose testing which include a low-voltage model. Both are portable, self-contained instruments designed to give rapid and accurate measurements.

The instruments feature an analog display having four selectable test voltages of 100, 250, 500 and 1000 Vdc, measuring insulation resistance up to 2000 MO, and an ohm range to 5000 O.

The only other difference among the two models is the type of power source. Power for model MJ159 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. Power for model MJ359 is provided by 120 V ac 50/60 Hz or low-voltage generator.

Key Features:

• No scale multipliers
• Multiple test voltages for spot and step voltage testing
• Guard terminal to eliminate surface leakage current
