Megger 212159; MJ159 (6410-863) Hand-Crank Analog Major Insulation Tester; 100 to 1000 V MJ159 (212159)

Megger 212159; mj159 (6410-863) hand-crank analog major megger insulation tester; 100 to 1000 v quality is crafted into megger 212159 mj159 major megger hand-cranked insulation resistance tester with excellent test voltage regulation direct measurement readout and an external guard terminal to eliminate surface leakage current from the measurement. It is portable self-contained instrument designed to give rapid and accurate measurements. Megger 212159 mj159 major megger hand-cranked insulation resistance tester features an analog display having four selectable test voltages of 100 250 500 and 1000 vdc measuring insulation resistance up to 2000 mand an ohm range to 5000'. Power for 212159 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.
