Power for the MJ10 instrument 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.
- Standard d.c. test voltages 100V, 250V, 500V and 1000V
- Guard terminal
- Continuity range with polarity reversal
- Automatic capacitive circuit discharge facility
- Voltage range for indicating an energized circuit and monitoring discharge
As a safety feature, the a.c. voltage range becomes effective as soon as the instrument is connected to the circuit under test. Thus, a warning is given that the circuit is not de-energized before the instrument is operated.
