Description
This insulation tester is capable of measuring 250V, 500V or 1,000V test voltages and insulation resistance up to 2000MΩ.
When undertaking power installations, the 420001-insulation tester can provide special help to test wiring. This unit can provide 125V,250V, 500V and 1000V source for the test, and under each range it can supply 1mA current to feed the capacitance load. With the auto-range function, it can measure up to 4,000 Mega ohm with the resolution of 1Kohm.
The unit features a large, easy to read dual display with analog bar graph and backlight, and min/max recording & data hold functions. Auto-discharge of capacitive voltage for added user protection, live circuit detection prevents insulation test if voltage >30V for added safety.
This is a complete kit which includes 6 AA batteries, users manual, test leads, "crocodile clips", strap and a hard plastic carrying case.
