simpson 505 High Voltage Insulation Tester
simpson 505 High Voltage Insulation Tester
Measures Insulation Resistances up to 1 T Ohm

Simpson's Model 505 High Voltage InsulationTester is capable of measuring insulation resistances from 10kilohms to 1 teraohm with eight selectable test voltages up to 5000V. As a safety feature, the insulation tester acts as an AC/DCvoltmeter to measure the absence of voltage in networks up to 2000V.

For added safety, the cables are permanentlyattached, preventing possible injury that could occur by theaccidental removal of the cables. The Model 505 features automaticdischarging capability of capacitive units under test and a lock-intest switch, for hands free operation. An optional guard terminalis available to minimize surface leakage errors. There are two LEDsto indicate the selected measuring range, and one LED signifyingvalid measurements and battery charge status. Each tester comes ina padded carrying case with permanently connected cables and testprobes, 2 alligator clips and a plug-in battery module withbatteries.
