Measures Insulation Resistances Up To 1 T Ohm
Simpson’s Model 505 High Voltage Insulation Tester is capable of measuring
insulation resistances from 10 kilohms to 1 teraohm with eight selectable test
voltages up to 5000 V. As a safety feature, the insulation tester acts as an
AC/DC voltmeter to measure the absence of voltage in networks up to 2000
V. For added safety, the cables are permanently attached, preventing possible
injury that could occur by the accidental removal of the cables. The Model
505 features automatic discharging capability of capacitive units under test
and a lock in test switch, for hands free operation. An optional guard terminal
is available to minimize surface leakage errors. There are two LEDs to
indicate the selected measuring range, and one LED signifying valid measurements
and battery charge status. Each tester comes in a padded carrying
case with permanently connected cables and test probes, 2 alligator clips
and a plug-in battery module with batteries.
Eight Test Voltages: 100, 250, 500, 1000, 1500, 2000, 2500, and 5000 VDC
