Test Voltage
The IRM-5000P can perform tests with preset voltages (500, 1000, 2500, 5000 Vdc), or with user-selectable voltages ranging from 50 Vdc to 5000 Vdc with a ±2 Vdc resolution.
Polarization Index (PI) Test
PI tests can be run at preset voltages (500, 1000, 2500, 5000 Vdc) or at a user-specified voltage from 50 Vdc to 5000 Vdc. Test results can be printed in both tabular and graphic formats.
Step Voltage (ST) Test
The ST test measures insulation resistances in five equal voltage steps up to a fi nal test voltage of 2500 Vdc or 5000 Vdc.
The voltage is stepped up in 1/5 increments of the fi nal test voltage every one minute, five inutes, or other user-defi ned time interval.
Dielectric Discharge (DDS) Test
The DDS test measures the dielectric absorption of an insulator. This test can be used to diagnose an insulation problem in cases where multilayered insulation is used.
