Ermenrich Ping ET50 is an insulation resistance meter, or megohmmeter, which is used to check the quality of cables. Damage or deterioration of the insulation on a live cable can lead to short circuits and fires. Regular megohmmeter inspection reduces the risk of such dangerous situations occurring. The device operates at 5 test voltages: 100, 250, 500, 1000, and 2500V. The total resistance measurement range is from 0 to 200GΩ.
The device also measures two additional parameters: dielectric absorption ratio (DAR) and polarization index (PI). The first indicates the amount of moisture in the insulation: Drying is required if the volume is high. The second parameter is used to determine the residual insulation life. The megohmmeter also measures AC and DC voltage, has a continuity test function and a timer for resistance measurement mode. The measurement re-sults and operating parameters are displayed on the built-in backlit screen. There are functions for recording data to memory, keeping data on the screen, and determining the minimums and maximums.
The device has a built-in flashlight for working in the dark. The power is supplied from batteries.
