Irfora Insulation Resistance Tester Digital Meter Resistance Vole Polarization Index DAR Measuring Meter LCD Display with Back

polarization index (PI), absorption ratio (DAR). This can be widely used for measuring transformers, motors, cables and so on. If you are looking for this product, come and have a try! 100 Group Data Storage: After measuring the insulation resistance value, press HOLD button to keep the data first, and the screen will appear "HOLD" , and then press READ button to save the data. Absorption Ratio (DAR): Determine whether the equipment is affected by the dampness of the insulation resistance measurement Instrument programming defaults for calculating DAR with insulation resistance values at 15 seconds and 60 seconds. Polarization Index (PI): PI measurement is used to identify the aging of insulation quality. The insulation resistance value at 1 and 10 minutes is used to calculate PI. Wide Applications: This is suitable for measuring insulation resistance of transformers, motors, cables, switches, electrical appliances and other electrical equipment and insulation materials. Suitable for various electrical equipment maintenance, s, test and verification.
