Selectable insulation test voltages of 50, 100, 250, 500 and 1000V
Polarisation index (PI) and dielectric absorption ratio (DAR) measurements
Variable test voltage from 10V to 1000V
2% test voltage accuracy
PASS/FAIL indication
Stabilised test voltage - feedback controlled to ensure it remains within specification throughout full range
Test voltage display alongside measurements
Analogue arc display replicates response of a moving coil display
Timed testing - automatically test to a time limit
Insulation testing up to 200GΩ (at 1000V)
High quality flexible silicone testleads prevent measurement errors on GΩ ranges
Test inhibit - prevents testing if voltages in excess of 25, 30, 50, 75 ot 100V (set by yser) are detected
Insulation buzzer - can be set to buzz if the insulation resistance is above a user-adjustable limit
