T.I.S Calibration Checkbox Loop RCD IR Continuity Checks 1000V 30mA (TISCHECKBOX)
T.I.S TISCHECKBOX is a calibration checkbox designed to check tester accuracy for continuity at 0.50, 5.00 and 10.00, insulation resistance at 1.00M, 50.0M and 200M up to 1000V, RCD tests at 30mA x1 and 30mA x5 with defined trip-time targets, plus loop impedance verification using Local loop and added values of +0.50, +2.00 and +50.0, and an AC voltage check output for 0€“250V confirmation. For Green2Go, it supports efficient, sustainability-focused servicing by helping reduce repeat visits caused by questionable readings, improving reliability of test workflows across renewable and EV charging maintenance.
