COMPREHENSIVE TESTING FEATURES - Comprehensive 16th edition and Part-P testing features allow for a multitude of tests including: Earth Continuity, Insulation (100v, 250v, 500v), Non-trip Loop Impedance, Line Impedance, RCD Trip current, and Voltage/Frequency measurement.
UNIQUE CORDLESS PROBE - Makes testing a breeze as it allows you a free hand to hold your tester - therefore you can view your results, as you’re testing.
NON-TRIPPING LOOP - Measure loop impedance without tripping RCD’s.
SMALLEST AND LIGHTEST IN ITS CLASS - It fits in the palm of your hand and won’t weigh you down.
