Test AC/DC voltages from 12 to 690V with the Di-Log DL6780 Voltage Indicator. This tester features a CAT IV 600V safety rating for enhanced protection. It offers continuity testing with both optical and acoustic indications, and automatically switches between voltage and continuity modes for seamless operation. The integrated phase rotation test system allows verification of three-phase systems, and single pole detection quickly identifies voltage presence. Fully compliant with GS38 standards, it provides full voltage indication even with discharged batteries and is designed not to trip RCDs during testing. Meets safety and performance requirements of BS EN 61243-3 2014.
