Chauvin Arnoux CA 6528 [P01140838] Insulation & Continuity Tester, 250V Min, 1000V Max, CAT IV 600 V. The CA 6528 insulation tester is ideal for maintenance and repair operations on electrical equipment such as motors, cables, etc. Thanks to its "hands-free" bag, the CA 6528 insulation tester can be used without any constraints in the field. The shockproof sheath with stand (props) ensure stability on horizontal surfaces. The large LCD screen can show the insulation value and the real test voltage simultaneously thanks to its double display. The backlighting makes it easy to read in all circumstances. The CA 6528 megohmmeter measures resistance, insulation and continuity according to the applicable international standards: IEC 60364, NF C 15-100, VDE 100, etc. The continuity measurement integrates compensation of the cables. Insulation measurement is possible in manual mode, locked mode or programmed-duration mode with the timer. When measuring the voltage, an indicator shows the battery status. The CA 6528 indicates the test results instantaneously: the screen turns red if the threshold is overrun. The presence of a hazardous voltage (>30 V) is detected automatically by the CA 6528, which then prohibits insulation testing.
