200GΩ Megohmmeter Digital Insulation Tester Test 500V/1kV/2.5kV/5kV Voltage
Product Information
About
【5kV Auto-Ranging Megohmmeter】Measures insulation resistance from 1MΩ to 200GΩ with selectable test voltages of 500V/1000V/2500V/5000V (output maintained at 90%~110% of rated value). Features 3-1/2 digit 1999-count auto-ranging LCD with automatic polarity and over-range indication. Built-in AC voltmeter: 1V–750V, 40–400Hz, ±(2%+5digits).
【Guard Terminal for Precision Testing】Equipped with a dedicated GUARD (COM) terminal and small alligator clip to eliminate surface leakage current—critical for accurate readings on contaminated or humid surfaces. Improves stability when testing transformers, motors, cables, and high-voltage switches.
【Rugged Outdoor-Ready Design】Shockproof, dustproof, and moisture-proof structure with protective rubber case for harsh job sites. Complies with IEC-1010 double insulation, overvoltage category II, pollution degree 2. HV red LED warning light illuminates during high-voltage output; internal protection circuit prevents damage from back EMF.
【High Load Capacity & Easy Operation】Strong load drive with approximately 1mA short-circuit output current for reliable testing of large capacitive equipment. One-touch TEST/STOP control, rotary voltage selection, and large backlit LCD with data hold. Battery-powered (6× AA included)—no hand-cranking required
【Complete Kit】Includes AP-6688B insulation resistance tester, 2× test leads, 1× shoulder strap, 6× 1.5V AA batteries, 1× small screwdriver, and English user manual. Ready for electrical maintenance, HVAC, motors, cables, and home improvement use.
