Features/Benefits
-
- * Replaces canceled 9U-6003 Insulation Tester.
- * Used to measure and check insulation resistance for electrical power generation.
- * Separate voltmeter range operates from 0 to 600 VDC at 50/60 Hz and to 450 VDC at 400 Hz.

- * Meter ranges from 100 kW digital and 10 MW analog to test for faults on motors, generators, or relays.
- * Tool defaults to voltmeter operation whenever an external voltage greater than 25 VDC or VAC is detected (only exception is when meter is off or preforming battery condition test).
- * Auto shut-off feature turns an unused unit off after 5 minutes.
- * Display includes solid state analog arc .
- * Battery condition test position measures voltage on a simulated load.
- * Operates at temperatures from -20°C to +40°C (-4.0°F to 104.0°F)
- * Case is weather and dust proof.
- * Replaces canceled 9U-6003 Insulation Tester.
