Features
- A rugged, compact insulation resistance tester for residential and commercial electricians
- Performs insulation tests from 0.01 to 2000 MΩ
- Offers two insulation test voltages: 500 and 1000 V
- Includes live circuit detection to prevent insulation test if voltage >30 V is detected
- Measures resistance from 0.01 to 20.00 kΩ
- Measures AC/DC voltage from 0.1 to 600 V
- Includes auto-discharge of capacitive voltage for added user protection
- Provides lo-ohms earth-bond continuity (200 mA)
- Simplifies repetitive or hard-to-reach testing with the remote test probe
- Saves battery power with auto power off
- Presents results on a large, backlit display
- Features CAT IV 600 V overvoltage category rating
- Runs on 4 x AA alkaline batteries (NEDA 15 A or IEC LR6) for at least 1000 insulation tests
- Save battery power with auto power off
Applications
- Troubleshooting
- Commissioning
