Key Features
• Safety first – Connect the insulation tester and monitor test measurements remotely to keep yourself out of harm’s way.
• Wireless result sharing – Quickly view and share insulation resistance test results with your smartphone using Fluke Connect.
• Measurement comparison – Save measurements and compare results over time to quickly identify developing problems.
• PI/DAR timed ratio testing – Includes TrendIt™ graphs to help identify moisture and contaminated insulation faster.
• Automatic data storage – Store measurements directly to your smartphone or cloud, eliminating the need to write down results.
• Temperature compensation – Establish accurate baselines and perform reliable historical comparisons.
• Live circuit detection – Prevents insulation testing if voltage greater than 30 V is detected.
• VFD low-pass filter – Ensures accurate measurements on variable frequency motor drives.
• Automatic capacitive voltage discharge – Provides additional protection for the user during testing.
• Multiple measurement functions – Measures AC/DC voltage, DC millivolts, AC/DC milliamps, resistance, continuity, capacitance, diode, temperature, frequency, and insulation resistance.
