Insulation Tester Plus

The Insulation Tester Plus (61-790C) is built for electrical professionals who need to verify complex wiring installations faster with clear, reportable results. By connecting the megohmmeter to the free Electrician’s Sidekick app, users can remotely control the meter, view live graphs, and share inspection-ready reports at a safe distance straight from their phone. The insulation resistance tester’s unique, color-coded display also lights up green or red for instant pass/fail test results at a glance. Rated CAT III 1000V / CAT IV 600V with TRMS, this device makes verifying installations easy across five voltage test ranges from 50-1000V. The 3-in-1 Insulation Tester Plus also tests low-ohm applications like grounding systems and functions as a multimeter with continuity testing, diode testing, and more. Say goodbye to tedious, handwritten results and hello to digital, easy-to-share reports with the Insulation Tester Plus.

• 3-IN-1 TESTING AND TROUBLESHOOTING TOOL: Combines DAR/PI insulation resistance tests across five voltage test ranges (50V, 100V, 250V, 500V, and 1000V), low-ohm bonding checks, and multimeter capability for an all-in-one solution
• CONTROL TESTS FROM A DISTANCE: Start, monitor, and manage tests from a safe distance on your phone using the megohmmeter’s Bluetooth compatibility, including from outside the arc-flash boundary or through a closed cabinet door
• INSPECTION-READY DIGITAL REPORTS: Say goodbye to handwriting results and keeping track of paper reports—the mobile app automatically logs tests and organizes results into clean CSV or PDF files that are ready to share with inspectors or general contractors
• HEAR LIVE RESULTS ALOUD: An optional app voice-over continuously reads out live test data every few seconds, so you can keep your eyes and your hands on the test leads rather than the display
• INTERPRET RESULTS IN AN INSTANT: In compare mode, the color-coded display lights up green or red to indicate pass/fail insulation test results at a glance
• TROUBLESHOOT WITH FEWER TOOLS: Leave the extra meter behind with built-in multimeter functionality, including an audible continuity test, diode test, capacitance, resistance measurement, and AC/DC voltage (0-1000V)
• READY FOR LOW-OHM TESTING: Supports low-resistance testing with 50,000 count display, helping verify grounding systems, motor windings, and other applications where standard testing may overlook issues
• CONVENIENT REMOTE PROBE: A separate, handheld probe allows you to start and control insulation tests directly at the point of contact without letting go of the leads
