FLUKE FLK-1662 SCH installatietester (4546944)

Verifying the safety of electrical installations demands precise, repeatable measurements across continuity, insulation, loop impedance, and RCD protection. The FLUKE FLK-1662 SCH Installation Tester delivers those measurements in a single, rugged instrument built for daily use by electricians and inspectors.

Who is it for

Electricians, electrical contractors, and safety inspectors who must certify residential, commercial, or industrial installations to local wiring regulations. It suits professionals who need a dependable, all-in-one tester that reduces rework and speeds up reporting.

Main features

• Measures continuity, insulation resistance, loop and line impedance, RCD trip time and current, phase sequence, voltage, frequency, and PEFC/PSC.
• Insulation test voltages of 50 V, 100 V, 250 V, 500 V, and 1000 V with resistance range up to 1000 MΩ depending on voltage.
• Continuity testing with >200 mA test current and range from 0.01 Ω to 2000 Ω.
• Loop impedance measurement from 0.01 Ω to 2000 Ω.
• Supports RCD types AC, A, B, B+, and F (general and selective) with test currents of 10, 30, 100, 300, 500, and 1000 mA.
• Voltage measurement from 50 V to 500 V AC/DC and frequency from 45 Hz to 65 Hz.
• Backlit LCD display for clear readings in dim environments.
• Auto test sequence for RCD and insulation testing.
• Phase sequence indication and test lead compensation for continuity and resistance.
• Powered by 6 AA (IEC LR6) batteries.
