Fluke 1662 — Multifunction installation tester
For insulation, protective conductors, loop/line impedance, phase sequence and RCD tests. Insulation test voltage and permitted input voltage are different specifications. The base installation-testing model; insulation tests start at 100 V.
- AC voltage: ≤500 V
- Insulation test voltage: 100 / 250 / 500 / 1000 V
- Insulation resistance: Up to 1000 MΩ at 1000 V test
- Protective conductor continuity: 20 / 200 / 2000 Ω
- Loop and line impedance testing: Yes
