Installation tester

The Fluke 1663 gives you more competence by allowing you to quickly and effectively check whether electrical installations comply with local standards and regulations and protect equipment that may be accidentally connected to systems under test.

Measurement functions

• Passage at entrances LN, N-PE
• Testing of DC-sensitive RCDs/FIs (Type B)
• Earth resistance
• Voltage and frequency
• Polarity tester, detects broken neutral conductors
• Insulation resistance
• Continuity and resistance
• Measure motor windings with continuity testing
• Loop and network impedance
• Expected earth fault current (PEFC/IK)
• Expected short-circuit current (PSC/IK)
• RCD tripping time
• RCD tripping current (ramp test)
• Measures the tripping time and tripping current for RCD type A and AC in a single test.
• Variable test current for RCDs
• Automatic test sequence for residual current devices (RCDs)
• Rotation field direction indicator

Additional functions

• Automatic start, switchable on and off, for RCD and loop impedance measurement
• self-test
• Illuminated display

Storage interface

• Z-max memory
• memory
• PC interface (when used with optional FlukeView and Fluke DMS software)
• Time and date (when used with optional FlukeView software)

Scope of delivery

• Robust mains measuring cable
• hard-shell suitcase
• Probe head with trigger button
• Zero adapter
• Survives a drop from 1 meter high
• Compact, lightweight (less than 1.3 kg), with an additional padded carrying strap that keeps your hands free, making all-day measuring easier.
