Fluke Multifunction Tester, 500V Maximum Voltage Measurement, 1000V Insulation Test Voltage - FLK-1664FC DE

This multifunction tester provides essential installation diagnostics for electricians and engineers working in automation, electronics and mechanical environments. It performs insulation, continuity, loop and RCD assessments alongside voltage and frequency checks, offering a compact, battery-powered instrument for on-site verification and fault analysis.

Features & Benefits

• Insulation tester 1000V delivers up to 1000V for insulation measurement and high-resistance detection
• Portable continuity tester 1mA uses 1mA test current for sensitive conductor checks
• Loop impedance tester phase to earth offers L-PE and L-N loop assessment for PSC/PEFC calculation
• RCD ramp test tester performs stepped ramp tests from 30% to 110% of rated current
• Multifunction electrician tester 500V measures AC/DC voltages to 500V with 0.8% accuracy
• CAT IV 300V CAT III 500V tester provides overvoltage protection for varied installation tiers

Applications

• Suitable for commissioning and periodic inspection of electrical installations
• Ideal for motor winding continuity and resistance verification
• Used for on-site RCD performance validation including tripping time measurement
• Can be used for calculating prospective earth fault and short-circuit currents
• Used with distribution boards for wiring polarity and phase-sequence checks

How is data exported for reporting and analysis?

The instrument includes a USB Interface enabling downloadable data transfer to a PC for Record keeping and post-test review.

What power source and battery life provisions are used for fieldwork?

It operates from six AA batteries, supporting portable use without mains power and simplifying battery replacement.

Which RCD types and test modes are supported during protection verification?

The tester exercises Type A, AC, G and S RCDs, providing variable current, tripping time and ramp-step measurements for each type.

How does it compensate for test leads and mains cord resistance?

A dedicated zero adaptor and lead compensation routine allow accurate loop and continuity results by offsetting lead and cord influences.

What environmental sealing and safety standards does it meet?

The unit has IP40 ingress protection and complies with EN/IEC 61010 series and EN 61557 performance requirements.
