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

This multifunction tester is a portable electrical installation instrument designed for routine and diagnostic fieldwork in industrial and commercial environments. It performs essential measurements such as voltage, frequency, insulation resistance up to 1000V, earth resistance and loop impedance, and includes RCD testing modes to assess protective device performance. The unit is battery powered and offers a USB Interface for data transfer, suited to technicians working across automation, electronics, electrical and mechanical disciplines.

Features & Benefits

• Insulation test up to 1000V for high-voltage verification and safety assessment
• Continuity measurement with 1 mA test current for sensitive circuit checks
• RCD ramp and automatic sequences to determine trip level and timing
• Loop impedance phase to earth and phase to NEUTRAL for fault current calculation
• Prospective fault current computation to estimate PEFC/PSC values
• USB downloadable data for job reporting and traceable records

Applications

• Suitable for verifying wiring polarity and identifying broken NEUTRAL conductors
• Ideal for commissioning and periodic inspection of distribution circuits
• Used for testing RCD Type S, Type G and AC devices in installations
• Can be used to evaluate motor winding continuity during maintenance
• Used with site reports where earth resistance measurement and loop values are required

What supply does it use and how long is the instrument sealed against dust?

It runs on six AA cells and has IP40 sealing for indoor use where protection from large particles is required.

Which overvoltage categories does it support for on-site measurements?

The instrument meets CAT IV 300V and CAT III 500V overvoltage classifications for common installation environments.

How are RCD tripping characteristics measured during testing?

It performs tripping speed measurements and variable-current ramp tests across a range of currents with defined dwell times to establish trip current and timing.

Can it measure both insulation and loop resistance for fault calculations?

Yes, it combines insulation resistance measurements with loop and line impedance readings to compute prospective earth fault and short-circuit currents.

What accessory and data support is provided for field reporting?

The package includes a remote control probe and leads, a zero adapter for lead compensation, and downloadable results via USB for documentation.
