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


This multifunction tester is a portable instrument for verifying electrical installations and protective devices across industrial and commercial environments. It combines insulation, continuity, loop impedance and RCD testing with live data transfer to mobile devices, enabling on-site measurement capture and reporting while working to national installation practices.

Features & Benefits


• Insulation test up to 1000V protects connected equipment from damage
• Continuity test current of 1 mA allows safe motor winding checks
• Loop impedance phase to NEUTRAL tester provides Rapid ZI and PSC readings
• RCD ramp test meter Fluke supports VAR mode for EV/DC RCDs
• Earth resistance measurement tester outputs 25V at 128 Hz for RE checks
• Downloadable data USB tester syncs results to smartphone/cloud

Applications


• Suitable for commissioning domestic and commercial distribution boards
• Ideal for testing EV charging DC protection and 6 mA monitors
• Used for maintenance diagnostics on motor windings and circuits
• Can be used for field data collection and report generation via cloud
• Used with site acceptance procedures requiring RCD trip and timing checks

What power source does it use and how many cells are required?


It runs on six AA batteries, enabling field use without mains power.

Which overvoltage categories does it meet for safe measurement environments?


It is rated for CAT III at 500V and CAT IV at 300V for site testing.

How does it handle non‑trip RCD loop tests for Faster readings?


It offers a high‑current loop mode and a Z‑max memory to capture Peak loop values without tripping protective devices.

Can it measure prospective fault current and how is that calculated?


It computes PEFC or PSC by dividing measured mains voltage by loop or line resistance and displays the Value in amps.

What interfaces are available for exporting results and remote control?


It includes a USB Interface for data download and a remote probe/lead for switch‑mode operation.
