Fluke Multifunction Tester, 100mm Length, 125mm Height - FLK-1664FC SCH

This multifunction tester is a handheld installation instrument designed to verify fixed wiring safety in domestic, commercial and industrial settings. It performs insulation, continuity, loop and earth resistance measurements, Plus RCD testing, and interfaces with external systems for data transfer. The unit operates from AA batteries and is rated for use across common site temperatures and indoor environments.

Features and Benefits:

• 1000V insulation tester protecting connected equipment during tests
• 1mA continuity tester delivering up to 2000Ω range accuracy
• Automatic RCD ramp and Type S G AC testing for Rapid verification
• 500V AC/DC voltage multimeter with USB data download capability
• Portable earth resistance meter IP40 for field measurements
• CAT III CAT IV safety category tester for overvoltage environments

Applications

• Suitable for verifying fixed wiring to IEC 60364 standards
• Ideal for testing EV charging RCD A-EV and RDC-DD protections
• Used with smartphones for wireless result sharing and Cloud storage
• Can be used for site acceptance of RCDs and loop impedance
• Useful when documenting results for maintenance and asset records

Which RCD types can it test and how is DC-sensitive testing handled?

It tests AC, A, B/B+, G and S variants and uses a VAR mode to generate smooth DC test currents for DC-sensitive RCDs including EV/RDC-DD devices.

How does the instrument prevent damage to connected appliances during insulation checks?

An insulation pretest detects connected peripherals and halts the insulation measurement while providing Visual and audible warnings.

What interfaces and data options are available for result management?

Results can be transferred via USB or wirelessly to a mobile app and stored in Cloud storage for later processing with compatible data software.

What is the device’s input power and battery arrangement for site use?

It runs on six 1.5V AA cells and provides self-test and illuminated display functions for field operation.

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.
