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


This multifunction tester is a portable electrical installation instrument for verifying wiring, insulation and protective device performance on-site. It connects via a single lead for automated test sequences, supports wireless result transfer to smartphones, and is designed for field use across a range of ambient conditions.

Features & Benefits


• Insulation tester 1000V Fluke with pre-test protects connected appliances
• Continuity tester 1mA Fluke for low-current winding checks
• Loop impedance phase to earth tester with high-current mode for Faster reads
• RCD ramp test capability for precise trip-characteristic evaluation
• Earth resistance measurement tester operating at 128Hz with 25V output
• Fluke multifunction tester battery AA 200h runtime with replaceable cells

**Applications**


• Suitable for periodic installation verification to local regulations
• Ideal for testing EV charging station DC protection devices
• Used for commissioning RCD AC Type S Type G tester functions
• Can be used for prospective earth fault current and PSC measurements
• Used with site reporting workflows via USB downloadable and smartphone sync

How does it prevent damage to appliances during insulation tests?


An insulation pre-test detects connected equipment and halts the insulation measurement while giving a Visual warning.

What RCD types and specialised modes are supported for charging stations?


It tests AC, Type S and Type G RCDs, and provides a VAR mode that generates 6/60/200mA smooth DC pulses for A‑EV/RDC‑DD verification.

How are results recorded and shared on-site?


Measurements may be transferred via a USB downloadable Interface or wirelessly to a smartphone for Cloud storage and live sharing.

What safety categories and maximum voltage does it handle?


The instrument meets CAT III/CAT IV application levels and measures up to 500V AC/DC.
