Fluke 1663 Multi Function Tester

Fluke 1663 Multifunction Installation Tester

The Fluke 1663 is a full-featured multifunction installation tester for professional installers, a step above the 1662 in the 1660 series. It verifies fixed wiring to IEC 60364 and local regulations, including the ETCI National Rules for Electrical Installations in Ireland and BS 7671 in the UK, and adds the extra test voltages and RCD modes that specialist and modern installations now demand. Compact and lightweight at under 1.3 kg, it comes with a padded carrying and waist strap and operation simple enough for any skill level.

Supplied by Powerpoint Engineering as an authorised Fluke distributor, the 1663 covers insulation resistance, continuity, loop and line impedance, prospective fault current, earth resistance and RCD testing, with a switchable auto-start and a self-test for faster, more confident results.

What the Fluke 1663 adds over the 1662

• 50 V and 100 V insulation test voltages for telecoms, fire alarm, emergency lighting, intruder alarm and sound systems, and floor conductivity, alongside the standard 250, 500 and 1000 V ranges
• RCD type B and RDC-DD testing in VAR mode (6, 60 and 200 mA plus a ramp test) to IEC 62955, for EV charging station DC protection and 6 mA DC monitors
• TruTest data management software compatibility for storing and reporting results

What the Fluke 1663 tests

• Insulation resistance across multiple test voltages, including 50 V and 100 V
• Continuity of conductors and earth resistance
• Loop and line impedance with prospective fault current
• RCD testing for type A, type AC and type B / RDC-DD, including EV charge point protection

Built for EV and specialist installations

The strongest reason to choose the 1663 is the move to EV charging. Its VAR mode generates the 6 mA DC residual current tests required to verify the DC fault protection built into charge points, following IEC 62955, so you can certify EV installations without a separate adapter for the basic checks. A firmware update extends the 6 mA RDC-DD testing further still, which keeps the instrument current as charge point requirements evolve.

Specifications

Where the 1663 fits in the range

Choose the 1663 over the Fluke 1662 when you test EV charge points, or telecoms, fire and life-safety systems that need 50 V or 100 V insulation testing. The 1662 remains the right choice for straightforward day-to-day certification where those extras are not needed.

FAQs

Can the Fluke 1663 test EV charging points?

Yes. Its VAR mode generates the 6 mA DC residual current tests required to verify the DC fault protection in EV charge points, following IEC 62955, and a firmware update extends the 6 mA RDC-DD testing for evolving charge point requirements.

Why does the Fluke 1663 have 50 V and 100 V insulation tests?

Lower test voltages are required for telecoms, fire alarm, emergency lighting, intruder alarm and sound systems, and for testing the conductivity of floors. The 50 V and 100 V ranges let you test these safely without over-stressing sensitive circuits.

Does the Fluke 1663 need regular calibration?

Yes. To keep results traceable and defensible for certification, calibrate the instrument on a set interval. Our in-house laboratory calibrates and repairs Fluke installation testers and issues traceable certificates.
