The Fluke 1663 multifunction installation tester is used to verify the safety of electrical installations in domestic, commercial and industrial applications. The 1663 puts comprehensive testing power in your hands, quickly and efficiently ensuring that fixed wiring is correctly installed to meet the requirements of IEC 60364 and all relevant local standards, protecting workers as well as appliances connected to the system under test.

The Fluke 1663 is the ideal tester for professional trouble-shooters. This instrument delivers high-end functionality and advanced measurement capability, while remaining intuitive and easy to use for all levels of field workers. The 1663 has a comprehensive range of measurement functions including: TRMS AC/DC voltage and frequency measurement, wiring polarity checker (detects broken PE and N wires), insulation resistance, continuity at L-N, L-PE, N-PE inputs, testing smooth DC sensitive RCDs (Type B/B+), earth resistance, continuity and resistance measurement, motor winding continuity testing, loop and line resistance, prospective earth fault current (PEFC/IK), prospective short-circuit current (PSC/IK), RCD trip time, RCD trip current (ramp test), simultaneous trip time and current measurement for RCD type A and AC, variable RCD test current, automatic RCD test sequence, and phase sequence test. This provides users all the testing power needed for comprehensive electrical installation testing.

Designed with Fluke's legendary reliability and simple operation, the 1663 includes an Auto Test function that performs five required installation tests in one automated sequence, including selectable Type A, AC & RCD Auto Test, ensuring compliance with local installation regulations. This reduces the number of manual connections, the risk of user error, and overall test time.
