Fluke 1651B: The everyday tester, for every electrical installer The everyday tester ideal for the domestic covering all the basic needs for testing to the 17th Edition wiring regs / Part P of the building regulations. Fluke 1652B: The ideal tester for professional trouble-shooters Due to its additional functionality the Fluke 1652B is the ideal tester for professional trouble-shooters working in both domestic and commercial. Although packed with advanced features the 1652 is easy to through its intuitive user interface. Fluke 1653B: The complete tester for advanced users The complete tester for virtually all electrical wiring installations - domestic, commercial or industrial. This is the instrument that has it all, all the test functions you need (including phase rotation test) to in-built memory for documenting results. The Fluke 1653B makes it the complete solution for professionals who need to have the best tool available.

Safer, easier installation testing.

The 1650B Series testers verify the safety of electrical installations in domestic, commercial and industrial applications. They can ensure that fixed wiring is safe and correctly installed to meet the requirements of IEC 60364, HD 384 and all relevant local standards

Faster

Two measurements at once and a dual display. PEFC/PSC and loop impedance are measured and displayed in parallel, saves you more than 50% of test time compared to other loop testers. Additional new high current loop mode. Faster measurements compared to loop tests with non-trip mode for RCD’s. Unique zero adapter for fast, always reliable and accurate test lead and mains cord compensation. Fast voltage measurement between L-N, L-PE and N-PE using the mains cord. No need to change measurement connections.

Safer

Earth Volt Touchpad detects raised earth voltages >50 V, indicating potential dangerous situations. Standard supplied with fused test leads to comply with GS38.

Easy

Rotary dial knob indicates clear which function is selected, all functionalities on one spot and no complex multi level menus. Large display with backlight, clear symbols and with exceptionally wide viewing angle for easy and safe readings. PASS/FAIL indication for RCD test results. Variable RCD current mode for customized settings.

Rugged & lightweight

Withstands a drop of 1 meter. Compact, lightweight (less than 1.2 kg) and padded neck-strap to free your hands for all day testing.

	Complete kit All 1650B models are equipped with detachable leads that can be replaced in case of damage or loss. A durable hard case will protect your instrument in tough field conditions.
	Slim probe design with test button Keeps your eyes on the panel while probing hard to reach points. This remote probe is powered by the tester so always operable (does not require additional batteries).
	Zero Adapter For easy, always reliable and accurate compensation of test leads and mains cords. This adapter can be used for all different kind of mains plugs as well as test accessories like probes, alligator clips etc.
