Fluke 1650B series installation tester

Click2Contact

The 1650B series installation tester provides two measurements at once and a dual display. PEFC/PSC and loop impedance are measured and displayed in parallel, which is claimed to save more than 50% of test time compared to other loop testers.

The series features an additional high current loop mode and faster measurements compared to loop tests with non-trip mode for RCDs. The tester has a zero adapter for fast, reliable and accurate test lead and mains cord compensation and enables fast voltage measurement between L-N, L-PE and N-PE using the mains cord. There is no need to change measurement connections.

The earth volt touchpad detects raised earth voltages >50 V, indicating potential dangerous situations. The tester is supplied with the SureGrip test leads and clips which give the user a comfortable, reliable grip.

The rotary dial knob indicates which function is selected, all functionalities on one spot and no complex multilevel menus. The tester features a large display with backlight, clear symbols and a wide viewing angle for easy and safe readings; pass/fail indication for RCD test results; and variable RCD current mode for customised settings.

The tester withstands a drop from 1 m and is compact and lightweight (<1.3 kg) with a padded neck strap.
