    Kewtech KT63 Plus 6 in 1 Multifunction Tester

    The Kewtech KT63 Plus 6 in 1 Multifunction Tester is an exceptionally uncomplicated 18th edition testing device, harnessing the versatility of a multifunction tester in conjunction with a tactile user interface. The KT63 Plus can perform a formidable array of tests, such as:

    • 250 / 500 / 1000V insulation test with auto discharge
    • RCD tests AC/A & ACS/AS
    • Phase Rotation
    • Special DNO mains polarity test

    Utilise the KT63's impressive new anti-trip loop technology for full no-trip loop testing on all electronic and electro-mechanical RCDs of 30mA and above. With very low susceptibility to RCD uplift or noise interference, confidently attain accurate results without disruption. The auto-null facility allows for accurate continuity measurements (test lead resistance is 'remembered' by the instrument), whilst 10, 30, 100, 300, 500 and 1000mA RCDs can be tested at 0.5x 1x and 5x across 0º and 180º polarities. 

    There are three ways to commence testing with the KT63 Plus, a single press of the test button, continuous testing through handsfree use of the test button, or by utilising the test button in a test probe. A continuous live monitoring function prevents damage to the tester and PFC / PSC measurements are made easy as there is no need to alter the test probes. Notably, these PFC / PSC results are displayed to the user in real time alongside the loop readings. 

    The sizeable backlit, full colour screen of the KT63 Plus is extremely useful when operating the UK specific RCD test as it is able to display all six results at once without the need for scrolling. Boasting an easy to use single rotary dial with four secondary function keys, this IP54 rated instrument fully compliant with BS7671 regulations, makes function selection and the reading of multi-test results as simple as possible.
