Kewtech KT63 Multifunction Tester Details

Easy-to-use, compact and made to make testing electrical installations simple, the KT63 is a 5-in-1 multifunction tester with a selection of advanced features.

Featuring loop testing with anti trip technology, the KT63 is suitable for carrying out full, no-tripping loop testing on any RCD type. To maintain accuracy the KT63 will even take into account the effects of electrical noise, filtering it out as necessary.

Insulation testing can be performed on the KT63 with selectable test voltages of 250, 500 and 1000V and measurements up to 999MΩ. When the test is completed an auto discharge will also take place, ensuring the safety of the user at all times. Other functions of this unit include continuity testing, PSC/PFC calculation (displayed at the same time as a loop reading for ease of use) and multiple RCD functions including x ½, x 1, x5, ramp and auto testing.

A number of other additional functions and features are also included such as test lead auto-null when testing continuity, a hands-free mode, rotary dial for testing selection and an instant correct wiring status check to ensure testing is carried out safely and accurately.

The KT63 is compliant with BS7671 (Part P) regulations.
