Kewtech KT63DL 18th Edition Multifunction Tester

The Kewtech KT63DL is one of the bestselling entry-level 18th edition multifunction testers on the market and is ideal for domestic electricians looking for a very easy-to-use and affordable tester.

Designed for frequent use, the Kewtech KT63DL is housed in a robust enclosure and is IP54 rated, even when the leads are not plugged in. It features a single rotary dial from which the user can select test ranges for loop, continuity, insulation and RCD testing. The KT63DL also features auto-testing of the most commonly found 30mA RCD types, preventing the user having to return to the tester when the RCD trips.

This 5 in 1 tester features a large backlit display, for easy visibility even in poor lighting, along with a soft carry case for protecting and transporting the unit and its accessories. Essential accessories include the Kewtech KAMP 13A mains lead, ACC063 3 wire distribution board test lead set, batteries and manufacturers end of line calibration certificate, all of which are included with the KT63DL.

All tests can be carried out using the hands-free function. Simply turn the dial to the test required and push the HANDSFREE button. The test will automatically start once the leads are connected.

Kewtech KT63 vs KT63DL. What are the differences?

The KT63DL can test type A & AS RCDs, as wells as including a 10mA RCD test. All other features are the same, the multifunction tester still retains the easy to use interface that so many professional electricians are familiar with.

How to upgrade Kewtech KT63 to KT63DL

You can send your KT63 to Kewtech at any time to get it upgraded to the KT63DL. Contact Kewtech for pricing and availability. You upgrade will include a new calibration certificate. 

Loop testing
This Kewtech MFT features anti trip technology for full no trip loop impedance testing of RCD of all types (AC & ACS). The Prospective Fault Current (PFC) and Prospective Short Circuit (PSC) results are also record at the same time the loop test is carried out and can be displayed by pressing the PFC-LOOP button.

Continuity testing
Auto ranging 200mA. The multifunction is also protected against accidental connection to live circuits, thanks to continuous live monitoring, and will alert the user accordingly. The test will be inhibited by the unit until no voltage is present. The test leads auto null for continuity mode to ensure fast and reliable readings. You can also use the KT63DL in conjunction with the Kewtech PAT ADAPTOR1 (available separately) to carry out dead PAT testing.

Insulation testing
With selectable ranges of 250V, 500V and 1000V, the KT63DL is suitable for dead and live testing. Simply rotate the dial to the required voltage. Again this unit can be used in conjunction with the PAT ADAPTOR1 for insulation testing of portable appliances.

RCD testing
The Kewtech KT63DL can test AC type 30mA / 100mA / 300mA and 500mA RCD’s, with a handy auto test for 30mA. A ramp test feature is available at ½, x1 and x5. 100mA and 300mA ACS type RCD types can also be tested. The updated DL version now tests type A & AS RCDs using the same easy to use interface. 10mA RCD tests have also been added.
