Kewtech KT66DL Digital 12-in-1 Multifunction Tester

The Kewtech KT66DL 12-in-1 Multifunction Tester has been engineered with pioneering sophisticated loop testing systems, including 3 & 2 wire low current test options and a comprehensive RCD testing facility complete with EV charging point test capacity. The KT66DL has an easy-to-use single rotary dial with four function softkeys and a colour LCD 3.5” dot matrix display. It also incorporates Anti-Trip Technology (ATT) which electronically bypasses RCDs when performing loop impedance tests. This saves time and money by not having to take the RCD out of the circuit during testing and is a safer procedure to follow. With the ATT function enabled, a test of 15mA or less is applied between line & earth. It enables loop impedance measurements without tripping RCDs rated at 30mA and above. ATT supports measurements using three wires: Line, Earth, and Neutral and also two wires: Line and Earth. FEATURES Simultaneous display of L-N, L-N, L-E voltage (TRMS). Three modes of starting a test: single press of the test button, continuous testing and by test button in the test probe. Help display. Advanced memory - assigns DB, circuit no. and type of test i.e. Zs or Ze. Two continuity tests 200mA & 15mA . 55V loop test capability - suitable for 110V CTE systems. Padded neck strap. Supplied with G7 test leads and additional probe incorporating a test button. Tests Type AC, ACS, A, AS, F, B, BS & EV. UC - contact voltage test. Touch voltage pad with selectable limits. Heavy duty canvas carry case with extra room for you testing accessories. The KT66DL has a lid to further protect your instrument. It easily folds under the instrument when in use.
