They each also offer the capability of delivering up to 17 different functions, all of which can be selected using a rotary switch on the front panel, meaning the testers can be conveniently operated when wearing safety gloves.
Suitable for use with any type of neutral system (TT, TN, IT), the testers have coloured terminals to cut down on connection errors and provide resistance, continuity, insulation, earth, loop impedance, current, voltage and frequency measurements.
The units are also ideal for type-A and AC RCD testing and phase rotation/sequence tests, with resolution for loop measurement of 1mΩ. The C.A 6117, which has a built-in fuse table for rapid results estimates, is capable of type-B RCD testing and voltage drop ΔV% measurement.
The C.A 6116N and the C.A 6117 feature colour displays with multi-lingual contextual help and are powered by Lithium-Ion batteries to offer extended operational life.
