Description
Overview
The Kyoritsu KEW 4105A-H is a portable digital earth (ground) resistance tester used to verify the integrity of earthing systems in electrical installations, substations and lightning-protection systems. Its large LCD gives a clear direct reading, and an IP54-rated, dust- and drip-proof housing makes it dependable outdoors. The “-H” denotes the hard-case model, supplied in a protective carrying case for extra durability (a soft-case version is also available).
The KEW 4105A-H measures earth resistance on 20 Ω, 200 Ω and 2000 Ω ranges (0.00 to 1999 Ω) using the 3-pole or 2-pole fall-of-potential method with auxiliary earth spikes, and also measures earth voltage from 0 to 200 V AC. A low 2 mA test current lets measurements be made without tripping earth-leakage breakers. It is rated CAT III 300 V and powered by six AA batteries in a compact 550 g package.
