In addition to the facility for precision measurement, test leads for a simplified two wire measuring system are included as standard accessories.

The latest circuit desgin permits KEW4105A to operate with a minimum influence from earth voltage and earth resistance of the auxiliary earth spikes.

The 2mA measuring current permits earth resistance tests without tripping earth leakage current breakers in the circuit under test.
