•

The latest circuit design permits the instrument to operate with the minimum of influence from earth voltage and earth resistance of auxiliary earth spikes.

•

Dust and drip proof. (designed to IEC 529 IP54)

•

Earth resistance value can be read directly from the scale.

•

Designed to meet IEC 61010-1 safety standard.

•

Capable of measuring earth voltage.

•

Small and lightweight. Shock resistant new case material.

•

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

•

Lead wire connection to C and P terminals and proper auxiliary earth resistance can be checked by "OK" lamp. Lead wire connection to C and E terminals is good when "OK" lamp is illuminated.
