    • In addition to the facility for precision measurement, test leads for simplified two wire measuring system also supplied as standard accessories.
    (unit can be hung from the neck for simplified measurement)
    • 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 60529 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.
