• 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. 4102A Soft Case Model 4102A-H Hard Case Model
