• Dust and drip proof.(designed to IEC 529 IP54) • 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) • Designed to meet IEC 61010-1 safety standard. • Capable of measuring earth voltage. • Automatic warning when resistance of auxiliary earth spikes is in excess of tolerance. • 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. 4105A Soft Case Model 4105A-H Hard Case Model
