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.
