EARTH RESISTANCE TESTER

EARTH RESISTANCE TESTER
. Features
•    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.
