Detail

 

FEATURES
● High quality Taut Band movement.
● Capable of measuring earth resistance and earth voltage. 
● 2mA measuring current permits the testing of earth
   resistance without tripping earth leakage current
   breakers in the circuit under test.
● Test leads are supplied as standard accessories
    for simplified two-wire measuring system.
● Battery operated.
● Battery check function. 
● Calibration performed with supplied test leads.
