FEATURES
● 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.
● In addition to facilitating for precision measurement, 
   test leads for simplified two-wire measuring system 
   also are supplied as standard accessories.
● Battery operated.
● Battery life indicator.   
● Calibration performed with supplied test leads.
