  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.
