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.
● Frequency : 820Hz.
● 0Ω adjustment.
● Battery operated.
● Data hold function.
● Low battery indication.
● Calibration performed with supplied test leads.
● Simplified measurement probe is also provided 
   for two-wire measuring method.
