| 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.
