Page 2: Safety Information
Electronic Digital Earth Resistance Tester is direct replacement of the conventional hand generator type tester. It is designed for measurement of the resistance of earthing used in the electrical equipment as well as for measurement of ground resistivity. It can be used for measurements of the other low regular and liquid resistances. - Page 3 Caution when working with voltages above 60V DC or 30V AC RMS. Such voltages pose a shock hazard. Before taking resistance measurements or testing acoustic continuity, disconnect circuit from main power supply and all loads from the circuit. ...
- Page 4 Auto Power Off: To conserve battery life, the meter will automatically turn off after approx. 15 minutes of non-use. To turn the meter back on, turn the rotary switch to OFF, then to the desired function. Operating Temperature: 0ºC to 40ºC (32ºF to 104ºF) and Humidity below 80% RH Storage Temperature: -10ºC to 60ºC (14ºF to 140ºF)

During operation if the symbol appears on the display, replace the batteries. Short the tips of the leads and press the “TEST” button. Adjust the 0 Ω “ADJ” turncap control to set the reading of zero.
- Page 8 Simplified earth resistance measurement method : This method is recommended where an earth resistance higher than 10 is measured or where it is not possible to drive auxiliary earth spikes. approximate value earth resistance can be obtained by the two wire system where is shown in Fig.
