Battery operated tester for the measurement of ground resistance meets international standards for performing such tests. This instrument allows measurement of soil resistivity and ohmic resistance by means of the ammeter-voltmeter test method.

   - 3 or 4-wire measurement selectable from menu

   - No balancing required

   - Indication is displayed if maximum probe resistance is exceeded at the beginning of the measurement

   - Voltage measurement with automatic switch-over function
between direct voltage and alternating voltage

   - Direct voltage measuring range 1-250V

   - Alternating voltage measuring range 0-300V
