 	<li>Measures earth ground resistance - 3 point (fall of potential) or 2 point tests</li>
 	<li>Automatically calculates resistivity - 4 point test</li>
 	<li>Automatic voltage measurement prevents false measurements</li>
 	<li>Automatically applies three testing frequencies for the most accurate readings</li>
 	<li>Test leads, auxiliary electrodes and software are included for complete instrument</li>
 	<li>Auto ranging</li>
 	<li>999 internal memory locations to store measurements</li>
 	<li>RS-232 download to a personal computer</li>
