You can save the setting by pressing the yellow 2nd button to enter 2nd mode and then pressing

the DISTANCE button.

You are now ready to take a soil resistivity measurement. To do this, push the START/STOP button

and hold it down for at least two seconds. After a few moments, the resistivity reading appears,

displayed in ohm-meters. The resistance of the soil between the two potential electrodes is also

displayed, in ohms.

To save the measurement in the instrument’s memory, press the MEM button twice. This saves

the reading, along with the date and time the reading was taken. This stored record can later be

displayed on the instrument’s screen, and downloaded to a computer using DataView

for further

analysis.

This concludes our quick explanation of how to perform a Wenner soil resistivity measurement with

the Model 6472. For more information about this instrument, please visit our
