“WATTS CURRENT” TECHNICAL BULLETIN

To enable the instrument to accurately calculate soil resistivity, we must enter the electrode
spacing distance. We start by ensuring the instrument is configured for the correct units of
measure. Turn the instrument’s dial to the set-up setting. Then press the DISPLAY button. The unit
of measure, either meters (m) or feet (ft), appears blinking on the screen. Pressing the Up button
toggles between these two options. In our example we’re using feet, so if this is set to meters
press the Up button to change this setting.
Next, turn the dial to the 4-pole
ρ
setting. To enter the spacing distance, press the yellow button
labeled 2nd. The symbol 2nd appears on the screen, indicating buttons will now perform the
actions labeled in yellow.
Press the DISTANCE button. The word DISTANCE appears on the screen, and the first digit in the
distance field blinks, indicating it is in edit mode. Use the Up and Right buttons to navigate through
this field and make selections. For example, to set the distance to 10 feet, press the Right button
to navigate to the second digit and press the Up button to change this to 1. The field should now
be set to 10 feet.
