Operating Instructions

XW Warning

To avoid possible electric shock or personal injury, before

powering up and operating the device, carefully read and

follow all safety regulations described in “Safety

Regulations.”

3-Pole Measurement

To perform a 3-pole measurement:

1. Insert the probe and auxiliary electrode stakes into the soil as shown

in Figure 4. Ensure the probe stake is a minimum distance of 20 m

(64 ft) from the earth ground electrode. Ensure the auxiliary electrode

stake is a minimum distance of 20 m (64 ft) from the probe stake.

Position the auxiliary electrode stake so it forms a straight line with

the earth ground electrode and probe stake.

2. Set the rotary switch to OFF.

3. Install the test leads as shown in Figure 4. Connect the earth ground

electrode to jack E/C1. Connect the probe to jack S/P2. Connect the

auxiliary electrode to jack H/C2.

4. Set the rotary switch to 3 pole and press START. The ACTIVE icon

displays to indicate that the measurement is in progress.

When the measurement is finished, the earth ground electrode

resistance (R

E) automatically displays. To display the auxiliary

electrode resistance (R

H), press DISPLAY. To display the probe

resistance (R

S), press DISPLAY again.
