Figure 19. Earth Resistance Test Connection

To measure earth resistance:

1. Turn the rotary switch to the s position.

2. Press and release T. Wait for the test to complete.

• The primary (upper) display shows the earth resistance reading.

• Voltage detected between the test rods will be displayed in the

secondary display. If greater than 10 V, the test is inhibited.

• If the measurement is too noisy, Err 5 will be displayed. (The

measured value accuracy is degraded by the noise). Press the down

arrow (U) to display the measured value. Press the up arrow (U) to

return to the Err 5 display.

• If the probe resistance is too high, Err 6 is displayed. Probe resistance

may be reduced by driving the test stakes further into the earth or

wetting the earth around the test stakes.
