1. Turn the rotary switch to the
position.
2. Press and release
. 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 (
) to display the measured value.
Press the up arrow (
) 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.

1. Turn the rotary switch to the
position.
2. The primary (upper) display shows:
•123 for correct phase sequence.
•321 for reversed phase sequence.
•Dashes (---) instead of numbers if insufficient voltage is sensed.
