To measure earth resistance:
1. Turn the rotary switch to the
2. Press and release
• 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 (
Press the up arrow (
• 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.
