(e.g. The spike should be stuck in the depth of 25cm or less when the

interval of the Auxiliary Earth Spikes is 5m.)

If the Spikes stuck too deep, it may result in inaccurate earth resistivity

measurement.

Note) The supplied Test Leads MODEL 7229 can be used for the Spikes

stuck at the interval of max 20m.

Note) The length of the supplied Auxiliary Earth Spike MODEL 8032 is

20cm.

Connect the green, black, yellow Test Leads connected to the “E”, “ES”,

“S(P)” and “H(C)” Terminals on the instrument to the Auxiliary Earth Spikes

from the closest to the farthest in this order. (Fig.41)

(3) Setting of the Interval between Auxiliary Earth Spikes
The interval of the Spikes should be entered according to the setting

made at the step of “8-2-5 Setting for the interval between Auxiliary

Earth Spikes at Earth Resistivity (ρ) Measurements”.

(4) Earth Resistivity (ρ) Measurement
Select a Range (any Range is ok) when the connection is done, and

press the TEST Button. Then the measured earth resistivity (ρ) and
the earth resistance “Rg” between the ES-S Terminals are displayed.
