B Connect test leads.
Connect terminals E/C1 and ES/P1 with the supplied safety test leads
(1.5 m) to the earth electrode to be measured. Place 2 ground stakes
in earth/dirt. Minimum distance between earth electrode (E/C1),
probe (S/P2) and auxiliary earth (H/C2) should be at least 20 m! The
ES test lead eliminates the influence of the test leads.
Connect stakes with 25 m and 50 m wires to H/C2 and S/P2 as
shown.
Connect current clamp with adapter cable as shown.
C Press START.
The “active” symbol indicates that measurement is in progress. For
continuous measurement keep START pressed.
D Symbol “9” indicates completed measurement. The result is kept on
display until a new measurement is started or the rotary switch is
turned.
