Figure 6. 3-Pole/4-Pole Measurement of Single Earth Electrode Resistances
A flashing of the sockets symbols  or , points to an incorrect or incomplete
connection of the measuring lead.
Fix clip-on transformer around the earth electrode to be measured.
Make sure that the clip-on transformation ratio set on the instrument corresponds to the
clip-on transformer used. Change settings if necessary (see How to Change All Data
Settings with Personalized Code).
Note
The ratio that is preset from factory is correct for the EI162X sensing clamp.
