Figure 9.
1.Turn central rotary switch to position "RE 3pole" or "RE 4pole"
The instrument is to be wired according to picture and notices given on the display.
A flashing of the sockets symbols EFGHor A, points to an incorrect or incomplete connection of the measuring lead.
2.Press "START TEST" button
Now a fully automated test sequence of all relevant parameters like auxiliary earth electrode, probe- and earth electrode resistance, is im- plemented and finished with the display of the result RE.
3.Read out measured value RE
4.Call RS and RH with "DISPLAY MENU".
Remarks for the setting of earth spikes:
Before setting the earth spikes for probe and auxiliary earth electrode make sure that the probe is set outside the potential gradient area of earth electrode and auxiliary earth electrode (also see “The Influence of Potential Gradient areas on Earth Resistance Measurement”). Such a condition is normally reached by allowing a distance of > 20 m between the earth electrode and the earth spikes as well as of the earth spikes to each other.
