Note
The ratio that is preset from factory is correct for the EI162X sensing clamp
Press "START TEST" button.
Now a fully automated test sequence of all relevant parameters like auxiliary earth electrode, probe- and earth electrode resistance, is implemented and fin- ished with the display of the result RE.
1.Read out measured value RE
2.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 of earth electrode and auxiliary earth electrode (see also 12.5). Such a condition is normally reached by allowing a distance of >20 m between the earth electrode and the earth spikes as well as to the earth spikes to each other. An accuracy test of the re- sults is made by another measurement following repositioning of the auxiliary earth electrode or probe. If the value stays the same, the distance is sufficient. If the measured value changes, probe or auxiliary earth electrode must be repo- sitioned until the measured value RE stays constant.
Spikes wires should not run too close.
3-pole Measurement with Longer Earth Electrode Connect- ing Leads
1.Use one of the accessory cable drums as earth electrode connecting lead.
2.Spool off cable completely and compensate line resistance as de- scribed in “Compensation of Earth Electrode Connecting Lead”.
Time Average Measurement
If there is a warning "measured value unstable" (see “Description of Displays”, Procedure of Measurements) after a test sequence, most likely it is caused by strong interference signals (e.g. unsteady noise voltage). Nevertheless, to get
