If resistance on the S pole is too high or if there is a disconnection near
the pole, the display will show:
Either resistance diffusion on the S pole may be excessively high, or there
is a disconnection nearby. Check the installation to correct the problem.
In both cases, if the problem is being caused by excessive resistance,
watering the rods or inserting several interconnected rods may reduce the
resistance, allowing measurements to take place correctly.
9.4. Excessively high soil resistivity
If soil resistivity is excessively high (above 50 kΩm), and therefore
beyond the equipment range, the following message will appear (upper
line):
