Abnormalities Indications On The Display; Excessively High Spurious Voltages; Excessively High Earth Resistance - TENTECH EM4058 Manual De Uso

9. Abnormalities indications on the display

If the EM-4058 identifies any abnormality causing the measurements to
be excessively inaccurate or not possible at all, a warning message will
be shown on the display, allowing the operator to identify and correct the
problem.

9.1. Excessively high spurious voltages

If parasitic currents present in the soil are > 7 V and are seriously
affecting the equipment precision, the display will show the following
message:

9.2. Excessively high earth resistance

If the system's resistance is exceptionally high (above 20.00 kΩ), and
therefore beyond the equipment range, the following message will appear
(upper line):
