CAUTION
 When starting test the unit performs a preliminary check of the resistance
values of current probe (Rc) and voltage probe (Rp) stopping the test if
these values are assumed to be too high and giving the messages “Rc:
>2.0k
” and “Rp: >2.0k”. Decrease the resistance value wetting the
ground close to the probes and/or connect more probes in parallel
 High noise currents and voltages in earth could affect the measurement
results. In this case the tester displays the ”NOISE” warning

key to save the result inside memory (see § 8.1)
CAUTION
To view stored ground resistivity results on PC they must be downloaded to
the meter unit first. To download the results select earth results in Synchronize
menu (see § 5.1.3). After the results are downloaded the stored data in
the station unit will be automatically deleted
