9. A soil resistivity value can be derived from the resistance reading and the stake geometry.
Note:
 The instrument will display the warning triangle and an excessive noise voltage indicator if the ground
noise voltage is above 40 V pk-pk (14 Vrms).
 The instrument will display the warning triangle and a voltage over-range condition if the ground
noise voltage is above 100 V – no resistance reading is possible under this condition.
