Operation Instruction
4.3. Measurement of the resistance by Tri-pole method
Potential Drop Method is used by the meter for the measurement of the earth resistance. Particular-
ly, RX, the earth resistance is figured out by first allowing I, the rated current, to flow between E, the
object measured (the earth rods) and C, the current pole, then measuring V, the potential difference
between E and P, the voltage pole.
(1) Connect the test leads to the meter as follows.
