2) [Power module error, please contact the manufacturer], if the test continues, please
contact the manufacturer.
3) When the test current is 0.0A, the connection of the [current line] may be in poor
contact with the [current pole] ground pile or there are too few ground piles. It is
necessary to add ground piles to reduce loop resistance. The pile depth is not less than
0.5m. The resistance of the current pile should be less than 80Ω.
4) If the measured value displayed by the instrument is extremely low (<0.01Ω), it may be
that the voltage line is not connected.
5) When the instrument is tested, a resistor of more than 20 ohms can be connected in
series to the C1 output terminal to simulate the field current pile resistance.
6) To make the test go on smoothly, please use a multimeter to check whether the
contact point between the test lead and the ground pile is intact, and measure whether
the laid line is open.
7) The instrument will automatically eliminate wiring errors during the four-pole
measurement.
8) If there are other malfunctions in the instrument, please contact the after-sales service
department of our company directly, and do not disassemble the machine privately.
4. The measuring line is configured by the user according to the size of the ground
network.
