5.5.1. When the test current is 0.01A, there may be poor contact between the "current line" wiring
and the "current pole" ground spike or too few ground piles, the ground pile should be increased to
reduce the loop resistance. The depth of the ground spike shall not be less than 0.5m. Current spike
resistance should be less than 200 Ω.
5.5.2. If the measured value of the instrument display very low (< 0.01 Ω) could be the voltage line
not connection well.
5.5.3. When instrument in testing, it is necessary to connect the resistance above 20 ohms at C1
output terminal to simulate the site current pile resistance, otherwise cause the measurement data
with large error.
6. Attentions
6.1. In order to make the test run smoothly, please check whether the contact point of the test wire
and the ground pile is well with the multimeter before the test, and measure whether the connection
wiring is breaking phenomena or not.
6.2. The instrument will automatically eliminate the wiring error in 4-pole measurement.
6.3. In case of any other faults of the instrument, please contact the after-sales service department
of our company directly. Please do not disassemble and repair the instrument without permission.
7. Internal Power Supply Testing Wiring Reference
7.1. Grounding Conduction Measurement(G.Cont)
C1/P1 connect with a grounding device, C2/P2(measurement grounding end) connect with another
grounding device.
Note:
(1) Don't entwine the test leads.
(2) Voltage lines should be kept as far away from current lines as possible
(3) Both sides of the grounding clamp should be pressed against the geodesic to prevent paint rust
from causing bad contact.
(4) To prevent current protection, select the current 1A gear. Select the "G.Cont" "VF" mode 1A
