When the voltage drops to 5.2V, the battery symbol " " is displayed.
Please replace the battery. Low battery voltage affects measurement
accuracy.
ⅩI. Field Application
1. Multi-Point Grounding System
As for the multi-point grounding system (such as electricity
transmission tower grounding system, grounding cable
communications systems, certain buildings, etc.), They usually
pass the overhead ground wire (cable shielding layer) connected to
form a grounding system.See below. As the Meter is in the above
measurement, its equivalent electric circuit is shown in the figure
below:
Where: R
1
is the target grounding resistance.
R
0
is the equivalent resistance of the other entire tower
grounding resistances paralleled.
Although strictly on the theoretical grounding, because of the
