1. The manufacturer of flexible graphite grounding strips reminds you that after backfilling and compacting the resistance reducing agent, you can test the resistance value. As time goes by, the resistance value will continue to decrease after the soil solidifies.
2. It is best to use a calibrated "shake handle" measuring instrument. Button battery type measuring instruments can also be used.
3. The measurement lead should be drawn from the east, south, and northwest directions (if not limited by terrain or features), measured four times, and then the arithmetic mean is taken,
4. Measurements should not be taken parallel to the horizontal grounding body, but should be taken perpendicular to it for measurement and grounding electrodes
5. If there are any abnormal phenomena (especially large or small) in the measurement of resistance, in addition to other tests (such as whether the meter is intact and whether the connection points are in good contact), it is necessary to check whether there are any metal objects near the measurement path.
6. Flexible graphite grounding strip manufacturers remind you that for extremely poor soil conditions (such as soil full of stones) or extremely narrow construction sites where the grounding body cannot be fully grounded, as well as when the measurement path resistance value is extremely high, the requirement for qualified grounding resistance should be reduced. If necessary, it is also possible to consider drilling holes and injecting resistance reducing agents at the measurement auxiliary pole to better reflect the true value of the measurement results.
