1. In any grounding occasions, it can carry out the
test normally by using double-measuring method: non-contacting
and accessing piles. No matter the amount of grounding
point is multiple or single.
2. Online measuring is available. It can test the electric
equipment under its working condition without cutting
from the grounding part.
3. The capacity of anti-interference is strong. Even
in the 500kV transformer substation, it can produce
the high-frequency current to filtrate the harmonic
interference, like 50Hz or 100Hz from the electric current,
then feedback the accurate results.
4. The soil resistivity can be displayed automatically
without trivial calculation.
5. The inner storage with large capacity can save 100
groups of measuring datas.
6. The collocating charger and secondary battery is
designed for electricity saving, it will be cut automatically
when exceeding schedule time.
7. Four-line measurement ensures the accuracy of testing
for the grounding resistance below 0.7Ω.
8. The alarming system warms if surpassing the limitation
or using the incorrect testing condition.
9. Self-testing is also available.
1. Non-accessory electrode measuring for grounding resistance
of communication and power system is available to do
the test on the concrete-covering ground.
2. The soil resistivity measuring under the earthing
grid construction is easy to calculate the depth of
the grid for builder.
3. The digital tester for traditional grounding resistance
has a full-scale application, which is replacing the
pumping traditional meter.
4. The resistance tester is connected in the looping
