industrial and electrical equipment.
ETCR series of Pincers Earth Tester, in the measurement of a
grounding system with loop current, does not require breaking
down the grounding wire, and need no auxiliary electrode. It is safe,
fast and simple in use.
ETCR series of Pincers Earth Tester can measure out the
faults beyond the reach of the traditional methods, and can be
applied in the occasions not in the range of the traditional methods.
ETCR series of Pincers Earth Tester can measure the
integrated value of the grounding body resistance and the
grounding lead resistance.
ETCR series of Pincers Earth Tester is equipped with a long
jaw, as indicated in the figure below. A long jaw is particularly
suitable for the occasion of grounding with the flat steel.
In addition,
C+ Pincers Earth Tester is also able to measure the leakage
current and the neutral current in the grounding system.

- Incorrect battery polarity: Ensure batteries are installed correctly.
- Poor contact of battery contacts: Check and clean or replace the battery contacts.
- Wrong battery type: Use the correct battery type.
- A break in the battery harness: Perform a continuity test; replace the harness if no continuity.
- Displaced POWER button: Re-assemble the button.
- Poor contact of power plug: Re-plug or replace the plug.
