5.2 Pradinis įjungimas
Įdėjus bateriją, paspauskite ĮJUNGTA/IŠJUNGTA button to power on the device. The LCD display will illuminate, indicating the device is ready for use.
6. Naudojimo instrukcijos
6.1 Pagrindinis matavimas
To perform a grounding resistance test:
- Įsitikinkite, kad prietaisas yra įjungtas.
- Atidarykite klamp žandikaulius paspausdami gaiduką.
- Padėkite klamp around the grounding conductor or circuit to be measured. Ensure the jaws are fully closed around the conductor.
- The resistance value will be displayed on the LCD screen. The device features fully automatic shifting.
- The single measurement time is approximately 0.5 seconds.

6.2 Single Point Grounding System, Auxiliary Measurement
For single point grounding systems where direct clamp measurement of the lead wire is not feasible, auxiliary methods can be used. The two-point method is illustrated below:

Image 6.2: Diagram showing the two-point method for auxiliary grounding resistance measurement. It depicts a grounding rod (RA) connected to a single point, with a wire extending to a natural grounding point (e.g., water pipe, buried metal) for measurement.
Norėdami naudoti šį metodą:
- Identify a natural grounding point with a low resistance value near the grounding point to be measured. Examples include a water pipe, fire hydrant, or other deeply buried metal structure.
- Connect a wire from the point to be measured to this auxiliary grounding point.
- Clamp the ETCR2100A+ around the connecting wire to perform the measurement.
