5. Configuració

5.1 Instal·lació de la bateria

The ETCR2100A+ requires four (4) 1.5V AA batteries (not included).

1. Locate the battery compartment cover on the back of the instrument.
2. Use a suitable tool (if necessary) to open the battery compartment.
3. Insert four 1.5V AA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
4. Tanqueu bé la tapa del compartiment de la bateria.

5.2 Encès inicial

Després de la instal·lació de la bateria, premeu el botó ON/OFF button to power on the device. The LCD display will illuminate, indicating the device is ready for use.

6. Instruccions de funcionament

6.1 Mesura bàsica

To perform a grounding resistance test:

1. Assegureu-vos que l'instrument està encès.
2. Obriu el clamp mandíbules prement el gallet.
3. Col·loqueu el clamp around the grounding conductor or circuit to be measured. Ensure the jaws are fully closed around the conductor.
4. The resistance value will be displayed on the LCD screen. The device features fully automatic shifting.
5. 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.

Per utilitzar aquest mètode:

• 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.

6.3 Emmagatzematge i recuperació de dades

The instrument can store up to 99 sets of measurement data.

• To store data: After a measurement, press the MEM button to save the current reading.
• To retrieve data: Press the MEM button repeatedly to cycle through stored data.

6.4 Funció d'alarma

The ETCR2100A+ features an audible and visual alarm for out-of-range measurements.

• To activate/deactivate the alarm: Press the AL botó.
• To set alarm thresholds: Refer to the device's on-screen menu or specific instructions for setting resistance (1-199 Ω) and current (1-499mA) alarm limits.
