5. Instruccions de funcionament

The ETCR3200C supports multiple measurement methods. Always select the appropriate method for your application and ensure correct wiring.

5.1 Grounding Resistance Measurement

The instrument offers several methods for grounding resistance measurement:

• Three-Wire/Four-Wire Method: This is the standard and most accurate method.
  1. Connect the test leads and grounding stakes according to the 3-wire or 4-wire diagram on the case lid.
  2. Rotate the function switch to the "Grounding Resistance" mode.
  3. Premeu el botó PROVA botó per iniciar la mesura.
  4. El resultat es mostrarà a la pantalla.
• Double Clamp Mètode: Used for measuring grounding resistance without disconnecting the ground system.
  1. Connect the two current clamps to the designated ports on the meter.
  2. Clamp one clamp around the grounding conductor to be tested and the other around an auxiliary grounding conductor.
  3. Select the "Double Clamp Method" on the rotary switch.
  4. Premeu PROVA.
  5. The grounding resistance will be displayed.
• Two-Wire Simple Test: For quick checks where high accuracy is not critical.
  1. Connect the test leads as per the 2-wire diagram.
  2. Select the "2-Wire Test" mode.
  3. Premeu PROVA.

5.2 Soil Resistivity Measurement (Quadrupole Method)

This method uses four grounding stakes (Winner method) to measure soil resistivity.

1. Drive the four grounding stakes into the ground at equal distances in a straight line.
2. Connect the test leads to the stakes and the meter's C1, P1, P2, C2 terminals according to the soil resistivity diagram.
3. Set the electrode spacing range on the meter (1m to 100m).
4. Rotate the function switch to "Soil Resistivity" mode.
5. Premeu PROVA.
6. The soil resistivity value (in Ωm) will be displayed.

5.3 Mesura de corrent altern

The ETCR3200C can also measure AC current up to 600.0A.

1. Rotate the function switch to "AC Current" mode.
2. Open the jaws of the current clamp i clamp it around the conductor carrying the AC current.
3. The AC current value will be displayed automatically.

5.4 Data Storage and Communication

• The meter can store up to 300 groups of measurement data.
• Utilitza el LLEGIR button to recall stored data.
• Connect the meter to a computer via the USB interface using the provided cable.
• Utilize the monitoring software (if provided by the manufacturer) to upload, save, and print data.

6. Manteniment

• Neteja: Wipe the instrument with a soft, damp tela. No utilitzeu netejadors abrasius ni dissolvents.
• Emmagatzematge: Store the meter and its accessories in the provided carrying bag in a cool, dry place, away from direct sunlight and extreme temperatures.

• Calibració: For continued accuracy, periodic calibration by qualified personnel is recommended.

7. Solució De Problemes

If you encounter issues with your ETCR3200C, consider the following:

• Sense energia: Check battery charge. Ensure the function switch is not in the "OFF" position.
• Lectures inexactes:
  • Verify test lead connections are secure and correct for the selected method.
  • Ensure grounding stakes are properly inserted into the ground.
  • Check for environmental interference or poor contact.
  • Consider battery level; low battery can affect accuracy.
• "OL" o Indicació de sobrecàrrega: The measured value exceeds the instrument's range. Check the circuit or select a different range if available.
• Problemes de visualització: If the display is blank or erratic, try restarting the device. If the problem persists, contact support.

For persistent issues not resolved by these steps, contact customer support.
