Chauvin Arnoux CA 6462 Grounding Tester User Manual

1. Introducció

The Chauvin Arnoux CA 6462 is a robust and user-friendly grounding tester designed for on-site use. It provides precise, reliable, and rapid diagnosis for establishing new grounds or checking existing grounding systems. This device is essential for professionals requiring accurate earth and ground resistance measurements in various applications.

The CA 6462 features three primary measurement functions: earth resistance, ground resistance, and transition resistance. It offers a wide measurement range from 0.01 to 2000 Ohms across three automatic ranges, ensuring versatility for different testing scenarios. Its design includes a sealed IP53 housing with a snap lid for durability in challenging environments.

2. Instruccions de seguretat

Always adhere to the following safety guidelines to prevent injury and ensure proper operation of the CA 6462:

• Llegiu aquest manual detingudament abans de fer funcionar el dispositiu.
• Ensure the device is in good working condition before each use. Do not use if damaged.
• Always wear appropriate personal protective equipment (PPE) when conducting electrical measurements.
• No excedeixi el vol especificattage or current ratings of the device.
• Avoid making measurements in wet or damp conditions unless the device is specifically rated for such environments and proper precautions are taken.
• Disconnect all test leads from the circuit before opening the battery compartment or performing any maintenance.
• Only use accessories and replacement parts specified by Chauvin Arnoux.

4. Configuració

Before using the CA 6462, ensure it is properly set up and powered.

4.1. Alimentació del dispositiu

The CA 6462 is battery-powered. Ensure the batteries are correctly installed and sufficiently charged. The "CHARGE" indicator on the display will provide feedback on battery status. Refer to the maintenance section for battery replacement instructions.

4.2. Connexió dels cables de prova

Connect the test leads to the corresponding color-coded terminals on the device. The specific connection method will depend on the type of measurement being performed (e.g., 3-pole or 4-pole earth resistance). Refer to the operating instructions for detailed connection diagrams for each measurement type.

• H (Red): Current electrode connection.
• S (Blue): Potential electrode connection.
• ES (Yellow): Auxiliary potential electrode connection.
• E (Green): Earth electrode connection.

5. Instruccions de funcionament

The CA 6462 offers three main measurement functions. Follow these steps for accurate readings.

5.1. Earth Resistance Measurement (3-Pole Method)

1. Connect the test leads to the E, S, and H terminals.
2. Place the auxiliary electrodes (potential and current) at appropriate distances from the earth electrode under test, following standard measurement practices.
3. Ensure the short-circuit bridge is in place between E and ES terminals if using a 3-pole configuration with a 4-pole device.
4. Premeu el botó PROVA botó.
5. Observe the digital display for the resistance value. The AUTO-CHECK indicators will confirm measurement validity (e.g., no fault, high resistance, or high noise).

5.2. Earth Resistance Measurement (4-Pole Method)

1. Connect the test leads to the E, ES, S, and H terminals.
2. Place the four electrodes (earth, auxiliary potential, potential, and current) in a straight line at equal distances.
3. Ensure the short-circuit bridge is removed from between E and ES terminals.
4. Premeu el botó PROVA botó.
5. Llegiu el valor de la resistència a la pantalla digital.

5.3. Interpreting AUTO-CHECK Indicators

• FALLA: Indicates an issue with the measurement circuit or connections. Check leads and electrode placement.
• HIGH RESISTANCE: Suggests that the resistance of the auxiliary electrodes is too high, potentially affecting accuracy. Improve electrode contact or reposition.
• HIGH NOISE: Indicates significant electrical interference. Try to reduce noise sources or perform the measurement at a different time/location.

The device operates at a measurement frequency of 128 Hz, which helps in mitigating interference from mains frequencies.

6. Manteniment

Proper maintenance ensures the longevity and accuracy of your CA 6462.

6.1. Neteja

Netegeu el dispositiu regularment amb un drap suau iamp drap. No utilitzeu productes de neteja abrasius ni dissolvents. Assegureu-vos que el dispositiu estigui sec abans de guardar-lo o utilitzar-lo el proper cop.

6.2. Substitució de la bateria

When the "CHARGE" indicator signals low battery, replace the batteries promptly. Refer to the battery compartment for the correct battery type and polarity. Always use high-quality batteries to ensure optimal performance and prevent leakage.

6.3. Emmagatzematge
