AEMC Model 3711 Clamp-Benutzerhandbuch für den Erdungswiderstandsmesser

Einführung

The AEMC Model 3711 is a portable clamp-on ground resistance tester designed for measuring electrical ground rod and grid resistance in multi-grounded systems. This instrument offers a non-intrusive method for testing without the need for auxiliary rods or disconnecting the ground system. It also measures leakage, neutral, and phase currents, providing a comprehensive solution for electrical system analysis.

Image: The AEMC Model 3711 Clamp-On Ground Resistance Tester. This image displays the device with its red clamp jaws open, a black body, and a green digital display showing "9.8 Ω". Control buttons are visible below the display.

The AEMC Model 3711 features an ergonomic design for one-handed operation. Its robust polycarbonate construction ensures durability for outdoor use. Key components include:

• Clamp Kiefer: 1.25" opening to accommodate ground rods and cables up to 1000kcmil.
• LCD Anzeige: Digital readout for resistance and current measurements.
• Bedientasten: For power, data hold, and mode selection.
• Batteriefach: Located at the rear for a 9V battery.

Einrichtung und Batterieinstallation

1. Open the battery compartment cover on the rear of the instrument.
2. Insert the supplied 9V Alkaline battery, observing correct polarity.
3. Schließen Sie den Batteriefachdeckel fest.
4. Press the "ON" button to power on the device. The display should illuminate.

Bedienungsanleitung

Ground Resistance Measurement

1. Power on the AEMC 3711.
2. Öffne dieamp jaws by pressing the release lever.
3. Platzieren Sie dieamp around the ground conductor or rod to be tested, ensuring the jaws are fully closed.
4. The instrument will automatically measure and display the ground resistance in Ohms (Ω).
5. For stable readings, allow approximately one second for the measurement to settle.
6. To hold the current reading on the display, press the "HOLD" button. Press again to release.

Strommessung

1. Power on the AEMC 3711.
2. Öffne dieamp Kiefer.
3. Platzieren Sie dieamp around the conductor carrying the current to be measured (leakage, neutral, or phase current). Ensure the jaws are fully closed.
4. The instrument will automatically measure and display the current in Amperes (A) oder MilliAmperes (mA).
5. The current measurement function provides direct readings for leakage current flowing to ground or circulating in ground loops (down to 1mA) and neutral/phase currents (up to 30A RMS).

Wartung und Kalibrierung

Reinigung

Reinigen Sie das Instrument mit einem weichen,amp Tuch. Keine Scheuer- oder Lösungsmittel verwenden.

Batteriewechsel

Wenn die Anzeige für niedrigen Batteriestand erscheint, tauschen Sie die 9V-Batterie wie im Abschnitt „Einrichtung und Batterieeinbau“ beschrieben aus.

Kalibrierungsprüfung

Use the supplied 25Ω calibration check loop to verify the instrument's accuracy periodically. Clamp the tester around the loop; the reading should be approximately 25Ω. If the reading deviates significantly, contact AEMC customer support for service.

Lagerung

Store the instrument in its hard carrying case in a dry, cool environment when not in use. Remove the battery if storing for extended periods.

Fehlerbehebung

• No Display/Instrument Not Powering On: Prüfen Sie den Einbau der Batterie und stellen Sie sicher, dass die Batterie ausreichend geladen ist. Tauschen Sie sie gegebenenfalls aus.
• Instabile Messwerte: Stellen Sie sicher, dass die clamp jaws are fully closed around the conductor. Verify there is no excessive electrical noise in the environment.
• „OL“ oder Überlastungsanzeige: The measured value exceeds the instrument's range. Ensure the correct measurement function is selected or the circuit parameters are within the device's limits.
• Ungenaue Messwerte: Perform a calibration check using the 25Ω loop. If the issue persists, contact technical support.
