AEMC Model 3711 Clamp- Instrukcja obsługi testera rezystancji uziemienia

Wstęp

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.

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 Szczęki: 1.25" opening to accommodate ground rods and cables up to 1000kcmil.
• Wyświetlacz LCD: Digital readout for resistance and current measurements.
• Przyciski sterujące: For power, data hold, and mode selection.
• Komora baterii: Located at the rear for a 9V battery.

Konfiguracja i instalacja baterii

1. Open the battery compartment cover on the rear of the instrument.
2. Insert the supplied 9V Alkaline battery, observing correct polarity.
3. Dokładnie zamknij pokrywę komory baterii.
4. Press the "ON" button to power on the device. The display should illuminate.

Instrukcja obsługi

Ground Resistance Measurement

1. Power on the AEMC 3711.
2. Otwórz klamp jaws by pressing the release lever.
3. Umieść klamp 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.

Pomiar prądu

1. Power on the AEMC 3711.
2. Otwórz klamp szczęki
3. Umieść klamp 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) lub miliAmpery (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).

Konserwacja i kalibracja

Czyszczenie

Wyczyść instrument miękką, damp ściereczka. Nie należy używać środków czyszczących o właściwościach ściernych ani rozpuszczalników.

Wymiana baterii

When the low battery indicator appears on the display, replace the 9V battery as described in the "Setup and Battery Installation" section.

Kontrola kalibracji

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.

Składowanie

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.

Rozwiązywanie problemów

• No Display/Instrument Not Powering On: Sprawdź instalację akumulatora i upewnij się, że jest on wystarczająco naładowany. W razie potrzeby wymień.
• Niestabilne odczyty: Upewnij się, że clamp jaws are fully closed around the conductor. Verify there is no excessive electrical noise in the environment.
• „OL” lub wskaźnik przeciążenia: 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.
• Niedokładne odczyty: Perform a calibration check using the 25Ω loop. If the issue persists, contact technical support.
