AEMC Model 3711 Clamp-Gebruikershandleiding voor de aardingsweerstandsmeter

Invoering

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 Kaken: 1.25" opening to accommodate ground rods and cables up to 1000kcmil.
• LCD-scherm: Digital readout for resistance and current measurements.
• Bedieningsknoppen: For power, data hold, and mode selection.
• Batterijcompartiment: Located at the rear for a 9V battery.

Installatie en batterij-installatie

1. Open het klepje van het batterijcompartiment aan de achterkant van het instrument.
2. Insert the supplied 9V Alkaline battery, observing correct polarity.
3. Sluit het batterijklepje goed.
4. Press the "ON" button to power on the device. The display should illuminate.

Gebruiksaanwijzing

Ground Resistance Measurement

1. Power on the AEMC 3711.
2. Open de clamp klembekken door de ontgrendelingshendel in te drukken.
3. Plaats de clamp 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.

Stroommeting

1. Power on the AEMC 3711.
2. Open de clamp kaken.
3. Plaats de clamp 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) of 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).

Onderhoud en kalibratie

Schoonmaak

Reinig het instrument met een zachte, damp doek. Gebruik geen schurende reinigingsmiddelen of oplosmiddelen.

Batterij vervangen

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

Kalibratiecontrole

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.

Opslag

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.

Probleemoplossing

• No Display/Instrument Not Powering On: Controleer de batterijinstallatie en zorg ervoor dat de batterij voldoende is opgeladen. Vervang de batterij indien nodig.
• Onstabiele metingen: Zorg ervoor dat de clamp jaws are fully closed around the conductor. Verify there is no excessive electrical noise in the environment.
• "OL" of Overbelastingsindicatie: 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.
• Onjuiste metingen: Perform a calibration check using the 25Ω loop. If the issue persists, contact technical support.
