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 Rahang: 1.25" opening to accommodate ground rods and cables up to 1000kcmil.
- Layar LCD: Digital readout for resistance and current measurements.
- Tombol kontrol: For power, data hold, and mode selection.
- Kompartemen batré: Located at the rear for a 9V battery.
Setelan sareng Pamasangan Batré
- Open the battery compartment cover on the rear of the instrument.
- Insert the supplied 9V Alkaline battery, observing correct polarity.
- Tutup panutup kompartemen batré aman.
- Press the "ON" button to power on the device. The display should illuminate.
Parentah Operasi
Ground Resistance Measurement
- Power on the AEMC 3711.
- Buka clamp jaws by pressing the release lever.
- Nempatkeun clamp around the ground conductor or rod to be tested, ensuring the jaws are fully closed.
- The instrument will automatically measure and display the ground resistance in Ohms (Ω).
- For stable readings, allow approximately one second for the measurement to settle.
- To hold the current reading on the display, press the "HOLD" button. Press again to release.
Pangukuran ayeuna
- Power on the AEMC 3711.
- Buka clamp rahang.
- Nempatkeun clamp around the conductor carrying the current to be measured (leakage, neutral, or phase current). Ensure the jaws are fully closed.
- The instrument will automatically measure and display the current in Amperes (A) atanapi milliAmperes (mA).
- 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).

Ngagantian batré
When the low battery indicator appears on the display, replace the 9V battery as described in the "Setup and Battery Installation" section.
Cék Kalibrasi
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.
Panyimpenan
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.
Pamérésan masalah
- No Display/Instrument Not Powering On: Pariksa pamasangan batré sareng pastikeun batréna gaduh muatan anu cekap. Ganti upami diperyogikeun.
- Bacaan teu stabil: Pastikeun clamp jaws are fully closed around the conductor. Verify there is no excessive electrical noise in the environment.
- Indikasi "OL" atanapi Overload: 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.
- Bacaan teu akurat: Perform a calibration check using the 25Ω loop. If the issue persists, contact technical support.
