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 ژامې: 1.25" opening to accommodate ground rods and cables up to 1000kcmil.
• د LCD نندارې: Digital readout for resistance and current measurements.
• د کنټرول تڼۍ: For power, data hold, and mode selection.
• د بیټرۍ کڅوړه: Located at the rear for a 9V battery.

د بیټرۍ تنظیم او نصب کول

1. Open the battery compartment cover on the rear of the instrument.
2. Insert the supplied 9V Alkaline battery, observing correct polarity.
3. د بیټرۍ کمپارټ پوښ په خوندي ډول وتړئ.
4. Press the "ON" button to power on the device. The display should illuminate.

4. The instrument will automatically measure and display the current in Amperes (A) یا ملیAmperes (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).

ساتنه او حساب ورکول

پاکول

وسیله په نرمۍ سره پاکه کړئ، دamp ټوکر د کثافاتو پاکوونکي یا محلول مه کاروئ.

د بیټرۍ بدلول

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

کیلیبریشن چک

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.

ذخیره کول

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.

د ستونزو حل کول

• No Display/Instrument Not Powering On: د بیټرۍ نصب کول وګورئ او ډاډ ترلاسه کړئ چې بیټرۍ کافي چارج لري. که اړتیا وي نو بدل یې کړئ.
• بې ثباته لوستل: ډاډ ترلاسه کړئ چې clamp jaws are fully closed around the conductor. Verify there is no excessive electrical noise in the environment.
• "OL" یا د ډیر بار نښه: 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.
• ناسم لوستل: Perform a calibration check using the 25Ω loop. If the issue persists, contact technical support.
