AEMC Model 3711 Clamp-Bhuku reMushandisi weKuedza Kurwisa Pasi

Nhanganyaya

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.

Product Overview

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 Shaya: 1.25" opening to accommodate ground rods and cables up to 1000kcmil.
• Chiratidziro cheLCD: Digital readout for resistance and current measurements.
• Mabhatani ekudzora: For power, data hold, and mode selection.
• Battery Compartment: Located at the rear for a 9V battery.

Setup uye Kuisa Battery

1. Open the battery compartment cover on the rear of the instrument.
2. Insert the supplied 9V Alkaline battery, observing correct polarity.
3. Vhara chivharo chebhatiri zvakachengeteka.
4. Press the "ON" button to power on the device. The display should illuminate.

Operating Instruction

Ground Resistance Measurement

1. Power on the AEMC 3711.
2. Vhura clamp jaws by pressing the release lever.
3. Isa 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.

Chiyero Chazvino

1. Power on the AEMC 3711.
2. Vhura clamp shaya.
3. Isa 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) kana milliAmpere (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).

Maintenance uye Calibration

Kuchenesa

Geza chiridzwa nechinyoro, damp jira. Usashandise abrasive cleaners kana solvents.

Kutsiviwa kwebhatiri

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

Calibration Check

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.

Storage

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.

Kugadzirisa matambudziko

• Hapana Chiratidziro/Chishandiso Chisingabatidzwe: Tarisa kuiswa kwebhatiri uye iva nechokwadi chekuti bhatiri rachaja zvakakwana. Ritsive kana zvichidikanwa.
• Kuverenga Kusina Kugadzikana: Iva nechokwadi chekuti clamp jaws are fully closed around the conductor. Verify there is no excessive electrical noise in the environment.
• "OL" kana kuti Chiratidzo chekuwedzera mutoro: 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.
• Kuverenga Kusina Kurongeka: Perform a calibration check using the 25Ω loop. If the issue persists, contact technical support.
