AEMC Model 3711 Clamp-Boky Torolalana ho an'ny Mpampiasa ny Mpandrefy Fanoherana eny An-tany

Sava lalana

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.

Ground Resistance Measurement

1. Power on the AEMC 3711.
2. Sokafy ny clamp jaws by pressing the release lever.
3. Apetraho ny 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.

Fandrefesana ankehitriny

1. Power on the AEMC 3711.
2. Sokafy ny clamp valanorano.
3. Apetraho ny 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) na 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).

Fikojakojana sy calibration

FANADIOVANA

Manadio ny fitaovana amin'ny malefaka, damp lamba. Aza mampiasa mpanadio abrasive na solvents.

Fanoloana bateria

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

Fanamarinana calibration

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.

fitahirizana

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.

Fanamboarana

• No Display/Instrument Not Powering On: Hamarino tsara ny fametrahana ny bateria ary ataovy izay hahazoana antoka fa ampy tsara ny bateria. Soloy raha ilaina.
• Famakiana tsy milamina: Ataovy azo antoka ny clamp jaws are fully closed around the conductor. Verify there is no excessive electrical noise in the environment.
• Famantarana ny "OL" na ny "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.
• Famakiana tsy marina: Perform a calibration check using the 25Ω loop. If the issue persists, contact technical support.
