Цэвэрлэгээ

Багажийг зөөлөн арчиж цэвэрлэх, damp даавуу. Зүлгүүрийн цэвэрлэгч, уусгагчийг бүү ашигла.

Зай солих

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

Тохируулгын шалгалт

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.

Хадгалах

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.

Алдааг олж засварлах

• No Display/Instrument Not Powering On: Батерейны суурилуулалтыг шалгаж, хангалттай цэнэгтэй эсэхийг шалгана уу. Шаардлагатай бол солино уу.
• Тогтворгүй уншилтууд: cl-ийг баталгаажуулна ууamp jaws are fully closed around the conductor. Verify there is no excessive electrical noise in the environment.
• "OL" буюу Хэт ачааллын заалт: 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.
• Буруу уншилтууд: Perform a calibration check using the 25Ω loop. If the issue persists, contact technical support.
