سار سنڀال ۽ حساب ڪتاب

صفائي

اوزار کي نرم سان صاف ڪريو، ڊيamp ڪپڙو. استعمال نه ڪريو abrasive cleaners يا solvents.

بيٽري مٽائڻ

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

حساب ڪتاب جي چڪاس

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.

ذخيرو

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.

مشڪلاتون

• No Display/Instrument Not Powering On: بيٽري جي انسٽاليشن چيڪ ڪريو ۽ پڪ ڪريو ته بيٽري ڪافي چارج ٿيل آهي. جيڪڏهن ضروري هجي ته ان کي تبديل ڪريو.
• غير مستحڪم پڙهڻ: cl کي يقيني بڻايو وڃيamp jaws are fully closed around the conductor. Verify there is no excessive electrical noise in the environment.
• "OL" يا اوورلوڊ اشارو: 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.
• غلط پڙھڻ: Perform a calibration check using the 25Ω loop. If the issue persists, contact technical support.
