- Carefully remove the cover. Some models may require unscrewing a small screw or sliding a latch.
- Insert two AAA 1.5V batteries, ensuring correct polarity (+/-) as indicated inside the compartment. Note: Some users report difficulty inserting batteries due to spring tension; gentle but firm pressure may be required.
- بيٽري جي ڪمري واري ڍڪ کي محفوظ طور تي تبديل ڪريو.
3.2. پاور آن/آف
- ڊوائيس تي طاقت ڪرڻ لاء، دٻايو پاور بٽڻ (
). The display will illuminate. - بيٽري جي زندگي بچائڻ لاءِ ڊوائيس 5 منٽن جي غير فعال ٿيڻ کان پوءِ خود بخود بند ٿي ويندي.
- To manually power off, press and hold the پاور بٽڻ.

4.1. Selecting Measurement Modes
The Mastfuyi FY8861 offers two moisture measurement modes and an ambient temperature measurement mode. Use the SEL بٽڻ to cycle through these modes.
- Mode A (Wood Moisture Measurement):
When the device is powered on, it typically defaults to Mode A. The indicator light will be ڳاڙهو. This mode is suitable for measuring moisture in various types of wood, from hardwood to softwood. The measurement range is 0% to 40%.

- Mode B (Building Material Moisture Measurement):
کي دٻايو SEL بٽڻ once to switch to Mode B. The indicator light will be سائو. This mode is designed for measuring moisture in building materials such as concrete and drywall. The measurement range is 0% to 40%.

- Ambient Temperature Measurement:
کي دٻايو SEL بٽڻ again to switch to ambient temperature measurement. In this mode, the indicator light will be off. You can toggle between Celsius (°C) and Fahrenheit (°F) by pressing the SEL بٽڻ هڪ ڀيرو وڌيڪ.

4.2. ماپڻ
- ماپ جي پنن مان حفاظتي ڪيپ کي هٽايو.
- Select the appropriate measurement mode (Wood or Building Material) using the SEL بٽڻ.
- Firmly insert the two measurement pins into the material you wish to test. For best results, push the pins deep enough to ensure good contact with the material.
- Read the moisture content percentage اسڪرين تي ڏيکاريل آهي.
- After measurement, carefully withdraw the pins and replace the protective cap.
4.3. MAX/MIN Value Freeze Function
The MAX/MIN function is useful for recording the highest or lowest moisture reading during a measurement session, especially when testing materials with varying moisture levels at different depths.
- ماپ دوران، دٻايو وڌ MAX بٽڻ to toggle between displaying the maximum, minimum, or current reading.
- This allows you to capture peak data without continuously monitoring the display.

5. سار سنڀال
5.1. صفائي
- After each use, wipe the measurement pins with a clean, dry cloth to remove any residue.
- Clean the device body with a soft, damp ڪپڙو. استعمال نه ڪريو abrasive cleaners يا solvents.
- Ensure the device is completely dry before storage.
5.2. اسٽوريج
- Always replace the protective cap over the measurement pins when not in use to prevent damage and injury.
- ڊوائيس کي ٿڌي، سڪل جاءِ تي، سڌي سج جي روشني ۽ انتهائي گرمي پد کان پري رکو.
- جيڪڏهن گهڻي عرصي تائين ذخيرو ڪري رهيا آهيو، ته پوءِ ليڪيج کي روڪڻ لاءِ بيٽريون هٽايو.
6. مسئلا حل ڪرڻ
6.1. No Reading or "Lo" Display
- سبب: If the material (e.g., wood board) is extremely dry, it acts as an insulator, preventing electrical conductivity between the two pins.
- حل: Ensure the material is not excessively dry. For accurate readings, the pins must make good electrical contact. Push the pins deep into the material. If the material is genuinely very dry, a "Lo" reading or no reading is expected and indicates low moisture.
6.2. غلط پڙهڻيون
- Check Pin Contact: Ensure both pins are fully inserted and making firm contact with the material.
- Select Correct Mode: Verify that you are using the correct mode (Wood or Building Material) for the material being tested.
- بيٽري جي سطح: A low battery can affect accuracy. Replace batteries if the battery indicator is low.
- ماحولياتي عنصر: Extreme humidity or temperature can sometimes influence readings. Allow the device to acclimate to the environment.
6.3. ڊوائيس پاور آن نٿو ٿئي
- بيٽري چيڪ ڪريو: Ensure batteries are correctly installed with proper polarity and are not depleted. Replace with fresh AAA batteries if necessary.
- بيٽري جو خانو: Confirm the battery compartment cover is securely closed.
