3. ترتیب کول
3.1. د بیټرۍ نصب کول
- Locate the battery compartment cover, typically on the back or side of the device.
- 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.
- د بیټرۍ کمپارټ پوښ په خوندي ډول بدل کړئ.
3.2. بریښنا کول/بندول
- په وسیله د بریښنا کولو لپاره، فشار ورکړئ د بریښنا تڼۍ (
). The display will illuminate. - وسیله به د بیټرۍ ژوند ساتلو لپاره د 5 دقیقو غیر فعالیت وروسته په اتوماتيک ډول بریښنا بنده کړي.
- د لاسي بریښنا بندولو لپاره، فشار ورکړئ او ونیسئ د بریښنا تڼۍ.
4. عملیاتي لارښوونې
4.1. Selecting Measurement Modes
The Mastfuyi FY8861 offers two moisture measurement modes and an ambient temperature measurement mode. Use the د SEL ت buttonۍ 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 سور. 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):
فشار ورکړئ د SEL ت buttonۍ once to switch to Mode B. The indicator light will be شین. This mode is designed for measuring moisture in building materials such as concrete and drywall. The measurement range is 0% to 40%.
Image 4.2: Device display showing Mode B for building material moisture measurement with a green indicator light.
- د محیطي تودوخې اندازه کول:
فشار ورکړئ د SEL ت buttonۍ 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 د SEL ت buttonۍ یو ځل بیا.

4.2. اندازه کول
- د اندازه کولو پنونو څخه محافظتي خولۍ لرې کړئ.
- Select the appropriate measurement mode (Wood or Building Material) using the د SEL ت buttonۍ.
- 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 په سکرین کې ښودل کیږي.
- 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.
- د اندازه کولو په جریان کې، فشار ورکړئ د MAX / MIN ت buttonۍ to toggle between displaying the maximum, minimum, or current reading.
- This allows you to capture peak data without continuously monitoring the display.

5. ساتنه
5.1. پاکول
- After each use, wipe the measurement pins with a clean, dry cloth to remove any residue.
- Clean the device body with a soft, damp ټوکر د کثافاتو پاکوونکي یا محلول مه کاروئ.
- ډاډ ترلاسه کړئ چې وسیله د ذخیره کولو دمخه په بشپړه توګه وچه ده.
5.2. ذخیره کول
- Always replace the protective cap over the measurement pins when not in use to prevent damage and injury.
- وسیله په یخ او وچ ځای کې وساتئ، د مستقیم لمر وړانګو او سختې تودوخې څخه لرې.
- که چیرې د اوږدې مودې لپاره ذخیره کوئ، نو د لیکیدو مخنیوي لپاره بیټرۍ لرې کړئ.
6. ستونزه حل کول
6.1. No Reading or "Lo" Display
- لامل: If the material (e.g., wood board) is extremely dry, it acts as an insulator, preventing electrical conductivity between the two pins.
- حل لاره: 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.
۳. ناسم لوستل
- 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.
- د بیټرۍ کچه: A low battery can affect accuracy. Replace batteries if the battery indicator is low.
- د چاپیریال عوامل: Extreme humidity or temperature can sometimes influence readings. Allow the device to acclimate to the environment.
۶.۱. وسیله نه چالانېږي
- بیټرۍ چیک کړئ: Ensure batteries are correctly installed with proper polarity and are not depleted. Replace with fresh AAA batteries if necessary.
- د بیټرۍ کڅوړه: Confirm the battery compartment cover is securely closed.
