5. Kurulum
5.1. Pil Kurulumu
- Ölçüm cihazının arkasındaki pil bölmesi kapağını bulun.
- Bölmeyi açmak için kapağı aşağı doğru kaydırın.
- Insert three (3) AA batteries, ensuring correct polarity as indicated inside the compartment.
- Pil bölmesi kapağını yerine oturana kadar yukarı doğru kaydırarak yerine takın.
5.2. İlk Güç Açma
Press the power button to turn on the meter. The LCD will illuminate, and the device will perform a brief self-test before displaying the ready-to-measure screen.
6. Kullanım Talimatları
6.1. Ölçüm Alma
To measure moisture content:
- Sayacın açık olduğundan emin olun.
- Place the pinless sensor ball flat against the surface of the material you wish to measure. Ensure full contact for accurate readings.
- The moisture reading will be displayed on the LCD. The meter will automatically adjust for different material densities within its measurement range.
- Observe the moisture icons (low, medium, high) and listen for the audible alert tone, which will increase in frequency with higher moisture levels.
6.2. Using the Data Hold Function
Press the "HOLD" button (if available, or refer to specific button on device) to freeze the current reading on the display. Press it again to release the hold and resume live measurements.
6.3. Setting Alarm Levels
