آپريٽنگ هدايتون
1. ماپ کڻڻ
- Point the thermometer at the target object. Ensure the target fills the measurement spot as much as possible. Refer to the Distance to Spot Ratio (D:S) in the Specifications section.
- Press and hold the trigger. The temperature reading will appear on the LCD display instantly.
- Release the trigger to hold the reading on the display (Data Hold Function). The "HOLD" icon will appear.
2. Unit Selection (°C/°F)
کي دٻايو ° سي / ° ايف button (usually located near the display) to switch between Celsius and Fahrenheit temperature units.
3. Emissivity Adjustment
Emissivity (EMS) is crucial for accurate infrared temperature measurement. The GM-900 allows adjustment from 0.10 to 1.00 (default is 0.95).
- کي دٻايو سيٽ button to enter emissivity adjustment mode.
- Use the Up/Down arrow buttons to increase or decrease the emissivity value.
- دٻايو سيٽ ٻيهر تصديق ڪرڻ ۽ نڪرڻ لاءِ.
