2. Kuasa Awal Hidup
After battery installation, press the trigger to power on the device. The LCD display will illuminate.
Arahan Operasi
1. Mengambil Pengukuran
- 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)
Tekan ke ° C / ° F button (usually located near the display) to switch between Celsius and Fahrenheit temperature units.
3. Pelarasan Emisiviti
Emissivity (EMS) is crucial for accurate infrared temperature measurement. The GM-900 allows adjustment from 0.10 to 1.00 (default is 0.95).
- Tekan ke SET button to enter emissivity adjustment mode.
- Use the Up/Down arrow buttons to increase or decrease the emissivity value.
- Tekan SET sekali lagi untuk mengesahkan dan keluar.
4. Penunjuk Laser
The laser pointer assists in targeting the measurement area. Press the laser button (often depicted with a laser icon) to toggle the laser on or off.
5. Lampu latar
Press the backlight button (often depicted with a light bulb icon) to toggle the LCD backlight on or off for better visibility in different lighting conditions.
6. Advanced Functions (MODE Button)
The MODE button cycles through various measurement functions:
- MAKS: Memaparkan suhu maksimum yang direkodkan semasa imbasan berterusan.
- MIN: Memaparkan suhu minimum yang direkodkan semasa imbasan berterusan.
- AVG: Memaparkan suhu purata yang direkodkan semasa imbasan berterusan.
- DIF: Displays the difference between the maximum and minimum temperatures recorded.
- HAL (Penggera Tinggi): Set a high temperature alarm. If the measured temperature exceeds this value, an alarm will sound.
- LAL (Penggera Rendah): Set a low temperature alarm. If the measured temperature falls below this value, an alarm will sound.
- STO (Storage): Access memory storage (up to 12 data points).
To set alarm values, select HAL or LAL mode, then use the Up/Down arrow buttons to adjust the threshold. Press SET untuk mengesahkan.
Penyelenggaraan
1. Membersihkan Lensa
The infrared lens is the most delicate part of the thermometer. Clean it carefully with a soft cloth or cotton swab and water, or medical alcohol. Do not use abrasive cleaners or solvents.
2. Membersihkan Casing
Clean the thermometer casing dengan iklanamp cloth and mild soap. Do not immerse the device in water.
3. Penyimpanan
Store the thermometer in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the battery to prevent leakage.
