Instruccions de funcionament
1. Prendre una mesura
- 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)
Premeu el botó ° C / ° F 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).
- Premeu el botó SET button to enter emissivity adjustment mode.
- Use the Up/Down arrow buttons to increase or decrease the emissivity value.
- Premeu SET de nou per confirmar i sortir.
4. Punter làser
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. Llum de fons
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)
El MODE button cycles through various measurement functions:
- MÀXIM: Displays the maximum temperature recorded during a continuous scan.
- MIN: Displays the minimum temperature recorded during a continuous scan.
- AVG: Displays the average temperature recorded during a continuous scan.
- DIF: Mostra la diferència entre les temperatures màximes i mínimes registrades.
- HAL (High Alarm): Set a high temperature alarm. If the measured temperature exceeds this value, an alarm will sound.
- LAL (Low Alarm): 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 per confirmar.
Manteniment
1. Neteja de la lent
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. Neteja de la Casing
Netegeu el termòmetre casing amb anunciamp cloth and mild soap. Do not immerse the device in water.
3. Emmagatzematge
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.
