Betjeningsvejledning
1. At foretage en måling
- 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)
Tryk på ° C / ° F button (usually located near the display) to switch between Celsius and Fahrenheit temperature units.
3. Justering af emissivitet
Emissivity (EMS) is crucial for accurate infrared temperature measurement. The GM-900 allows adjustment from 0.10 to 1.00 (default is 0.95).
- Tryk på SÆT button to enter emissivity adjustment mode.
- Use the Up/Down arrow buttons to increase or decrease the emissivity value.
- Trykke SÆT igen for at bekræfte og afslutte.
4. Laserpointer
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. Baggrundsbelysning
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)
De MODE button cycles through various measurement functions:
- MAKS: Viser den maksimale temperatur, der er registreret under en kontinuerlig scanning.
- MIN: Viser den minimumstemperatur, der er registreret under en kontinuerlig scanning.
- AVG: Viser den gennemsnitlige temperatur, der er registreret under en kontinuerlig scanning.
- DIF: Viser forskellen mellem de registrerede maksimum- og minimumtemperaturer.
- 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 SÆT for at bekræfte.
Opretholdelse
1. Rengøring af linsen
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. Rengøring af Casing
Clean the thermometer casing med annonceamp cloth and mild soap. Do not immerse the device in water.
3. Opbevaring
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.
