4. Asennus

4.1 Akun asennus

The BT-1800 requires one 9V battery (included). Follow these steps to install the battery:

1. Locate the battery door at the bottom of the handle.
2. Use the provided screwdriver to loosen the screw securing the battery door.
3. Open the battery door and connect the 9V battery to the terminal.
4. Place the battery into the compartment, ensuring correct polarity.
5. Sulje akun kansi ja kiristä ruuvi.

5. Käyttöohjeet

5.1 Lämpötilan perusmittaus

1. Suuntaa lämpömittari kohdepintaan.
2. Paina ja pidä painettuna Laukaista to begin measurement. The temperature reading will appear on the LCD screen.
3. Vapauta Laukaista to hold the reading. The "HOLD" icon will appear.
4. The device will automatically power off after approximately 30 seconds of inactivity to conserve battery.

5.3 Taustavalo ja taskulamppu

To improve visibility in low-light conditions:

• Paina Taustavalo/taskulamppupainike (labeled with a lightbulb icon) to turn the LCD backlight on or off.
• To activate the front flashlight, press and hold the Taustavalo/taskulamppupainike simultaneously with the Laukaista.

5.4 Yksikön vaihto (°C/°F)

To switch between Celsius (°C) and Fahrenheit (°F) temperature units, press the °C/DN or °F/UP -painiketta.

5.5 Measurement Modes (MAX/MIN/AVG/DIF/LAL/HAL)

Paina MODE-painike to cycle through different measurement modes:

• MAX: Näyttää nykyisen skannauksen aikana mitatun maksimilämpötilan.
• MIN: Näyttää nykyisen skannauksen aikana mitatun alimman lämpötilan.
• AVG: Näyttää nykyisen skannauksen aikana mitatun keskilämpötilan.
• DIF: Näyttää mitattujen maksimi- ja minimilämpötilojen välisen eron.
• LAL (Matalan lämpötilan hälytys): Allows setting a low temperature alarm. If the measured temperature falls below this value, an alarm will sound.
• HAL (korkea hälytys): Allows setting a high temperature alarm. If the measured temperature exceeds this value, an alarm will sound.

To set LAL or HAL values, long press the MODE-painike until "LAL" or "HAL" flashes. Use the °F/UP ja °C/DN buttons to adjust the desired temperature threshold.

5.6 Emissiivisyyden säätö

Emissivity (ε) is a measure of an object's ability to emit infrared energy. Different materials have different emissivity values. For accurate readings, adjust the emissivity setting (0.1 to 1.0) to match the target material.

To adjust emissivity, long press the MODE-painike until "ε" flashes. Use the °F/UP ja °C/DN buttons to change the value. Refer to a standard emissivity table for common materials if needed.

6. Huolto

• Puhdistus: Pyyhi laite puhtaaksi pehmeällä,amp kangas. Älä käytä hankaavia puhdistusaineita tai liuottimia.
• Linssien hoito: The infrared lens is a delicate part. Clean it gently with a soft cloth or cotton swab and rubbing alcohol, or a lens cleaning solution. Avoid touching the lens directly.
• Akun vaihto: Vaihda 9 V:n paristo, kun pariston heikon varauksen ilmaisin ilmestyy LCD-näyttöön.

7. Vianmääritys

If you encounter issues with your BT-1800 thermometer, consider the following common solutions:

• Ei näyttöä/laite ei käynnisty:
  • Check if the battery is installed correctly with the right polarity.
  • Vaihda 9 V:n paristo uuteen.
• Epätarkkoja lukemia:
  • Ensure the emissivity setting matches the target material.
  • Verify the distance-to-spot ratio is appropriate for your measurement.
  • Clean the infrared lens if it appears dirty.
  • Allow the thermometer to stabilize to ambient temperature if moved from a significantly different temperature environment.
• Laser ei toimi:
  • Paina Laser Pointer Button to ensure it is activated.
