3. Gwybodaeth Diogelwch

Please read and understand all safety warnings before using this product. Failure to do so may result in injury or damage to the device.

• Diogelwch laser: This device uses a Class 2 laser product (optical power <0.5mW, Wavelength 630~670 um). PEIDIWCH SYLW AR BEAM. Avoid direct eye exposure to the laser.
• Defnydd Arfaethedig: The BT-1800 is specifically designed for measuring temperatures of inanimate objects. It is NOT ACCURATE FOR HUMAN OR ANIMAL TEMPERATURE MEASUREMENT and should not be used for medical purposes. Using it for biological temperature measurement may result in lower, inaccurate readings.
• Rhybudd Tymheredd Uchel: When measuring high temperatures, be aware of the surrounding environment and potential hazards. Maintain a safe distance from hot surfaces.
• Diogelwch Batri: Ensure correct battery polarity when installing. Do not mix old and new batteries. Remove batteries if the device will not be used for an extended period to prevent leakage.
• Storio: Storiwch y ddyfais mewn lle oer, sych, i ffwrdd o olau haul uniongyrchol a thymheredd eithafol.
• Glanhau: Clean the device with a soft, dry cloth. Do not use abrasive cleaners or immerse the device in water.

4. Gosod

4.1 Gosod Batri

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

1. Locate the battery compartment on the handle of the thermometer (refer to Figure 2).
2. Gently pull down the battery compartment cover.
3. Connect the 9V battery to the battery connector, ensuring correct polarity (+ to + and - to -).
4. Insert the battery into the compartment and close the cover securely.

4.2 Attaching the Carabiner (Optional)

The BT-1800 comes with a metal screw hole at the base of the handle, allowing it to be fixed on a tripod or to attach the included D-shape buckle (carabiner) for easy carrying on belt loops.

1. Locate the screw hole at the bottom of the handle.
2. Use the provided screwdriver to remove the small screw covering the hole.
3. Screw the carabiner into the threaded hole until secure.

5.2 Changing Temperature Units (°F/°C)

Gwasgwch y °F/UP button to switch between Fahrenheit (°F) and Celsius (°C) temperature units.

5.3 Mode Selection (MAX/MIN/AVG/DIF)

Gwasgwch y MODD botwm i gylchu trwy wahanol ddulliau mesur:

• MAX: Displays the maximum temperature measured during a scan.
• MIN: Displays the minimum temperature measured during a scan.
• AVG: Displays the average temperature measured during a scan.
• DIF: Displays the difference between the maximum and minimum temperatures measured.

5.4 Addasiad Allyrredd

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 to match the material being measured.

1. In measurement mode, long press the MODD button to enter emissivity adjustment.
2. Defnyddiwch y °F/UP a °C/DN buttons to adjust the emissivity value (0.1 to 1.0).
3. Gwasgwch MODD eto i gadarnhau ac ymadael.

Common Emissivity Values:

5.5 Laser Pointer and Flashlight Control

• Gwasgwch y Laser Pointer button (leftmost button below screen) to turn the laser pointers ON or OFF.
• Gwasgwch y Backlight / botwm Flashlight (second from left below screen) to turn the backlight ON or OFF.
• Gwasgwch y Backlight / botwm Flashlight a'r Sbardun simultaneously to turn the front flashlight ON or OFF.

5.6 Larwm Tymheredd Uchel / Isel

The device can be set to alert you when the measured temperature exceeds or falls below a set threshold.

1. Pwyswch yn hir y MODD button until "HAL" (High Alarm) or "LAL" (Low Alarm) appears.
2. Defnyddiwch y °F/UP a °C/DN buttons to set the desired high or low temperature threshold.
3. Gwasgwch MODD to switch between HAL and LAL settings.
