This manual provides detailed instructions for the safe and effective operation of your BTMETER BT-1800 High Temperature Infrared Thermometer. Please read this manual thoroughly before use and retain it for future reference.
The BT-1800 is a non-contact infrared thermometer designed for measuring extremely high temperatures in industrial applications such as metal melting furnaces, forges, kilns, and ceramic firing. It features a wide temperature range, high distance-to-spot ratio, and adjustable emissivity for accurate measurements.
Sigurnosne informacije
- Laserska sigurnost: This device uses a Class 2 laser product (Wavelength 630-670 nm, Output <0.5mW). Do not stare directly into the laser beam. Avoid directing the laser beam at eyes or reflective surfaces.
- Namjena: This thermometer is designed for measuring the temperature of inanimate objects only. It is not accurate for measuring human or animal body temperature and should not be used for medical purposes.
- Rukovanje: Pažljivo rukujte uređajem. Izbjegavajte ispuštanje ili izlaganje jakim udarcima.
- Okruženje: Ne izlažite uređaj ekstremnim temperaturama, vlazi ili korozivnim okruženjima.
- čišćenje: Pogledajte odjeljak Održavanje za odgovarajuće upute za čišćenje.

- Dugme laserskog pokazivača: Toggles the laser pointer on/off.
- okidač: Aktivira mjerenje i laser.
- Backlit Screen/Flashlight Button: Toggles screen backlight and the integrated flashlight.
- °C/DN Button: Changes temperature unit to Celsius and navigates down in menus.
- °F/UP Button: Changes temperature unit to Fahrenheit and navigates up in menus.
- Vrata za baterije: Omogućava pristup za ugradnju baterije.

The device also features a metal screw hole for tripod mounting and a D-shape buckle for attachment to belt loops, enhancing portability and stability during use.

Setup
Instalacija baterije
The BT-1800 requires a 9V battery for operation. Follow these steps to install or replace the battery:
- Pronađite odjeljak za baterije na dršci termometra.
- Otvorite vrata za bateriju.
- Connect the 9V battery to the battery connector, ensuring correct polarity.
- Place the battery into the compartment and close the battery door securely.
Pričvršćivanje karabinera
For convenient carrying, you can attach the provided carabiner to the base of the thermometer:
- Locate the small screw at the bottom of the handle.
- Use a small screwdriver to remove this screw.
- Insert the carabiner's loop into the hole and secure it by re-inserting and tightening the screw.
Uputstvo za upotrebu
Basic Temperature Measurement
- Usmjerite termometar prema ciljanom objektu.
- Pritisnite i držite Trigger to begin measurement. The laser pointer will activate to indicate the measurement area.
- The temperature reading will be displayed on the LCD screen. Release the trigger to hold the reading.


Konverzija jedinica (°F/°C)
Za prebacivanje između Celzijusa (°C) i Fahrenheita (°F), pritisnite °C/DN or °F/UP button while the device is on.
Mode Selection and Emissivity Adjustment
Pritisnite MODE button to cycle through various functions:
- MAX: Prikazuje maksimalnu temperaturu zabilježenu tokom skeniranja.
- MIN: Prikazuje minimalnu temperaturu zabilježenu tokom skeniranja.
- PROSJEČAN: Prikazuje prosječnu temperaturu zabilježenu tokom skeniranja.
- DIF: Prikazuje razliku između maksimalne i minimalne temperature.
- LAL (Niski alarm): Set a low temperature alarm. The device will flash if the measured temperature falls below this value.
- HAL (Visoki alarm): Set a high temperature alarm. The device will flash if the measured temperature exceeds this value.
- Emissivity (E): Adjust the emissivity setting (0.1 to 1.0) to match the surface being measured for improved accuracy. Consult a reference table for common material emissivities.
To adjust values (e.g., alarm thresholds or emissivity), use the °F/UP i °C/DN buttons after selecting the desired mode with the MODE dugme.
Laser Pointer and Flashlight
- Pritisnite Laser Pointer Button to turn the laser on or off. The BT-1800 features dual laser pointers for precise targeting.
- Pritisnite Backlit Screen/Flashlight Button to activate the screen backlight or the integrated flashlight for use in dark environments.

Odnos udaljenosti i tačke (D:S)
The BT-1800 has a Distance to Spot (D:S) ratio of 50:1. This means that at a distance of 50 units from the target, the measurement spot diameter will be 1 unit. A higher D:S ratio allows for accurate temperature measurement from a greater distance, which is crucial for high-temperature applications.

Automatsko isključivanje
The device features an automatic power-off function to conserve battery life. It will power off after a period of inactivity.
Održavanje
- čišćenje: Da biste očistili uređaj, obrišite ga mekom krpom, damp cloth. Do not use abrasive cleaners or solvents. Ensure the lens is clean for accurate readings.
- Zamjena baterije: Replace the 9V battery when the low power indicator appears on the display. Refer to the "Battery Installation" section for instructions.
- Skladištenje: Čuvajte termometar na hladnom i suvom mestu kada se ne koristi.
