Operation
Basic Measurement
Diagram: User holding the thermometer and pointing it at a surface. The laser dot is visible on the surface.
- Press the trigger to activate the laser pointer and the device.
- Aim the laser at the center of the object you wish to measure. The distance-to-spot ratio of 12:1 means that at 12 inches away, the measurement spot is 1 inch in diameter.
- Release the trigger to hold the last reading on the display.
- The display shows the measured temperature, unit (°C or °F), and battery status.
Adjusting Emissivity

The emissivity setting allows for more accurate readings on different surface types. The default emissivity is 0.95, suitable for most common surfaces. To adjust:
- Press the 'EMISS' button.
- Use the UP/DOWN buttons to select the desired emissivity value (0.10 to 1.00).
- Press the trigger or wait a few seconds to confirm the setting.
Temperature Alarm

The device can be set to alert the user when the measured temperature exceeds a high or low threshold.
- Press the 'ALARM' button.
- Use the UP/DOWN buttons to set the High or Low alarm temperature.
- Press the trigger or wait to confirm. An indicator will appear on the display when an alarm condition is met. ?
Unit Selection (°C/°F)
Diagram: Display showing temperature in Celsius and Fahrenheit.
To switch between Celsius and Fahrenheit:
- Press and hold the 'MODE' button for approximately 3 seconds.
- The unit displayed will toggle between °C and °F.
Maintenance and Care
- Clean the lens gently with a soft, damp cloth. Do not use solvents.
- Wipe the device body with a dry cloth.
- Replace the 9V battery when the low battery indicator appears on the display. ?
- Store the device in a cool, dry place when not in use.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate Readings | Incorrect emissivity setting | Adjust emissivity to match the surface. |
| Dirty lens | Clean the lens. | |
| Measuring from too far away | Ensure the distance-to-spot ratio is appropriate. | |
| Device does not turn on | Low or dead battery | Replace the 9V battery. ? |
| Battery not installed correctly | Check battery installation. | |
| Laser not visible | Device is off or battery is low | Turn on device or replace battery. |
