Operating Instructions

Taking a Temperature Reading

1. Hold the device by the handle and point the infrared sensor (A) towards the surface you wish to measure.
2. Pull and hold the trigger (F). The laser pointer (B) will activate, indicating the target area.
3. The temperature reading will appear instantly on the LCD display (C). Continue holding the trigger for continuous measurement.
4. Release the trigger to hold the last measured temperature on the display. The device will automatically shut off after a period of inactivity to conserve battery life.

Changing Temperature Units (°C/°F)

To switch between Celsius (°C) and Fahrenheit (°F):

• With the device powered on (either by pulling the trigger or if it's in hold mode), press the Unit Conversion Button (E).
• The display will switch between °C and °F.

Optimal Measurement Distance

For best accuracy, ensure the target area is larger than the spot size of the measurement. The optimal distance-to-spot ratio (D:S) for this device is typically provided in the specifications. For general use, hold the device close enough to cover the desired measurement area without touching the surface.

Maintenance

Proper maintenance ensures the longevity and accuracy of your temperature reader.

• Cleaning: Use a soft, damp cloth to clean the device casing. Do not use abrasive cleaners or solvents. For the lens, use a soft cloth or cotton swab with a small amount of rubbing alcohol.
• Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for an extended period, remove the battery to prevent leakage.
• Battery Replacement: Replace the battery when the low battery indicator appears on the display.
