4. Setup

4.1 Battery Installation

The thermometer requires 2 x 1.5V AAA batteries (not included). To install:

1. Locate the battery compartment on the handle.
2. Open the compartment cover.
3. Insert two AAA batteries, ensuring correct polarity (+/-).
4. Close the battery compartment cover securely.

4.2 Initial Power On

Once batteries are installed, pull the trigger to power on the device. The display will light up, and the thermometer will be ready for use.

5. Operating Instructions

5.1 Basic Measurement

1. Point the thermometer at the target object.
2. Pull and hold the trigger. The laser pointer will activate (if enabled) to help aim.
3. The temperature reading will appear on the LCD display.
4. Release the trigger to hold the reading on the display. The device will automatically power off after 30 seconds of inactivity.

5.2 Distance-to-Spot Ratio (D:S)

The D:S ratio is crucial for accurate measurements. It defines the ratio of the distance from the thermometer to the target (D) to the diameter of the measurement spot (S). As the distance increases, the measurement spot size also increases. Ensure the target object completely fills the measurement spot for the most accurate readings.

• H2 Model: D:S = 12:1
• H3 Model: D:S = 50:1 (allows for more accurate measurements from farther distances)

5.3 Emissivity Adjustment

Emissivity (ε) is a measure of an object's ability to emit infrared energy. Different materials have different emissivity values. The default emissivity is 0.95, which is suitable for most organic materials and painted surfaces. For more accurate readings on other materials, adjust the emissivity:

1. Press the EMS button.
2. Use the Up/Down arrows to adjust the emissivity value.
3. Press EMS again to confirm and exit.

Refer to the table below for common emissivity values:

5.4 Unit Conversion (°C/°F)

Press the °C/°F button to toggle between Celsius and Fahrenheit temperature units.

5.5 Advanced Modes (MODE button)

Press the MODE button to cycle through various measurement modes:

• MAX: Displays the maximum temperature recorded during a continuous scan.
• MIN: Displays the minimum temperature recorded during a continuous scan.
• DIF: Shows the difference between the maximum and minimum measured values.
• AVG: Displays the average temperature of multiple measurements.
• HAL (High Alarm): Sets a high-temperature alarm threshold. If the measured temperature exceeds this, an alarm will sound (H3 model: up to 1400°C / 2552°F).
• LAL (Low Alarm): Sets a low-temperature alarm threshold. If the measured temperature falls below this, an alarm will sound (H3 model: down to -50°C / -58°F).
• STO (Storage): Accesses stored measurement records.

5.6 Laser ON/OFF

The laser pointer can be toggled on or off for targeting assistance. Refer to the display panel diagram for the laser indicator.

5.7 Automatic Power Off

The thermometer will automatically power off after approximately 30 seconds of inactivity to conserve battery life.

6. Maintenance

• Cleaning the Lens: Use a soft, clean cloth or cotton swab with a small amount of isopropyl alcohol to gently clean the lens. Do not use abrasive cleaners or solvents.
• Cleaning the Casing: Wipe the device casing with a damp cloth. Do not immerse the device in water.
• Battery Replacement: Replace batteries when the low battery indicator appears on the display.
• Storage: Store the thermometer in a dry, cool place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries.

7. Troubleshooting

• No Power: Check if batteries are installed correctly and have sufficient charge. Replace batteries if necessary.
• Inaccurate Readings:
  • Ensure the D:S ratio is appropriate for your measurement distance and target size.
  • Verify the emissivity setting matches the material being measured.
  • When measuring liquids, ensure no steam or vapor interferes with the sensor.
  • Avoid measuring highly reflective surfaces without adjusting emissivity.
• Display Errors: If the display shows unusual symbols or no reading, try removing and reinserting the batteries. If the issue persists, contact customer support.
• Laser Not Working: Check if the laser is enabled. If it still doesn't work, the laser module might be faulty.

9. User Tips

• For the most accurate temperature readings, ensure the target object is larger than the measurement spot size determined by the D:S ratio.
• When measuring liquids, especially hot ones, angle the thermometer to avoid steam or vapor interfering with the sensor, which can lead to inaccurate results. A 45-60 degree angle is often recommended.
• Remember that infrared thermometers measure surface temperature. They cannot measure the internal temperature of an object.
• Always check and adjust the emissivity setting for different materials to ensure measurement accuracy. The default 0.95 is a good starting point for many common surfaces.
• The thermometer is suitable for a wide range of applications including automotive maintenance, industrial heat treatment, food preparation, and cold storage monitoring.
