5. Setup

Battery Installation

The ANENG TH201 requires two AAA batteries (not included) for operation.

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

6. Operating Instructions

Basic Temperature Measurement

1. Point the thermometer at the object you wish to measure.
2. Pull and hold the measuring switch (trigger) to activate the device and begin scanning. The laser will indicate the measurement area.
3. The temperature reading will be displayed on the LCD screen.
4. Release the trigger to hold the last measured temperature on the screen.

Unit Switching (°C/°F)

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

Screen Backlight

Press the backlight button (light bulb icon) to turn the screen backlight on or off for improved visibility in dark environments.

Infrared Laser

Press the laser switch button (triangle icon) to turn the infrared laser on or off. The laser helps in accurately targeting the measurement spot.

Object Distance Ratio (D:S = 12:1)

The device has an object distance ratio of 12:1. This means that for every 12 units of distance (D) from the object, the measurement spot diameter (S) is 1 unit. As the distance to the measured object increases, the measurement area will also increase proportionally. Ensure you are at an appropriate distance for the desired measurement area.

Measurement Tips for Liquids (Water/Oil)

When measuring the temperature of boiling liquids, do not let the smoke and water vapor come into direct contact with the temperature sensing area. The recommended measurement angle is between 45° and 60° to avoid inaccurate readings caused by steam.

7. Application Scenarios

The ANENG TH201 is versatile and can be used in various settings:

• Air Conditioning: Measure air conditioner trend temperature.
• Electrical Systems: Check distribution box temperature.
• Cooking: Measure food temperature (e.g., frying, baking).
• Heating: Monitor boiler temperature.
• Automotive: Check car engine temperature.
• Refrigeration: Measure refrigerator/freezer temperatures.

9. Maintenance

• Cleaning: Use a soft, damp cloth to clean the device. Do not use abrasive cleaners or solvents.
• Storage: Store the thermometer in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery Replacement: Replace batteries when the low battery indicator appears on the screen to ensure accurate readings and proper device function.

10. Troubleshooting

• No Display/Device Not Turning On: Check if batteries are installed correctly and have sufficient charge. Replace with new AAA batteries if necessary.
• Inaccurate Readings: Ensure the measurement angle for liquids is correct (45°-60°). Verify the object distance ratio is appropriate for your target. Clean the sensor if it appears dirty.
• Low Temperature Alarm: If the device measures a very low temperature and issues an alarm, this indicates the measured temperature is below a certain threshold. This is a feature, not a malfunction.

11. User Tips

• Emissivity: The ANENG TH201 has a fixed emissivity of 0.95. This value is suitable for most organic materials, painted surfaces, and many non-metals. For highly reflective surfaces, readings might be less accurate.
• Quick Measurements: The 0.5-second response time allows for rapid temperature checks, making it efficient for scanning multiple points or monitoring changing temperatures.

12. Warranty and Support
