ANENG TH201 High Precision Infrared Thermometer User Manual

1. Introduction

The ANENG TH201 is a handheld, non-contact infrared thermometer designed for rapid and accurate temperature measurement. It utilizes infrared sensors to provide quick readings without direct contact, making it suitable for measuring hot, hazardous, or hard-to-reach objects. This device is applicable for various uses including industrial, household, and bakery environments. Key features include single-point laser positioning, a backlit LCD screen for clear visibility, and the ability to switch between Celsius and Fahrenheit units.

The thermometer measures temperatures across a wide range from -50°C to 400°C (-58°F to 752°F) with a fast response time of 0.5 seconds.

2. Safety Information

Warning & Cautions:

To avoid potential harm or damage to people, please observe the following:

• Before using this unit, carefully check the plastic housing for any damage. Do not use if damaged.
• Do not point the laser directly at eyes or indirectly off reflective surfaces.
• Do not use this unit in environments with explosive gas, steam, or dust.

Caution:

To avoid damage to the unit or the target, protect it from the following situations:

• Electromagnetic fields (EMF) from arc welders or induction heaters.

3. Package Contents

Upon opening the package, please ensure all items are present and in good condition:

• ANENG TH201 Infrared Thermometer (1 unit)
• Instruction Manual (1 copy)

4. Setup

4.1 Battery Installation

The ANENG TH201 thermometer requires two AAA batteries for operation. To install the batteries:

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.

5. Operating Instructions

5.1 Basic Temperature Measurement

To measure temperature:

1. Point the thermometer at the target object.
2. Pull and hold the trigger. The laser pointer will activate (if enabled) to help aim, and the temperature reading will appear on the LCD screen.
3. Release the trigger to hold the last measured temperature on the display.

5.2 Unit Switching (°C/°F)

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

• Press the '°C/°F' button located below the display. The unit on the screen will change accordingly.

5.3 Backlight Control

To turn the screen backlight on or off:

• Press the backlight button (represented by a light bulb icon) located below the display. This allows for clear visibility in dark environments.

5.4 Infrared Laser Setting

To enable or disable the infrared laser pointer:

• Press the laser switch key (represented by a triangle icon) located below the display. The laser helps in precise targeting of the measurement area.

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

The ANENG TH201 has an object distance ratio of 12:1. This means that as the distance (D) between the thermometer and the measured object increases, the diameter (S) of the measurement area will also increase proportionally. For accurate readings, ensure the target area is larger than the measurement spot size at the given distance.

Figure 5.4: Diagram illustrating the 12:1 object distance ratio (D:S).

5.6 Water/Oil Temperature Measurement Method

When measuring the temperature of boiling liquids, it is crucial to prevent smoke and water vapor from coming into contact with the thermometer's temperature sensing area. The recommended measurement angle is approximately 45° to 60° to avoid incorrect readings caused by steam interference.

5.7 Application Scenarios

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

• Air Conditioner Trend Temperature Measurement: Monitor the temperature of air conditioning units.
• Distribution Box Temperature Measurement: Check temperatures within electrical distribution boxes.
• Photography Lamp Temperature: Measure the heat generated by photography lights.
• Food Temperature Measurement: Suitable for checking food temperatures (e.g., cooking surfaces).
• Boiler Temperature Measurement: Monitor boiler temperatures.
• Refrigerator Refrigeration Temperature: Measure temperatures inside refrigerators or freezers.
• Car Engine Temperature: Check the temperature of car engine components.

7. Maintenance

7.1 Cleaning

To ensure accurate readings and prolong the life of your thermometer:

• Wipe the device with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Keep the infrared lens clean and free from dust or debris. Use a soft brush or compressed air to gently clean the lens if necessary.

7.2 Storage

When not in use, store the thermometer in a dry, cool place, away from direct sunlight and extreme temperatures.

8. Troubleshooting

8.1 Low Battery Indication

If the low battery symbol appears on the LCD display, it indicates that the batteries are low and need to be replaced. Replace with two new AAA batteries following the installation steps in Section 4.1.

8.2 Inconsistent or Unchanging Readings

If you experience issues with temperature readings not changing or being inconsistent, consider the following:

• Check Measurement Angle: For liquids, ensure you are measuring at the recommended 45-60 degree angle to avoid steam interference (refer to Section 5.6).
• Target Size and Distance: Ensure the target object is large enough relative to the measurement spot size at your distance (refer to Section 5.5).
• Environmental Factors: Avoid strong electromagnetic fields, explosive gases, or dusty/steamy environments as these can affect accuracy (refer to Section 2).
• Unit Switching: Verify that the temperature unit (°C or °F) is set correctly according to your preference (refer to Section 5.2).

9. User Tips

• For the most accurate readings, ensure the target surface is clean and dry.
• When measuring reflective surfaces, the emissivity setting (0.95 for this model) is fixed, so be aware that highly reflective surfaces might give slightly less accurate readings.
• Always keep the laser pointer off when not actively aiming to conserve battery life and for safety.
• Utilize the backlight feature in dimly lit areas for better visibility of the display.
