With the continuous advancement of science and technology, high-precision handheld infrared thermal imagers have become an indispensable device in the field of modern detection. It has the characteristics of high precision, high sensitivity and easy portability, and is widely used in electricity, machinery, metallurgy and other industries. So, how to use a high-precision handheld infrared thermal imager? The following will introduce it to you in detail.
Instrument operation
1. Handheld use: Lay the instrument flat, press the start button lightly, and after the instrument starts, you can pick up the instrument for use. For first-time users, it is recommended to calibrate the sample first to ensure the accuracy of the data.
2. Determine the measurement distance: Before measurement, the measurement distance and field of view angle must be determined to ensure the accuracy of the measurement data. At the same time, it should be noted that the focus mode of the equipment needs to be adjusted at different distances to ensure the effectiveness of the measurement.
3. Shooting settings: The equipment should be adjusted before shooting. The temperature range of the instrument shooting can be set, and different color band expressions can be selected. For occasions requiring high precision, single-point temperature measurement can be set to quickly and accurately measure the temperature.
Equipment maintenance
1. Protective measures: When using, the operating procedures should be strictly followed to protect the equipment from exposure to sunlight, lightning strikes, vibrations, etc. After use, the equipment should also be maintained, the lens and instrument housing should be cleaned, and dust and moisture should be avoided to avoid damage to the equipment.
2. Storage method: You can choose cloud storage or local storage. It is recommended to delete useless pictures in time after storing data to avoid wasting storage.
3. Calibration: During use, thermal imaging may be inaccurate. In this case, calibration can be used to adjust to improve the accuracy and stability of temperature detection.
Night use
1. Light adjustment: In low-light environments, you can turn on the device's built-in night vision function (if any) and irradiate weak light to reflective objects in the scene. You can also shoot with a higher ISO sensitivity, but the quality may be affected.
2. Appropriate scale: When using, you need to adjust the brightness, contrast and other parameters of the thermal imaging display according to the scene. At the same time, you also need to choose the appropriate thermal imaging ribbon according to the characteristics of the scene.
The above are the usage and precautions of high-precision handheld infrared thermal imagers. During use, pay attention to protecting the equipment and operate it correctly to ensure the accuracy of the test data.
