Introduction to common faults and solutions of infrared thermometer
1, Output remains unchanged
Fault phenomenon: When the temperature of the measured medium increases or decreases, the output of the infrared thermometer does not change.
Possible reasons: Sealing issues with the infrared thermometer, such as not sealing properly or creating small holes during welding.
Solution: Replace the housing of the infrared thermometer to ensure good sealing.
2, Large output error
Fault phenomenon: There is a significant deviation between the measurement results of the infrared thermometer and the actual temperature.
Possible reasons:
The linear range of the newly selected infrared thermometer is inconsistent with the original one, resulting in sensitivity errors.
The infrared thermometer is not calibrated properly or has failed calibration when it leaves the factory.
terms of settlement:
Re calibrate the infrared thermometer to ensure its linear range is consistent with the actual application.
Check the calibration records and recalibrate if necessary.
3, Unstable output signal
Fault phenomenon: The output signal of the infrared thermometer fluctuates greatly and is unstable.
Possible reasons:
The temperature source itself is unstable.
The resistance of the display instrument is not strong.
terms of settlement:
Observe at room temperature indoors and monitor the output signal of the infrared thermometer with other instruments to ensure stability.
If only the instrument display is unstable, consider replacing the display instrument or enhancing its resistance.
4, Low battery level
Fault phenomenon: The infrared thermometer cannot work properly or displays low battery.
Solution: Check the battery level and replace it with a new one if it is low.
5, Environmental temperature impact
Fault phenomenon: The infrared thermometer cannot function properly in environments with excessively high or low temperatures.
Solution: Ensure that the infrared thermometer is used within the applicable ambient temperature range (such as 0 ℃ to 50 ℃).
6, Camera issue
Fault phenomenon: Inaccurate temperature measurement caused by improper installation, damage, or dirt on the lens.
terms of settlement:
Check if the lens is too far or too close to the target, or if the lens is tilted, and maintain an appropriate distance and perpendicularity between the lens and the target.
Check the lens for wear, cracks, or dirt, and replace or clean it if necessary.
7, Sensor malfunction
Fault phenomenon: Sensor malfunction or interference leading to inaccurate temperature measurement.
Solution: Check if the sensor is faulty or interfered with, and if so, replace the sensor.
