Development of soldering iron head for soldering and tinning
1. When using the infrared thermometer, be careful not to irradiate the eyes of the person being tested, but test on the forehead, and make sure that the forehead is not covered by hair, hat or covered by dust or sweat.
2. Pay close attention to the information on the display of the instrument, when the display shows
When the battery is low, replace the battery immediately, otherwise it will affect the normal operation of the instrument. Pay attention to the M measurement mode displayed on the display screen. If it is the measurement object surface mode, press the switch button to switch to the human body temperature mode.
3. When the person under test is found to have symptoms of cough and fever, the measurement should be repeated three times, and the highest value should be taken as the final measurement value, and the temperature unit displayed on the display should be noted. Generally Celsius (T ) is more versatile and intuitive than Fahrenheit (F ), so take care to switch from Fahrenheit to Celsius. To ensure that the instruments used are qualified, the infrared thermometers configured by each unit and department should actively apply for calibration to the local legal metrological verification institution before use; the measurement standard devices used in calibration, such as black body furnaces, should be reliable and effective. Value traceability = Only by using qualified infrared thermometers can effective screening of febrile patients in the crowd be carried out.
Careful storage to ensure the cleanliness of the instrument The non-contact infrared thermometer is designed to be small and exquisite. When using it, try to handle it with care, and do not break or damage the instrument due to negligence. Due to the frequent use of the instrument, it is difficult to keep it clean all the time. When the detector of the instrument is found to be dirty, wipe it with a cotton swab dipped in 9 5% absolute alcohol, and be careful not to let the liquid flow into the detector. The cleaned thermometer should be stabilized in the use environment for a sufficient time according to the instruction manual before it can be used again.
The above precautions are based on the author's experience in work. I hope to a certain extent, it can help the front-line epidemic prevention and investigation staff to effectively monitor the tested personnel, achieve early detection, early control, and early treatment, and block the spread of the virus in time. effectively protect the public
health and life safety.
