1. Appearance check.
The electronic thermometer is generally small and beautiful, with smooth surface and no defects.
2. Electrical examination.
Put the switch button in the open position, check whether the display mark is consistent with the instructions, disconnect the power supply, and observe whether the correct mark is also shown, if the correct labeling is the same, and the display of the axillary temperature is basically the same, indicating that the repeatability of the electronic thermometer is good. Yes. If the display is abnormal (the temperature difference is too large), it indicates that the battery temperature of the electronic thermometer is depleted, or there is a bad contact somewhere.
3. Accuracy examination.
Press the switch button and the "188.8" mark appears on the LCD. Put the thermometer under the tongue for 1 minutes. When the "C" mark stops flashing and buzzing tone, the reading is body temperature, which is the oral temperature. Several times, the oral temperature should be the same, if not the same, the table is not repeatable, can not be selected, and do not need to do accuracy examination. If the oral body temperature is exactly the same, you can carry out the axillary temperature measurement. When the "C" mark stops flashing and has a buzz note, the reading is the body temperature under the axillary. Similarly, for several times, the temperature of the axillary body is the same. The general oral temperature is about 1 degrees higher than that of the underarm temperature. If the test of oral temperature is too much or too little, the accuracy of the electronic thermometer is not satisfactory.
4, if the electronic thermometer is placed under the tongue for 1 minutes, the "C" mark will continue to flicker, then the power of the electronic thermometer must be cut off and then the power is reconnected after 5 minutes. In general, after taking out the body temperature from the mouth, it will not flicker. If it is still flickering continuously, the meter will have problems and cannot be selected.
5, is not the regular manufacturer, the standard two types of medical equipment, there is no after-sales service, there is no telephone address, and other external packaging information, can also be related to the company's official website.
