For this, you press the button on / recall of the unit. All light and seeing a 00.0 ° C poster with the logo of a top right ear. We introduce the thermometer in the ear and press the scan button on the top. A beep will be heard almost immediately that marks the end of the socket. We can make a new one in stride but it takes about 10 seconds until the logo with the ear in the upper right reappears. You can press the button on / recall and a number appears (9 to 1) with a number. This is the last catches (so the last 9 maximum). No off button but an automatic sleep function after one minute.
The very big plus point of this thermometer is the speed of decision (almost instantaneous). The playful and quick side appeals to children but also to adults! It really does not take much space and the battery used easily commercially (the same as in many watches) for future replacement. The manufacturer gives 2000 taken before the battery change (a battery logo is supposed to appear on the thermometer when the battery is low). The reverse of this ultra fast setting is a random precision. If the thermometer is loose, the temperature will be fantastic (I had the right to the 35.2 ° C for example). Likewise, we find differences from one ear to the other of the order of a few tenths. However, it remains convenient to know instantly if a fever or not. But we will double making for greater safety, which always proves much faster than with a traditional thermometer in the end. I am quite satisfied.
