The funny number generator of Tristar

This has several additional features is all well and good, but if not even the actual function, the temperature measurement works then ... well

Basically there are two ways to measure fever.
Man holding the device to his forehead and pressed his forehead key

Or

You put the tip of the device without attachment! (Unless you have very very big ear inputs) in the ear, pushing the ear button.

After about one second makes the device beeps and displays a temperature.

I feel for some time very hot, because I have a cold, so I reach for the end method.
Once recognized and Beep!

35.5 ° C ... how? that can not be! again
Beep ... 36.6 ° C that would be ok now normal temperature
Beep 42.2 ° C ... well I'm not dead

Then just yet ears function

Beep 36.2 ° C

Conclusion ...
Anyone looking for a number generator is well served here. Who wants a reliable measurement should rather resort to a more expensive product or the good old analog meter.
