During Use; Measuring In The Ear - Beurer FT 55 Gebrauchsanweisung

6. During use

Always ensure that the sensor is clean and undamaged. Switch on the thermometer with the " " button.

6.1 Measuring in the ear

After a brief self-test and two short beeps, the thermometer is ready to measure the temperature in your
ear. The infrared thermometer is in „ear thermometer" mode. This is indicated by the symbol .
As the ear passage is slightly curved, you have to pull the ear slightly up and backwards before inserting
the sensor tip. This is particularly important so that the sensor tip can be pointed directly at the eardrum.
Insert the sensor tip carefully and press the "SCAN" button for 1 sec.
The end of the measuring time is signalled with a long beep. Release the "SCAN" button. You can now
read off the temperature measured. The LED is also illuminated according to the test result: a green LED
indicates that body temperature is within the normal range, but a red LED lights up with measured values
over 37.5 °C, i.e. it is a fever alarm.
The thermometer signals with two short beeps and the cessation of flashing of the ear symbol " " that
the unit is ready to continue measurement.
6.2 Saving the temperatures measured
The temperature last measured, i.e. only the last temperature of a series measured, is saved automatically as soon as the
thermometer is switched off. There are 9 memory locations available for this.
You can call up the last temperature measured with the " " button. The date and time are also shown. The LED does not
support any requests for stored measured values. If you continue to hold down the " ", you will enter a special measuring
mode, in which the thermometer will not make a correct measure ment. In this event, allow the thermometer to switch off
automatically after about 1 minute and then switch it on again.
6.3 Surface temperatures
When you want to measure surface temperatures with this infrared thermometer, you must change to the "SCAN" mode.
With the thermometer switched on (Ear thermometer mode) keep the " " button depressed and at the same time press
the "SCAN" button. This mode is indicated with the symbol. If you keep the "SCAN" button depressed, the surface
temperature measured is continuously displayed. You can apply the sensor tip directly to the surface to be measured or
measure at close range (do not immerse in liquids).
