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 measu-
ring 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).
Note that the displayed temperature is the measured and not the adapted ear surface temperature. It is not the same as
the ear temperature.
6.4 Ambient temperature
After the measurement, the thermometer automatically switches to standby mode after about 1 minute, but only if the
time has been set. This mode is identified by the symbol and the ambient temperature is shown continuously.
If you want to use the thermometer to measure the ambient temperature, it should be positioned so that the measurement
is not influenced by solar radiation or other influences such as cold draughts from air-conditioning systems. In addition to
the ambient temperature, which is updated once every minute, the date and time are displayed alternately.
6.5 Changing the temperature unit
You can display the temperature in degrees Celsius (°C) or degrees Fahrenheit (°F). With the thermo meter switched off
or in standby mode, select the unit by holding down the “SCAN” button and at the same time pressing the “ ” button.
Keep the two buttons depressed until the temperature unit changes. All stored temperatures are displayed in the new
temperature unit.
