8. Measuring in object mode
A distinction is made here between two different types of measurement. Follow
the steps below if you want to measure the surface temperature of an object,
e.g. a baby bottle or the surface temperature of the bathwater:
1. Please check that the mode switch is in the right position. Follow
steps 1 – 2, as described in Chapter 7.
2. The temperature display then goes out. On the display, you will see the object
symbol . The device is ready for the measurement as soon as the "°C"
symbol flashes.
3. Point the thermometer at the middle of the object you would like to measure
at a distance of 3 – 5 cm.
4. Press the SCAN button to start the measurement.
5. The scanning process lasts 3 seconds and the measured temperature then
appears on the blue illuminated display. The result is displayed for 5 seconds
and then the flashing "°C" symbol appears in the display. The device is now
ready for the next measurement.
If you want to measure the ambient or room temperature,
• hold the device in the room and press the SCAN button. You need not point the
device at any specific object. Thermoval baby now determines the temperature
of the ambient air. After 3 seconds, the temperature appears on the display
and the display lights up blue.
Important information for object measurement
• Due to physical surface effects, the temperature of a surface measured in
object mode can differ greatly from the real temperature.
• Inside the object, the real temperature may be distinctly warmer or colder than
the temperature measured on its surface.
• The measurement is accurate only when the measuring distance of 3 – 5 cm
between the thermometer and measured object is maintained and the sensor
lens is not clouded by condensation.
• Please make sure, before taking the measurement, that the thermometer
has been placed in the same room as the object to be measured for at least
30 minutes. In case of high air humidity (e.g. in the bathroom), the thermom-
eter must be acclimatised to the room temperature and air humidity prior to
measurement.
• Measurements above boiling water or steaming bathwater will cause the
sensor lens to become steamed up, and thus will have a strong influence on
the measuring accuracy.
• Surface measurement in object mode is not suitable for medical use or body
