10.4.4 Set temperature deviation - F3
Press the button “set” for 3 seconds, F1 is disp-
layed on the screen; shortly press the button “set”
for 2 times, F3 is displayed on the screen. Under
F3, the temperature increases 0.1
℃
/0.1oF if the
button “+” is pressed for one time. The tempera-
ture decreases 0.1
℃
/0.1oF if the button “-” is pre-
ssed for one time. The factory-leaving default is
0
℃
(0oF), the temperature correction range is -3
℃
~ + 3
℃
. If the season or environment changes, the
measurement accuracy can be improved by calib-
rating the compensation of temperature correction.
For example: If the measurement temperature is
36.2
℃
while the actual temperature of the object
to be measured is 37
℃
, get into F3 to adjust the
deviation, with a rise of 0.8
℃
. After the setting,
the measured temperature can be the same as the
actual temperature of the object.
10.4.5 Set the warning tone - F4
Press the button “set” for 3 seconds, F1 is display-
ed on the screen; then shortly press the button
“set” for 3 times, F4 is displayed on the screen.
Under F4, press the button “+” to open the warn-
ing tone and press the button “-” to close the war-
ning tone. The factory-leaving default for warn-
ing tone is “OFF”.
10.5 Reference of body temperature
10.5.1 Different ranges of normal temperature at
different ages
In one day, human's temperature changes from
time to time, which also influences by external
factors, like age, gender, skin color and thickness
etc. Please refer to the table here below for the –
ormal temperature range at different ages.
Note:
The temperature of female is different from
the temperature of male. Normally, female tempera-
ture is 0.3
℃
higher than the male. At the time of ovu-
lation, the temperature of female will be increased
