display
LCD displays “L °C” if the measured temperature is
below the minimum of measurement range.
LCD displays “H °C” if the measured temperature is
below the minimum of measurement range.
LCD displays “Er1”if the temperature measurement
circuit is abnormal (fault of SENSOR or the
temperature measurement circuit), or the ambient
temperature exceed 50°F-104°F (10°C~40°C).
There shall be “ErC” if the calibration process is not
completed or EEPROM is abnormal.

The normal body temperature
range slightly varies with age
and gender. Generally,
newborns or children have
higher body temperatures than
adults, and adults have higher
body temperatures than the
elderly. Women's body
temperatures are
approximately 0.3°C (0.5 °F)
higher than men's.

Body Temperature
You can take a body temperature via the forehead, ear canal, armpit,
mouth or rectum. The temperature measured at different parts of the
body may differ slightly.
Body Part Normal Temperature Range
Forehead
96.44°F-100.04°F
(35.8°C–37.8°C)
Ear canal
96.44°F-100.4°F
(35.8°C–38.0°C)
Mouth
95.9°F-99.5°F
(35.5°C–37.5°C)
Armpit
94.46°F-99.14°F
(34.7°C–37.3°C)
Rectum
97.88°F-100.4°F
(36.6°C–38.0°C)
Variation in body temperature
Normal body temperature
varies by the time of day and is
also affected by external
factors.
The body temperature of an
individual is the highest
between 2:00 a.m. and 4:00
a.m. and the lowest between
2:00 p.m. and 8:00 p.m. An
individual's body temperature
typically changes by less than
1°C (1.8 °F) each day.
