Function Description
Power sw: push switch to power on or power
off.
When power on: push the switch, then it will
generate a beep sound for 0.125 sec.
a. First displays all the segments on for 2 sec.
b.Aftera.asdescribedabove,thenshowsthe
last time measured temperature for 2 sec.
c. After b., shows L C or
F for 0.75 sec.
d.Afterc.,displaysthemeasuredtemperature,
then Cor F markwillflashata speed of1Hz.
e. If the temperature is < 32 C (or 90 F), the
display shows L C (or F).
f. If the temperature
display shows H C (or F ).
42 C (or 108 F the
g. The display always shows the higher
temperature during the temperature
measurement.
h. If the measured temperature does not
changeformorethan16sec.,themeasure-
mentisoverandthe C(or F) mark flash
stops.
i. When measurement is over, if the
temperature > 37.5 C (or 99.5 F) the
buzzer alarms

measurement is over for 8 min 40 sec.
k. When measurement is over, but if the
temperatureriseswithin8min40sec,the
C (or F) mark will flash again (repeat
from step 2-d), and starts to count 8 min
40 sec again.
l. When beep sound is on for 4 sec, the
temperature is not measured.
When power off: the standby current
1 A.
The frequency of the buzzer is 5.3kHz
Bonding option C or F
Measurement to 0.1 degree in either C or F
Sensor use 503ET
Reference resistor is the value
(sensor in 37.0 C)
Whenbatteryvoltageislow,thebatterymark
flashes at the speed of 1Hz and the mea-
surement may not be accurate. The low volt-
age detect: 1.35V
0.05V.
During the process of mass production, in or-
der to adjust the reference resistance (RF), let
test 2 be floating, the measured temperature
will be the actual temperature of the mea-
sured environment. It can be up or down, not
always the higher one.
