Functional Description
The following description is for HT7510 only.
Power switch: press switch to turn the power
on or off.
When power is on: press the switch, then it will
generate a “beep” sound for 0.125 sec.
a. Displays all the segments first for 2 sec.
b. After a. shows the temperature of the last
reading for 2 sec.
c.
After b. shows L
°
C (or
°
F ) for 0.75 sec.
d.
After c. displays the measurement tem-
perature, the
°
C (or
°
F) mark will flash at a
speed of 1Hz.
e. If the temperature < 32
°
C (or 90
°
F), the
display shows L
°
C (or
°
F).
f.
If the temperature
≥
42
°
C (or 108
°
F), the
display shows H
°
C (or
°
F).
g. The display always show the higher tem-
perature during the measurement.
h. If the measured temperature does not
change for more than 16 sec, the measure-
ment is over and the
°
C (or
°
F) mark flash
stops.
i.
When measurement is over, if the tempera-
ture > 37.5
°
C (or 99.5
°
F),the buzzer alarms
“Beep-Beep-Beep---Beep-Beep-Beep---”
4 sec, as follows:
if the temperature
≤
37.5
°
C (or 99.5
°
F),
the buzzer alarms “Beep-Beep-Beep-Beep-
” for 4 sec, as follows:
for
j.
If the measurement is over 8 min. 40 sec.
the power will automatically turn off
k.
When the measurement is over and the
temperature rises within 8 min. 40 sec, the
°
C (or
°
F) mark will flash again (repeat
from step 2-d), and starts to count again
until 8 min. 40 sec.
l.
When beep sound is on for 4 sec, the tem-
perature is not measured.
When power is off: the standby current
≤
1
μ
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 503E T.
Reference resistor value (sensor in 37.0
°
C)
When battery voltage is low, the battery mark
“
” flashes at a speed of 1 Hz and the meas-
urement may not be accurate. The low voltage
detect: 2.4V
±
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 meas-
ured environment. It can be up or down, not
always the higher one.
