Functional Description
y
Power SW: push PSW switch to power on or power off.
y
When power on: push the switch, a "BI" sound for 0.125sec will be generated.
a.
b.
c.
The LCD firstly all segments are on about 2sec.
After a. LCD shows the last-time temperature about 2sec. (If the memory function is optioned)
After b., LCD shows the self-test temperature (37.0±0.1
к
) about 1 sec. The
к
or
л
mark will flash at
the speed of 1Hz.
After c., LCD shows the higher measured temperature always, the
к
(
л
) mark will flash at the speed of
1Hz.
If the temperature < 32.0
к
(or 90.0
л
), the display show Lo
к
(or Lo
л
).
If the temperature
43.0
к
(or 109.9
л
), The display show Hi
к
(or Hi
л
).
The LCD always show the higher temperature during the temperature measurement.
After power on, the measurement time is over 16 sec and the measured temperature does not change
within the stable time, the measurement will be over and the
к
(
л
) mark flash stop.
i. For JA31106, when measurement is over and if the temperature
37.8
к
(100
л
). In this case the
buzzer alarms “BI-BI-BI--- BI-BI-BI---” for 10 sec, as follows:
BI --- BI --- BI ---------- BI ---
