BI: 0.125sec
---: 0.125sec
-----------: 0.375sec
if the temperature < 37.80к(100л), the buzzer alarms “BI-BI-BI-BI-” for 10 sec, as follows:
BI --- BI---
BI: 0.5sec
---: 0.5sec
j. It will automatically power off after measurement is stable and the system is still on more than 8 min
40sec(Fsys=32kHz)
k. When measurement is over and the beep sound is terminated, if the temperature rises within 8 min 40
sec, the measurement will start again, but the к mark will not flash and the buzzer will not output also.
l. During bi sound is on 10 sec, the temperature is not measurement.
y When power off: the stand-by current Љ1µA.
y The frequency of buzzer is 6k(VSS) or 8kHz (Open or VDD) by pin option.
y Measurement to 0.1 degree at °C.
y Sensor use 503ET.
y Reference resistor is the value sensor in 37.0 °C.
y The low battery and “M” flag can not display when the temperature show Hi or Lo.
y When battery voltage is low, the battery mark “ϧ” flashes at the speed of 1Hz and the measurement
maybe not accurate. The low TEST pin connect to Vss, the measured
temperature will be the actual temperature of voltage detect: 1.35V ̈́0.05V.
y During the process of mass production, in order to adjust the reference resistance (RF), let the measured
environment. The LCD can be up or down changed, not always show the higher one.
y There are 4 kinds of stable time to be selected; 4 sec, 8 sec, 16 sec and 32 sec.
