1. Function Description Power Switch Press to turn on or turn off the power. Operation Procedure Turn on the power: When press the switch, the system will sound one “beep”. a. At first the system will display all LCD signals about 2 seconds. b. Following step a, select unit status ℃ or ℉. c. Following step b, it depends on the memory function. If the memory function exists, then jump to step if no memory function, the system will display 36.50℃ instead of the memory symbol, then jump to step i. d. Following step c, if the memorized temperature is between 32 ℃~43℃, the system will display the last time measured temperature value about 3 seconds and the memory symbol; if it is out of the range (<32℃ or >43℃), the system will display 36.50℃ and not display the memory symbol. e. Test the resistance reference to see whether it is normal or not. If it is normal, the system will display 37.00℃ about 1 second, then jump to step f; if it is abnormal, the system will display Err and recycle in step e. f. Display the highest measured temperature value. In the meantime, ℃ signal will flash with frequency about 1Hz. g. If the temperature is lower than 32.00 ℃, the system displays Lo ℃. ℃, the system displays Hi ℃. i. If the temperature is between 32.00 ℃ ~ 43.00℃, the system will display the highest measured temperature value. j. If the temperature keeps unchanged over 8 seconds, the temperature has reached the desired stable reading. The measurement is over and ℃ signal will stop flashing. k. If fever warning is enabled, jump to step l; if not , the system will beep one sound and jump to step m. l. When the temperature is higher than 37.50 ℃, the beeper will sound “beep-beep-beep---beep-beep-beep---” about 4 seconds. The sound would be as follow: Beep(0.125 seconds ) ―― (0.125 seconds ) Beep(0.125 seconds ) ―― (0.125 seconds ) Beep(0.125 seconds ) ―――― (0.375 seconds ) 4 times When the temperature is lower than or equal to 37.50℃, the beeper will sound “beep-beep-beep-beep-” about 4 seconds. The sound would be as follow: ―― (0.5 second ) Beep(0.5 second )) m. After measurement is over, if the temperature keeps unchanged for 5 minutes, the system will beep one sound and turn off automatically. n. If the temperature changes (larger than or equal to 0.05 ℃) within 5 minutes, ℃ signal will flash again (repeat step f), then start to recount 5 minutes. o. When beeper sounds (within 4 seconds proximately), the system will not measure temperature. Power off The system will enter sleep mode. The current consumption is 1μA. Buzzer frequency The Buzzer frequency can be selected with external pin to be 4kHz or 8kHz. Measurement Resolution The smallest measurement resolution for ℃ is 0.01. Sensor Type The sensor type uses 503ET. FORTUNE' Properties For Reference Only

Resistance reference value Resistance reference value is the thermistor resistance at 37.00 ℃. Others ” flag won’t display.  During production in the factories, TEST pin is shorted for adjusting reference resistance value (R F). In this situation, the temperature reading is the temperature of the test environment (such as the temperature tank). The display will jump up or down, and won’t keep the highest value.
