point of the data is three. temperature that is higher than 39.9℃ lower than -20.5℃ should alarm.
The parameter settings should as following.
The range settings and alarm limit settings should take care of the decimal point digits setting.
"Analog signal types" used for configure analog signal type(voltage or current). If the type
voltage, "Top range corresponding to voltage(uV) or Current output (nA)" is 4500000, This means
4500000uV = 4.5V,
"Low range corresponding to voltage(uV) or Current output (nA)" is the
same. If the type is current, "Top range corresponding to voltage(uV) or Current output (nA)" is
4500000, This means 4500000nA = 4.5mA,
Current output (nA)" is the same.
Command: AT+RTUADCDECIMALy=x
Explanation: set the number of decimal point.
Parameter:
y range 1~8, corresponding to analogl input channel 1~8. x range 0-255 ，
number of decimal point, 0 mean no decimal point, 1 mean one decimal point.
Example:
AT+RTUADCDECIMAL1=0
Command: AT+RTUADCFULLVALy=x
Explanation: set top range(the value can be negative).
Parameter:
y range 1~8, corresponding to analogl input channel 1~8. x range -2147483648
to 2147483647，this value related to the decimal point.
Example:
AT+RTUADCFULLVAL1=100
Example:
AT+RTUADCFULLVAL1=-100
Command: AT+RTUADCZEROVALy=x
Explanation: set low range(the value can be negative).
Parameter:
y range 1~8, corresponding to input channel 1~8. x range -2147483648 to
2147483647，its value related to the decimal point.
Example:
AT+RTUADCZEROVAL1=100
