Field Descriptions:
Field
Values And Description
Byte 1 –
Byte 2
These two bytes represents the Firmware Version of UWBT device.
E.g. Consider the Firmware version as 1.01
Now multiply 1.01 by 100 to convert into integer and then calculate the hex
value. In this case the hex value is 0x0065
Byte 3
1 -UWBT Device
Byte 4
1 -Thermocouple
2 -RTD
3 -pH
4 -RH
Byte 5
For Thermocouple Model, the value ranges from 1 to 9 for the sensor
subtypes J, K, T, E, R, S, B, C and N accordingly.
For RTD Model, the value ranges from 1 to 2 for the sensor subtypes PT100
and PT1000.
For pH/Temp Model and RH/Temp Model the value is 0.
Byte 6 –
Byte 7
Temperature Zero Offset correction Value. This offset correction is common
for Thermocouple, RTD and pH/Temp Model (If RTD is present).
E.g. Consider user set the zero offset temperature as -1.6° F.
Now multiply -1.6 by 10 to convert into integer and then calculate the hex
value. In this case hex value is 0xFFF0.
