Field
Values And Description
Byte 8 – Byte
9
Data bytes for pH/RH Model is calculated as shown in the example.
(Refer Note: 1)
E.g. for pH Model
Consider user set the pH value as 12.01
Now multiply 12.01 by 100 to convert into integer and then calculate
the hex value. In this case the hex value is 0x4B1.
E.g. for RH Model
Consider user set the RH value as 25.2
Now multiply 25.2 by 10 to convert into integer and then calculate the
hex value. In this case the hex value is 0x00FC.
For Temp Model these bytes are always Zero.
Byte 10 –
Byte11
These bytes are common for Thermocouple Model, RTD Model, RH/
Temp Model and pH/Temp Model temperature low alarm value.
Note: RH/Temp Model and pH/Temp Model have temperature
measurement for temperature related compensation.
E.g. Consider user set the low alarm temperature as 100.0°F.
Now multiply 100.0 by 10 to convert into integer and then calculate the
hex value. In this case hex value is 0x03E8.
Byte 12 –
Byte 13
Low Alarm (Refer Note: 1)
E.g. for pH Model
Consider user set the low alarm ph value as 10.50
Now multiply 10.50 by 100 to convert into integer and then calculate
the hex value. In this case hex value is 0x041A.
E.g. for RH Model
Consider user set the low alarm ph value as 30.5
Now multiply 30.5 by 10 to convert into integer and then calculate the
hex value. In this case hex value is 0x0131.
Byte 14 –
Byte 15
These bytes are common for Thermocouple Model, RTD Model, RH/
Temp Model and pH/Temp Model temperature High alarm value.
Note: RH/Temp Model and pH/Temp Model have temperature
measurement for temperature related compensation.
E.g. Consider user set the High alarm temperature as 100.0° F.
Now multiply 100.0 by 10 to convert into integer and then calculate the
hex value. In this case hex value is 0x03E8.
