Field
Values And Description
Byte 16 –
Byte 17
High Alarm (Refer Note: 1)
E.g. for pH Model
Consider user set the low alarm ph value as 12.50
Now multiply 12.50 by 100 to convert into integer and then calculate
the hex value. In this case hex value is 0x04E2.
E.g. for RH Model
Consider user set the low alarm ph value as 80.4
Now multiply 80.4 by 10 to convert into integer and then calculate the
hex value. In this case hex value is 0x0324.
Byte 18 -
Byte 19
These bytes are common for Thermocouple Model, RTD Model, RH/
Temp Model and pH/Temp Model sensor temperature Dead band
value.
E.g. Consider user set the temperature dead band value as 10.0° F.
Now multiply 10.0 by 10 to convert into integer and then calculate the
hex value. In this case hex value is 0x0064.
Byte 20 –
Byte 21
Dead band value for pH/RH
Dead band for pH/RH Model has two byte values as described below
E.g. for pH Model
Consider user set the dead band value as 10
Now multiply 10 by 100 to convert into integer and then calculate the
hex value. In this case hex value is 0x03E8.
E.g. for RH Model
Consider user set the dead band value as 13
Now multiply 13 by 10 to convert into integer and then calculate the
hex value. In this case hex value is 0x0082
Byte 22
Bit 2 to Bit 0
001 – Engineering unit ‘F’
010 – Engineering unit ‘C’
011 – Engineering unit ‘R’
100 – Engineering unit ‘K’
Bit 3
0 – RTC NOT updated
1 – RTC updated
