Parameter data records
B.1 Parameter assignment and structure of the parameter data records
Valid values for fixed reference temperatures
The values that you can set for fixed reference temperatures must be in the valid range of
values. The resolution is a tenth of a degree.
Table B- 6
Temperature unit
Celsius (default)
Fahrenheit (default)
Kelvin (default)
Hardware interrupt limits
The values that you can set for hardware interrupts (high/low limit) must not violate the
over/underrange of the respective rated measuring range.
The following tables list the valid hardware interrupt limits. The limits depend on the selected
measurement type and measuring range.
