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.

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.
