Hardware interrupt limits
The values that can be set for hardware interrupts (high/low limit) must be within the nominal
range and overrange/underrange of the relevant measuring range.
The following tables list the permitted hardware interrupt limits. The limits depend on the
selected measurement type and measuring range.
