The instrument will change over earlier to the response defined for
overrange / underrange if the range is restricted.
Example:
Pt100 (Range: - 200 to + 850 °C). An alarm message is to be generated
for temperatures outside the range 15 to 200 °C.

On transducers with standard signal and on potentiometers, a display
value is assigned to the physical signal.
Example: 0 to 20 mA = 0 to 1500 °C.
The range of the physical signal can be 20 % wider or narrower without
generating an out-of-range signal.

Filter
0 to 0,6 to 100 s To adjust the digital input filter (0 s = filter off). 63 % of the alternations
are accounted for after 2x filter time constant at a signal step change.
When the filter time constant is large:
- high damping of disturbance signals
- slow reaction of the process value display to process value changes
- low limit-frequency (2nd order low-pass filter)
TK constant value

Measurement of the cold-junction temperature with an temperature

No function.

...
Output 12
The heater current is evaluated using a current transformer with a
standard signal output, which can be monitored by linking the analog
input with a limit comparator.
The measurement is always made when the heating contact is closed.
The measurement is retained until the next measurement.
