To exit from the main menu and return to run mode, press and hold both buttons for 2
seconds until OK is displayed on the screen.
After two minutes of inactivity from the front buttons when the main menu (or a sub-
menu) had been accessed, a timeout will occur, and the unit will automatically return to
run mode.
6.2 Output Span and Output Zero (1. OUT SPAN and 2. OUT ZERO)
These menu options allow the IWR-Port to learn the output span and zero values if there
is an output fitted to the IWR-Port. Default output values will make the DAC output 4 to
20 mA or 2 to 10 V for the voltage option
.

6.3 Display Scaling Values Adjustment (3.DSV Cc Pp, 4.DS span,
5.DZ zero)
The display can show a scaled numerical value for each parameter of each channel.
Scaling values can be adjusted between –999 and 9999. The default scaling values are 0
to 100. For all channels, all 8 parameters can be changed even if the channel is not used,
or some of the parameters are not used, or autoscaling is on (see 6.19).
For channels with digital outputs, the display scaling values can be used to configure
setpoints if the digital output is linked to following an analog input. The setpoints are
compared to the analog input value to switch the digital output on and off. The setpoints
are configured as percentage values (0-100%). The span value is the on setpoint and the
zero value is the hysteresis. The off setpoint is calculated by adding the span and
hysteresis together.
The hysteresis value can be positive or negative. If hysteresis is negative, the digital
output switches on (when the analog value it is following is) above the on setpoint and off
below the off setpoint. For example, if the span is 50% and zero is -10%, output switches
on above 50% and off again below 40%.
If hysteresis is positive, the digital output switches on below the setpoint and off above
the off setpoint. For example, if the span is 50% and zero is 20%, output switches on
below 50% and off again above 70%.
