1) Calculate the difference between the full-scale and the begin scale values
(Span).
2) Refer to the "Input range table" and determine in the column " SPAN "
where the calculated value is included. Determine in the column "ZERO",
the range of value where the zero scale value is included. In the line
obtained with the combination, is shown the DIP-switches configuration.
3) Remove the protection plastic cap.
4) Set the switches as indicated.
5) Connect on input a Pt100 simulator or a fixed resistance value
corresponding to the resistive value provided from the Pt100 sensor at the
selected temperatures.
6) Set the simulator at the minimum temperature or connect a fixed
resistance value corresponding to the zero value.
7) Regulate the output value at 4 mA by the "ZERO" potentiometer .
8) Set the simulator at the maximum temperature or connect a fixed
resistance value corresponding to the span value.
9) Regulate the output value at 20 mA by the "SPAN" potentiometer .
10) Repeat the operation from the step 6 to the step 9 until the output
values are accurate ( typical 3 attempts required ).
Example of configuration: -30/200 °C.
Span => 200°C - (-30°C) = 230°C;
Input switches configuration: Off, Off, Off, Off.

INSTALLATION INSTRUCTIONS
The device DAT 1111 is suitable for direct DIN B in-head mounting. The
transmitter must be fixed inside the probe by the proper kit.
By apposite stirrup, provided on request, it is possible to mount the device
on DIN rail in compliance with EN-50022. It is necessary to install the
device in a place without vibrations; avoid to routing conductors near
power signal cables .
