To calibrate the input module, follow this procedure.
1. Disable system and user power.
2. Disconnect the field wiring.
3. If you are using a Euro-extender card (Euroboard):
Remove the module from the base.
Insert the extender card into the I/O slot that the module occupied. You
may use a Schroff, Inc. Test adapter board.
Insert the module into the extender card (Figure 3-2). This provides
access to the calibration potentiometer and input range select jumper.

If you are not using a Euro-extender card:
Remove all I/O modules from the base.
Select voltage input range as shown in Figure 3-2.
Move the analog input module to the far left (I/O slot 1) to allow
maximum space to reach and adjust the potentiometer.
4. Power up the system and allow the module to reach its operating
temperature (usually about 30 minutes, if cold).
5. Connect a programming device to the controller.
If you are not using a Euro-extender card, configure the analog input
module in slot 1.
