Adjusting the 10V Reference

1. Turn off power to your processor and I/O chassis.

2. Swing the field wiring arm out of the way.

3. Remove the module from the I/O chassis.

4. Plug the module into the extender card, and insert the extender card

into the I/O chassis.

5. Attach the negative lead to an analog common (pin 5, 10, 15, 20 or

21) of the wiring arm.

6. Attach the positive lead of your voltmeter to TP1.

7. To set the on-board +10V reference, adjust potentiometer R64

(Figure 6.1) until the value at TP1 = 10.0000V (+

.0002V maximum).
