Calibration Set up
Follow the steps below to set up the test equipment and actuator to verify calibration or perform calibration
procedures.
Step
Action
1
Determine input type (current or voltage).
2
Set jumper W2 on main CPU board according to type of signal source. See Figure 27 on page
68 for jumper location.
3
Connect the copper leads from the signal source to the input terminals of the actuator as
shown in Figure 25.
4
Place signal source output at zero and switch power on.
5
Connect a 250 ohm resistor across the Output terminals of the actuator and connect the DVM
leads to the terminals.
