IMPORTANT NOTE: For illustrative purposes, the AI 1 is calibrated for an external device
with a measurement range value of 100.
To calibrate the analog input:
Make sure the AI is set to voltage mode.
Restore power to the XSeries
Make sure that the calibrator is set to the voltage signal type.
Connect the PC or laptop running PCCU32 to the XSeries
Turn the calibrator on to supply the signal.
Click the Calibrate icon on the PCCU toolbar to display the Calibration screen.
Click the Onboard I/O folder on the navigation tree to expand it. Then, click Analog
Inputs. The Analog Input 1-tab displays.
Click another AI tab, if necessary, to calibrate. This example displays AI 1 (the Analog
Input 1 tab is the default displayed).

Select either the 3 Point or 5 Point calibration from the Calibration drop-down list.
Verify that only the Zero Input and Low-Cal Point buttons are enabled and highlighted.
The system enables the buttons in the order required for the calibration.
Click the Range field. The Analog Input Range dialog box displays.
Type the external device measurement range into the entry field and click OK. The values
in the Target column of the table update to reflect this range.
Click Low Cal Point. The Enter Low Calibration Value dialog box displays with the target
low value automatically calculated. For example, for the range value of 100, the value is
0.000.
Adjust the calibrator to apply the low value of the signal range. For example, if the signal
range of the external device is 1 to 5 Vdc, apply 1 Vdc.
Observe the value in the Current Reading field. When the value stabilizes, click OK.
