DigitalFlow™ XGM868i Service Manual 45
Appendix B. Calibration and Testing with PanaView
B.3 Calibrating Slot 0 Analog Outputs (cont.)
If the linearity test readings are not within 5 A of the values listed in Table 8, check the accuracy and wiring of the
ammeter. Then, repeat the low and high end calibrations. If the analog output still does not pass the linearity test,
contact the factory for assistance.
10. Double-click on Exit Function to return to the Calibration menu. Then choose another output to calibrate or click
on [Exit Page] to leave the Calibration/Test menu.
This completes calibration of the Slot 0 analog outputs. Proceed to the appropriate section to calibrate additional
inputs/outputs.
B.4 Calibrating Slot 1 Option Cards
To calibrate any option card installed in Slot 1 of the XGM868i, enter the Calibration/Test menu as shown in Figure 10
on page 42.
1. In the center pane, double-click on Slot 1.
Note: The Slot 1 option only appears in the center pane if an option card has been installed in this slot.
Notice that all of the available outputs (usually four) appear at the above prompt. The desired type of output may
appear as the A and B output pair and/or as the C and D output pair. Simply select the appropriate output for calibration
and/or testing. For clarity in this chapter, the desired outputs are always placed in the A and B positions, and the C and
D positions are not specifically listed. In addition, Output A is always used as an example. Proceed to the appropriate
sub-section for specific instructions, and substitute the correct output letter for the “A” shown in the procedures.
