Appendix B. Calibration and Testing with PanaView
44 DigitalFlow™ XGM868i Service Manual
B.3 Calibrating Slot 0 Analog Outputs (cont.)
3. Double-click on either Output A or Output B to open the Analog Output menu. (Output A will be used as an
example in this manual.)
IMPORTANT: The procedure for calibrating Output B is identical to that for calibrating Output A. However, when
calibrating Output B, be sure to reconnect the ammeter on terminal block J1. See Figure 11 on page 43 for
the correct pin numbers.
4. Double-click on 4 milliamps to calibrate the low end of the output range.
5. Double-click on 4 mA UP or 4 mA DOWN to adjust the ammeter reading UP or DOWN, until a 4 mA reading is
achieved, or
Double-click on 4 mA Numer, and directly enter the mA reading in the right pane.
6. Once you have achieved a 4 mA reading, double-click on either 4 mA STORE to store the calibration, or on 4 mA
ABORT to exit the menu without storing the calibration.
Note: If the ammeter reading cannot be adjusted within 5.0 A of the 4 or 20 mA setting, contact the factory for
assistance.
7. PanaView returns to the Analog Output window. Double-click on 20 milliamps, and repeat steps 5 and 6 to
calibrate the high end of the output range.
Note: Skip the following prompt, if linearity testing of the output will not be performed at this time.
8. Double-click on % Test to test the linearity of the currently selected analog output.
9. Check the ammeter reading at 50% output. Then, enter a different output (0-100%) and double-click on percent.
Check the ammeter reading at this setting and click [Exit Page] when done.
Table 8 on page 45 lists the expected ammeter readings at various % Full Scale settings, for both 4-20 mA and 0-20
mA scales. Refer to this table to verify the accuracy of the ammeter readings taken above.
