CHAPTER 10: Calibration
Performance Module is replaced with another of the same type, however,
calibration of the new Performance Module should be performed.
A Calibration Standard is available for convenient field calibration of
twisted-pair Performance Modules. This Standard also enables you at any
time to perform a “confidence check” on the proper operation of a
Performance Module by repeating the calibration procedure.
To calibrate a Performance Module:
NOTE
Press ESC at any time to cancel the calibration procedure.
1. Set dial to CAL.
2. Highlight PERFORMANCE MODULE in the Calibrate menu using the
arrow keys.
3. Press CALIBRATE (F4) or ENTER. The CALIBRATE PERFORMANCE
MODULE screen will appear with the displayed message “Connect To
JACK 1.”
4. Connect the SCAN-LAN VI to JACK 1 of the Calibration Standard.
(Use a Category 5 Patch Cord for connecting a Modular Jack
Performance Module to the Calibration Standard.)
5. Press START (F4) or ENTER. The message “CALIBRATING...” will be
displayed on the screen. The bar graph across the bottom of the display
will show the progress of the calibration. Press CANCEL (F1) or ESC to
cancel the calibration procedure.
6. After approximately 45 seconds, the SCAN-LAN VI will display the
message “Connect To JACK 2.” Remove the plug from JACK 1 and
insert it into JACK 2.
7. Press CONTINUE (F4) or ENTER. The message “CALIBRATING...”
will be displayed, and the bar graph across the bottom of the display
will show the progress of the calibration. Press CANCEL (F1) or ESC
to cancel the calibration procedure.
