Impedance Calibration
Impedance calibration should be performed on a periodic basis in
order to maintain maximum accuracy. Impedance calibration is
most sensitive to temperature changes. Allow the main unit to
stabilize to the operating environment before performing the
calibration procedure. Calibration should be performed whenever
a different Performance Module is installed.
To calibrate Impedance:
1.
Set the dial to CAL.
2.
Highlight Impedance in the Calibrate menu by using the
arrow keys.
3.
Press CALIBRATE (F4) or ENTER. The Calibrate
Impedance screen will appear with the displayed message
“Connect to Jack 1”.
4.
Connect the LANcat to JACK 1 of the Calibration Standard.
(Use the supplied 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.
When finished, the screen returns to the CALIBRATE menu.
