9. CALIBRATION AND UPGRADING
The LANcat performs several types of calibrations: NVP
calibration, Remote Unit calibration, Performance Module
calibration, Impedance calibration, Resistance calibration, and
main unit calibration.
NVP Calibration
A default Nominal Velocity of Propagation (NVP) value is
preselected in the LANcat depending on the cable test standard
selected. More precise NVP values can be set using one of the
following procedures. NVP calibration using a section of the actual
cable to be tested is the more accurate of the two procedures.
USING A KNOWN LENGTH OF CABLE
To measure and save the NVP of a known length of cable, perform
the following steps.
1.
Set the dial to CAL.
2.
Select NVP from the calibration menu and press CAL (F4) or
ENTER.
3.
Press arrow keys to change the cable test standard and press
SAVE (F4) or ENTER.
