The MediaChecker will now test according to the cable
characteristics defined by the factory settings for the
cable selected. However, cables coming from different
batches or manufacturers can have characteristic

calibrate the MediaChecker to a known length of the
cable to be tested. See "Calibrating the MediaChecker to
a Cable" on page 10.
