Appendix C: TS100 Performance Checks
NOTE: The setup consists of two 10–ft test leads plus the 1000–ft cable. The instrument is set to zero distance at the end of the test leads, which negates the leads on
the selected port. However, the instrument is not using the test leads on the other
port for this particular test, so it will see the total cable length as 1010 feet. If
your test cable is a different length, add the cable length plus 10–ft test lead.
