Greetings Alan,
Thanks partially to the tips I got from your documentation I understand the calibration procedure quite well now. It is just that the next step in the procedure following "Note 6" that involves the CH0 cable (Note 11) is to install the OPEN male connector on CH0. This requires the female-to-female barrel to be connected to CH0 not CH1. The connection of a barrel connector to CH1 is mentioned later in "Note 13" for the LOAD test which infers it does not already have the barrel connector installed as requested in "Note 6". It just appears that it is just a simple typo in Note 6 that should state CH0 instead of CH1.
I hope this info is helpful and thanks again for the great documentation effort!
