LESSON 3
NOTES GRAPHING PIDS
The graphing capability of NGS allows you to make visual
comparisons between closely related PlDs, to determine
whether or not their interaction is correct. It also allows you to
see a “glitch” that is not obvious on the table format.
Just as with the table display, up to four PlDs can be selected
for graphing, but only two at a time can be displayed. When the
graph display appears on screen, the names of the two
currently selected PlDs will appear - one on the right and one
on the left . If more than two PlDs have been selected for
viewing, you can change what is displayed on screen by using
the numeric keypad.
To change the left-hand PID, push number 2 on the numeric
keypad.
To change the right-hand PID, push the number 9 on the
numeric keypad.
The graph display screen displays a section of the recording
that represents approximately 25 seconds. The PlDs currently
being viewed are displayed to the left and right sides of the
screen. There are three sets of numbers also located to the
left and/or right side of the screen. These numbers refer to the
following:
The top number represents the value of the PID at the
MAXIMUM of the recording.
