Viewing the operating parameters
The upper display is a six-character display, four of which show the value of the PV during normal
operation.
 The lower display is an eight-character display. During normal operation, you can view various
operating parameters. Press the LOWR DISP key to scroll through the operating parameters listed in
66HTable 5-7.
 The lower display shows only those parameters and their values that apply to your specific model and
the way in which it was configured.
 You can configure the lower display to scroll through the items in 67HTable 5-7 at an interval of 1, 2, or 3
seconds. Refer to subsection 3.17 Options Set Up group, function prompt “SCROLL” to make your
selection.
Pressing the LOWR DISP key will freeze the lower display at the presently viewed item; pressing it
again will advance to the next item and scrolling will resume.
 Pressing ▼while pressing LOWR DISP will scroll backwards.
For recorders with two controllers (both enabled) remember that any controller-related values displayed
correspond with the lighted CHN indicator — “1” means that the values apply for Controller #1 and “2”
means that the values apply for Controller #2.
