OPERATION
Sequence file setup requires the user to specify a large number of parameters in a series
of data entry screens described below. For a summary of the sequence definition
requirements in the order they are edited, see PRINCIPLE above.
To access the Sequence file building function, press
the SETUP menu key and then 3Sequence. The
display is:
File sequence:
1Edit 2View
1Edit allows a sequence file to be edited.
2View allows a sequence file to be viewed only. If 2View is selected, the values shown in the
following screens cannot be edited. The instructions below assume that 1Edit is selected.
When defining a sequence, the ESCAPE key can be used to back through the definition and
reenter information until the numerical value of the pressure points is being defined. Then
ESCAPE will go to a "Save As" screen in which the sequence as edited so far can be saved
to a sequence file number. This allows information in the beginning of a sequence file to be
edited without having to go through the entire sequence definition.
The next display is:
1. Entry field for the file number of the sequence to be edited.
Edit sequence:
nn
Enter the desired sequence file number.
Up to 20 sequence files can be setup (address numbers 01 through 20).
The next selection determines the reference transducer that will be used:
1. Indication of the sequence file number that is currently being
edited.
Use ref sensors
1Hi 2Lo Seq01
Select the reference transducer that is to be used when running this sequence.
The next selection specifies the range of the selected
reference transducer that is to be used for this
sequence:
Use rnge 1Rng1 2Rng2
3Rng3
Select the range (see Section 3.1.2.5) that is to be used when running this sequence.
The next selections specify the pressure unit and
measurement mode in which the sequence pressure
points will be defined:
Select pressure unit
<Next Screen> Seq01
Press ENTER to proceed to the pressure unit and measurement mode selection. These will
operate in the same manner as when the UNIT function is used (see Section 3.2.2). To change
the pressure units available, use PresU under the SPECIAL menu (see Section 3.4.1).
