5.7.1 General guidelines
The 746 VA Trace Analyzer can be used for the free programming of the sequence
of voltammetric determinations with the aid of program instructions, the associated
parameters and a line time which can be set to any value. The two following dialog
pages are available for the entry of these instructions:
"OP.SEQUENCE" Main program with call-up of the segments
"SEGMENTS" Max. 8 segments for measured value recording
(sweeps, one sweep allowable per segment) or macros
Each program instruction is located on an instruction line with the following basic
structure:
Instructions t/s Main parameters Auxiliary parameters
––––––––––––– ––––– ––––––––––––––––––––––––– –––––––––––––––––––––––––
## .. DCTMODE ..... t.step ........s t.meas ........s
The following rules apply to the basic elements of the instruction line (see also sec-
tion 5.6.1 and section 5.6.2):
Line number The lines are numbered consecutively on entry of the instruc-
tions. Maximum 99 instruction lines are possible on the
"OP.SEQUENCE" page, maximum 29 instruction lines per
segment on the "SEGMENTS" page.
Line attribute Each instruction line can be optionally provided with one of the
following attributes:
C Calibration; the marked instruction line is executed only
when the program run mode is set to
Run mode =
calibration
D Determination; the marked instruction line is executed
only when the program run mode is set to
Run mode =
determination
.
! Inactive line; this line is not executed.
@..@ Inactive range; the range between the two lines
marked by @ is not executed.
