Using the LI-6400 25-3
We start with one of several functions defined by OPEN for use in AutoPro-
grams:
LPPrep
This is required for any AutoProgram which makes use of the commands LP-
Measure or LPMeasureTilStable is used. (If you donÕt use the LPPrep func-
tion prior to LPMeasure or LPMeasureTilStable , no one will slap your hand,
but you might crash the system.)
Repetitive operations can go within LPLÕs loop structure, the NLOOP ... END-
LOOP pair of keywords. The value on the stack when the NLOOP is encoun-
tered specifies the number of times through the loop. Within this structure, the
60 second delay is done by
60 LPMeasure
LPMeasure creates a New Measurements mode-like setting for a fixed
amount of time, and when it is over, the global variable lpAbort tells us if the
user wishes to abort the program. (This happens when the user presses escape
during LPMeasure . This brings up the AutoProgram exit dialog box
(Figure 25-2 on page 25-13). If the user presses A , lpAbort gets set to 1.) To
abort (if lpAbort is non-zero), we just jump out of the loop.
lpAbort BREAKIF
Data recording is done by
LPLog
which causes a record to be written to the open log file (or RAM file or comm
