The following program is similar to the preceding program except that it uses the
post-process PFAIL operation on 20 readings stored in memory. The post process
PFAIL operation is a batch operation. That is, the readings do not have to be
recalled from memory in order to perform the PFAlL operation. Also notice that the
readings must be stored before enabling the post process PFAIL operation (if not,
the MEMORY ERROR will occur).
