PCMBOAT5.PAS*************************************************************
**
File: PCMBOAT5.PAS
Author: B. Spuida
Date: 1.5.1999
Revision: 
1.1 
PCM-DAS08 and -16S/12 are supported.
Sorting routine inserted.
Set-files are read in and card as well as
amplification factor are parsed.

1.1.1
Standard deviation is calculated.

1.1.2
Median is output. Modal value is output.

1.1.4
Sign in Set-file is evaluated.
Individual values are no longer output.
(For tests with raw data use PCMRAW.EXE)

To do:
outliers routine to be revised.
Statistics routines need reworking.
Existing Datafile is backed up.

Purpose: 
Used for measurement of profiles using the
Water-SP-probes using the amplifier andthe PCM-DAS08-card, values are acquired
with n = 3000. Measurements are taken in 1
second intervals. The values are sorted using
Quicksort and are stacked "raw" as well as after
dismissing the highest and lowest 200 values as
'outliers'.


Requirements:
The Card must have an A/D-converter.
Amplifier and probes must be connected.
Analog Signal must be present.
CB.CFG must be in the directory specified by the
env-Variable "CBDIREC" or in present directory.
