PC6000 Software Operations Manual

The user must now write compensation files which contain the above data points and
which will be accessed automatically by the PC6000 software. If the "C:\PC6000" prompt is
displayed, the files will be located in the same subdirectory as the SRUN7.DAT data file. A
compensation file for each parameter (DO and pH, in this example) must be written. Since the
overall filename is SRUN7.DAT, the DO compensation file will be called SRUN7DO.CMP
and the pH compensation file will be called SRUN7PH.CMP. Note that for accurate record
keeping, the compensation file name should somehow be related to the name of the overall
study. For example, it will become extremely confusing if all dissolved oxygen compensation
files are named "DO.CMP" as shown in the brief example in the manual.

4- To compose the DO compensation file, type the following at the "C:\PC6000" prompt

The screen will display "1 File Copied" if all is correct and the file SRUN7DO.CMP will now
be in the "PC6000" subdirectory of the C drive. Note that the data must be entered in exactly the
above format:

(1)

The time must contain a designation for seconds even if the user does not
know this value exactly; an entry of XX:XX:00 is suggested for all time inputs

(2)

There must be a space between the date, time, and parameter value entries.

5- To compose the pH compensation file, type the following at the "C:\PC6000" prompt:

The screen will display "1 File Copied" if all is correct and the file SRUN7PH.CMP will now
be in the "PC6000" subdirectory of the C drive.

After writing the DO and pH compensation files to the C:\PC6000 directory, type
"PC6000" at the "C:\PC6000" prompt to re-enter the PC6000 software package. Just as would
be done for no compensation, prepare the plot and report output format desired by manipulation
of the "Parameters", the "Control Information", and the "Scaling Information".

After the format is finalized, re-enter the "Parameters" section of the software. Place
