8.8 Beginning a Sample Job
To initiate a run and manage the data generated by the PQ100, a file must be opened at
the beginning of a job to store site and other background data along with "Initial Filter
Weight". Initial weight is used when the job is complete to determine delta weight (final
weight, minus initial weight) and when combined with sample time is used to compute
concentration.
From the PQ Main Menu press "b" to Begin a Job File for a Run. The resulting screen
requires that you adopt a Job File naming convention.
a. Default method By pressing enter at the prompt, a unique name will be given to the
file based on today=s date and run number.
b. Custom method Type in anything you wish.
Once a file name has been entered, a number of other fields are presented such as Site
Name, Station Code, Job Code, Operator, Filter Number, and Initial Filter Weight. You
may press enter for each field which will leave it blank. The job file editor provides the
means to enter the data later if you wish, however, it is recommended that the fields be
filled when beginning the job to avoid confusion and to maintain chain of custody.
8.9 Downloading
When a sample job has been completed, the data pertaining to the run is stored in the
PQ100 until it is reset by the user. Prior to resetting the PQ100 for its next run, the data
should be downloaded using the PQ software to provide information such as run time,
total sample accumulated, cause of the shutdown etc. All of this data is important in
determining the particulate concentration and conditions during the prior run.
From the PQ Main Menu press "I" to import data from the PQ100. The resulting screen
will prompt you for a file to append the download to. This should be the file that was
begun in the previous step to insure file integrity. If you do not remember the name of the
file, go back to the MAIN MENU and select "d" to view a directory of current files. If
you try to select a file that was already appended with a download, the system will let you
know. When the proper file has been selected you are ready to download.
THE CQ2 COMMUNICATION CABLE SHOULD NOW BE ATTACHED TO THE
PQ100 AND TO THE PC "COM1" or "COM2" PORT. THE PQ100 MUST BE
POWERED ON AND AT THE MAIN IDLE DISPLAY FOR THE DOWNLOAD TO
WORK!
