The Global Parameters screen appears.
2. Use the up and down arrow keys to enter the Operator ID. This field
has a limit of 12 alphanumeric characters.
3. Enter the number of runs (1-99), then push Enter. This is the number
of analyses for a specific testing cycle and the value used to
calculate run averages.
4. Enter the Delete Time — 00 H, 00 M, 00 S and 02 H, 59 M, 59 S.
Delete Time is a period of time to select whether to keep or delete
the run data. The default value is 00 H, 00 M, 015 S. Delete Time is
active only if the number of runs is set to greater than 1.
The Delete Time clock operates at the completion of each run. The
next run cannot start until the Delete Time cycle is complete or the
KEEP RUN or DELET RUN key is pushed.
5. Enter the Delay Time between 00 H, 00 M, 00 S and 99 H, 59 M,
59 S. This is the time between the end of a run and the start of the
next. The default Delay Time is 00 H, 00 M, 15 S.
The Delay Time clock starts after the last Delete Time period of a run
series is complete.
6. Select English or Metrick for the units of measure for all displays,
then push Enter.
7. Enter the Quick Adjust Rate between 00 H, 00 M and 48 HH 59 MM.
The counter automatically does an internal calibration cycle (or quick
adjust) at this interval. A rate of 00 H, 30 M is recommended. To
disable the feature, enter 00 H, 00M.
If a quick adjust cycle is set to start while a sample is being run, the
quick adjust cycle does not start until after the sample run is
complete. If a host command is received before a quick adjust cycle
is complete, the command is held until the end of the quick adjust
cycle.
8. Push Exit to save the settings and go back to the Parameter Setup
menu.
209E setup parameters
Use this function to set up the counter for a FED-STD-209E aerosol
analysis. The first screen contains the variables, and the second screen
contains the bin size thresholds.
Push ENTER to confirm a menu selection.
1. In the Parameter setup functions menu, push 209E SETUP.
The display shows the FED-STD-209E Parameters screen.
2. Enter the setup parameters for the first screen.
Option Description
Volume units English (particles per cubic foot) or Metric (particles
per cubic meter)
Cleanliness class The number of particles greater than
0.5 micrometers in diameter per given volume.
Locations The number of sample points available—2 to 992.
Min samples/Location The number of samples taken at each location.
Range: 1 to 99.
Sample time The length of each sample interval in seconds.
Last display channel The number of the highest channel that appears in
the displays. Used to remove the display of higher
channels when the channel data is not necessary.
Range: 1 to 8.
Print results YES or NO
• YES--print the results of the analysis after
samples have been taken at all designated
locations.
• NO-- do not print the results. Print functions for
individual samples or averages are set in the
Printer Functions menu.
Sample volume This read only value is the sample volume selected
by the user. The value is calculated from the rate of
sample flow through the sensor and is shown in the
units specified in the Volume Units field.
3. Push NEXT PAGE to view the second screen.
4. Enter a value for the threshold setting for each of the 8 channels
between 0.01 and 9999.00 µm.
The lowest threshold value is assigned to the lowest designated
channel, and each succeeding channel has a larger value. If this
