Viewing Sample Data
Lasair II Particle Counter Operations Manual Page 6-5
NOTE: Pressing the Enter softkey normally enables the edit mode.
In this screen, however, pressing the Enter softkey enables a
navigation mode, that allows you to move left, right, up, and down
with the Arrow softkeys and other softkeys.
You cannot edit data on
the Lasair II particle counter .
Data Format —
The sample data in are described by columns, from left to right, as
follows:
•
Row Index: This number, which is always visible on the display, is useful for
keeping track of your place in the table. In addition, when printing samples the
number shown in the row index is the sample which will be printed. See
Figure 6-2, “Data Table Screen,” on page 6-4
• Date: the date the sample was completed in the format YYYY/MM/DD
• Time: the time the sample was completed in the format HH:MM:SS
• Location: the location name assigned to the sample data.
• Sample duration: the duration of the sample in the format HH:MM:SS
• Sample volume: the volume of air sampled expressed in the units selected on the
Data Display Screen. See Figure 6-3, “Data Table Display Setup Screen,” on
page 6-6.
• Particle Data: the particle count data is displayed in your choice of the
following ways:
➢
raw counts or normalized counts (particles per cubic foot or cubic meter)
➢
differential counts o r cumulative counts
NOTE: If Pharmaceutical mode is enabled, only 0.5
μ
and 5.0
μ
particles will be displayed. See Appendix G for more information.
• Analog data: Analog data is listed under the standard headings of T for
temperature, r/h for relative, and as many as four other user-selected headings.
Invalid samples will cause the entire row of data to be masked in gray. Analog
or particle alarms that occurred during the sample will cause the out-of-
tolerance number to be displayed in red.
