• DATA DISPLAY: This indicates whether the counts are being
displayed in Differential (Diff) mode or in Cumulative (Cuml)
mode and, if the counts are normalized to ft
3
or m
3
.
• MODE: Displays the current mode selected; possible modes are
AUTO, MANUAL, CONC (Concentration) and BEEP. The
exception to this is when a recipe is being run in which case the
MODE area will display number of cycles run versus the total to be
run (x / 6).
• CYCLES: Indicates the number of times the count will be taken at
a given location in Auto mode. "1/ 3" indicates the count is the first
of three samples to be recorded at this location. The maximum
number of cycles is 999. When set to 0, the unit will run in Auto
mode continuously until the STOP button is pressed.
• SAMPLE: The Sample Time (hh:mm:ss) is the duration of one
counting cycle. The Sample Time will count down on the MAIN
screen when the instrument is in AUTO or Manual mode so the user
can see how much time is remaining in the sample period. In
Concentration mode, the Sample Time will count up to 6 seconds
per cycle.
Note:
If Hold time is
greater than 1 minute, the
pump will stop during that
time. At the end of the hold
time, the pump will restart.
• HOLD: Displays the hold time in between cycles. The maximum
hold time is 23 hours, 59 minutes, 59 seconds.
• RECS: This displays the current number of records stored in the
instrument and the total number of records that can be stored. The
data buffer is a circular buffer. The instrument can store up to 3000
records. An asterisk (*) will appear in front of counts when the
buffer wraps.
