Count MODEs
Count modes available are Auto, Manual, Beep and Concentration.
Use of a recipe, however, overrides the display of these modes.
• AUTO - When the instrument is in Automatic Mode and the
START button is pressed, the instrument will start counting
particles automatically according to the Sample Time, Hold Time
and the number of Cycles that are configured.
If Cycles are set to 0, the instrument will continue indefinitely in
Auto Mode until the STOP button is pressed.
• MANU (Manual Mode) - When the instrument is in Manual
Mode, it will start counting when START is pressed and stop at the
end of one programmed Sample Time.
Note:
BEEP mode only
works with CUMULATIVE
data and for Sample Times
equal to or greater than 6
seconds.
• BEEP - In this mode, the instrument is pre-configured to beep
according to the alarm threshold set in the Alarm configuration and
the instrument’s sample time when the instrument is set to collect
cumulative data. Counting starts after the START button is pressed
and the pump flow rate is stable. It will continue until the STOP
button is pressed or the number of configured cycles is reached.
If no channel is set for alarming when BEEP mode is selected, the
instrument will automatically use the smallest channel size and its
alarm threshold setting to alarm.
If alarming is enabled on more than one channel when the
instrument is in BEEP mode, it will beep if the alarm threshold is
exceeded on any of the channels enabled for alarming.
