COUNT MODE
The following modes are available: Auto, Manual, Beep and
Concentration.
• 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.
• CONC (Concentration Mode) - When the instrument is in
Concentration mode, it gives a calculated value of the concentration
of particles in a volume of air, measured and displayed on the
MAIN screen in either counts per cubic foot or per cubic meter.
Note:
The sample time
for Auto, Manual and Beep
modes count down and the
sample times for
Concentration mode count
up.
Counting starts when the START button is pressed and it will
continue until the STOP button is pressed. The sample time for
Concentration mode is six seconds. As the sample time on the
MAIN screen counts from one to six, the particle counts are
updated continuously.
