Setting the Particle Counting Mode

The Particle Counting Mode choices are:
Concentration Mode
In Concentration Mode, the Particle Counter samples
a small volume of air and calculates what the value
would be for the volume setting on the Particle
Counter (liter, cubic foot, etc.). This mode is useful
for taking a quick glimpse of airborne particle
contamination levels. For example, Concentration
Mode might be used in areas where particulate levels
are unknown and may exceed the operating levels of
the Particle Counter. This mode should not be
substituted for full sampling.
Totalize Mode
In Totalize mode, the counts are seen as they
accumulate until the end of the sample. When the
sample is complete, the record is stored and the
value appears on the screen until the next sample is
started.
Audio Mode
In Audio mode, the Particle Counter beeps once
each time the alarm limit is exceeded, (see "Setting
the Alarm"). For example, if the limit is set to 10, the
counter beeps when the count first reaches 10 and
beeps again for each multiple of 10. In Audio Mode,
the display shows counts as in Totalize Mode.
