2.3.5 Modifying Parameters (Settings)
Particle Sizes:
This three-channel particle counter allows the user to select three predefined
channel sizes from 0.3 μm, 0.5 μm, 1.0 μm, 2.0 μm, 2.5 μm, 5.0 μm, 10.0 μm, and
15.0 μm. Channel 1 will always be the smallest size, followed by channel 2 and 3. If
the FS209E/ISO alarm is enabled, the channels will be locked to 0.3 μm, 0.5 μm,
and 5.0 μm and cannot be changed until the FS209E/ISO alarm has been disabled.
Sample Parameters:
The sample parameters screen will allow the user to modify the following parameters
over the following ranges:
• Start Delay: 00:00 to 59:59
• Sample Interval: 00:00 to 59:59
• Sample Duration: 00:00 to 59:59
• Number of Samples: 0 to 500
• Material: PSL, Sand, Lead, Carbon, or User Defined
• Count Mode: Cumulative, Differential, Counts per Liter, Counts per Cubic
Foot, Counts per Cubic Meter, Mass Concentration (option) or Particulate
Matter (option)
• Location: A0 to Z9
Start Delay
The start delay is defined as the time before ANY measurements are taken. This
feature is a timer for a sampling process to occur at a later time. The sample
