Mode Description Sample Unit<br />
Concentration This mode is useful for taking a quick snapshot of<br />
airborne particulate samples, especially in areas where<br />
particulate levels are unknown and may exceed the<br />
operating levels of the counter. The <strong>HHPC</strong>-2 estimates<br />
count per cubic foot or liter depending on the volume<br />
selected. The unit updates the results by calculating<br />
completed sample counts and volume compared to the<br />
balance of volume remaining.<br />
Rate Counting is continuous. The displayed counts are a ten<br />
sample sliding average.<br />
Totalize The number of counts are displayed as they accumulate<br />
until the end of the sample. When the sample is<br />
completed, the record is stored and the value is displayed<br />
on the screen until the next sample is started.<br />
