Count Alarms Screen
Configure count alarm limits for two particle sizes. To disable count alarms, select OFF
in the field next to the COUNT ALARM header. The alarm for a specific particle size can
be disabled by setting the alarm value to zero. The alarm is active when the count is
equal to or greater than the alarm limit. The maximum alarm limit value is 9,999,999.
Figure 19 shows the Count Alarm Screen.
Alarm values do not change with the count units setting (TC, /L, CF, M3). In other
words, a value of 1,000 will alarm at 1,000 counts or 1,000 particles per liter or 1,000
particles per cubic foot depending on the count unit setting.
