Figure 5-2 - Sample Setup Screen
5.2.1 Location ID
The Location ID is used to assign a unique name to a location or area. This important field is
included in sample data records (display and csv output). Use the dial to scroll through a list
of custom location IDs. To edit the list, see toolbox location ID in section 5.4.4.
5.2.2 Sample Time
The Sample Time is the length of time the unit will sample for. The sample time is user
selectable from 1 minute, 2 minutes, 5 minutes, 10 minutes, 15 minutes, 30 minutes, or 60
minutes.
5.2.3 Units
This setup feature allows the user to select the concentration to be displayed in ug/m3 or
mg/m3.
5.2.4 Zero Period
The Zero Period allows the operator to select the Auto Zero / Self-Test time interval. This is
user selectable intervals of 1-Hr, 2-Hr, 12-Hr, 24-Hr.
When the unit is started it first enters a Purge / Zero cycle where the purge pump is turned
on to purge the dirty particles from the engine then it does a zero calibration. A span check
then occurs after the zero calibration if it is enabled. This sequence is repeated at the
interval selected for the Zero Period.
