Initial Leak Check and Flow Check
Perform a leak check and flow check/calibration as described in Section 5. Become comfortable with these processes,
as they will be performed often.
3.8
Starting a Measurement Cycle
When the preceding steps of Section 3 have been completed, exit out to the main top level menu. The “Status” line
should display “ON” (no errors). If so, the unit will start at the top (beginning) of the next hour, and will continuously
operate until it is commanded to stop.
The unit will stop if the operator sets the Operation Mode to OFF or enters any of the SETUP or TEST menus. The
APDA-371 will also stop itself if a non-correctable error is encountered, such as broken filter tape or failed air flow.
3.9
The Flow Statistics Screen
In the main APDA-371 menu screen a small arrow has been added to the bottom right corner. When the DOWN
ARROW button is pressed the APDA will display the FLOW STATISTICS screen as shown below. This screen displays
the flow, temperature and pressure statistics for the current measurement cycle. Pressing the ARROW DOWN key
while in this screen will further scroll down to the remaining parameters below the viewable area of the display. This
screen will not interrupt the sample. This function is only available with revision 3.2 firmware or later.
