3.4.7 Conc Chart
This screen provides a chart of the last 24 hourly (Conc HR) concentration measurements.
3.5 Test Menu
The Test Menu provides a means of testing and calibrating individual sensor inputs and
calculations. Because these settings directly impact flow and concentration values, most of these
tests are password protected.

3.5.1 Leak Test
This screen provides the options and indications
needed to perform a leak test of the sampling
system. The grey pump control button in the
lower left corner will read PUMP ON which
indicates that pressing it will turn on the pump.
Similarly, when the pump is running, this button
will display PUMP OFF.
Figure 3-13 The Leak Test Screen
The grey NOZZLE control button in the lower right corner will always be labeled as NOZZLE when
this test screen is first entered. Pressing it will cause the vane to change state from up to down or
down to up. The button will now display what will happen if it is pressed again, just like the pump
control button. This means that it will read NOZZLE UP if the vane is in the down position or
NOZZLE DOWN if it is in the up position.
The flow and lower pressure sensor indications are provided for reference when performing the leak
test. See section 5.2 for detailed instructions on performing a leak test.
