4.6 Making a Draft / Pressure Measurement
The difference in pressure (ΔP) between two areas can be measured by
using the analyzer’s two pressure ports and the Pressure screen. By using
the -ΔP port as the reference, the pressure applied to the +ΔP port will be
displayed on the Pressure screen as the differential pressure between the
two ports. Perform a draft / pressure measurement as follows:
1. Power on the analyzer and allow it to complete its warm-up cycle.
2. Press the
MENU (F2)
button to access the Main Menu.
3. Use the ▲▼ buttons to select Pressure. Press
ENTER
to display the
Pressure screen.
