Selected Folder / Memory Location - location where
data will be saved.
DierentialPressure- measured dierence between
Pressure High Side (+∆P) and Pressure Low Side (-∆P).
Zero Button - press to zero (calibrate) pressure
reading to ambient pressure.
Save - save pressure data to the selected folder /
memory location.
Print - print pressure data to IrDA / Bluetooth
®
printer(s).
IMPORTANT: Printing via Bluetooth
®
is diabled when the analyzer is connected to
the PCA
®
400 App. If you wish to print, disconnect from the mobile app or enable

4. Insert Probe Tube into Measurement Area
After identifying the ue / exhaust stack, select a safe and convenient location from which
to take measurements.
f To measure draft: insert the probe tube into the ue / exhaust stack / measurement
area and observe the reading on the Pressure screen.
f To measure dierential pressure: connect sampling hoses to the +∆P and -∆P ports
and place the ends of the hoses into the measurement areas being compared. The
dierential pressure between the two areas will be displayed on the Pressure screen.
The dierential pressure reading will be positive if the pressure at the +∆P is higher than
that read at the -∆P and negative if it is lower than that read at the -∆P.
