Be sure to save the entry and compare the values once more. Repeat as
necessary to within 2 mmHg.
The Calibrate Vacuum/Flow Zero screen calibrates the vacuum/flow sensor
at zero value. This is done automatically with every filter tape change.
However, if for any reason this needs to be done, proceed to the following
screen below to execute a zeroing filter tape change.

The Calibrate Vacuum Pressure Span screen allows the user to view and set
the vacuum sensor calibration span point.
To calibrate the vacuum sensor, zero a digital manometer (capable of
measuring up to 100 mmHg) and attach to the +ΔPA port on the rear
panel. Then push the toggle switch on the right inward to open (see Figure
4–1). The manometer reading can now be used to calibrate the vacuum
sensor.
