Figure 4.3. The Status Window displaying Zero calibration in
Progress.
The Zero/O
2
Span is started controlled by the BZ6012 going through
the following steps:
i)
The pump is turned OFF and all solenoid valves are deactivated.
ii)
After a settling delay, the ambient pressure (Atm Press) is
measured and stored.
iii)
The pump is turned ON.
iv)
After a settling delay, the sample cell pressure (Abs Press) is
measured and stored.
v)
The absolute pressure limit is checked (Abs Press – Atm Press)
Pressure Limit.
If this test fails, the Pump Out Flow Check is shown in the Status
) and the zero calibration procedure is aborted:
