Calibration
The Calibration menu enables a two-point
calibration process for the F-940 including Zero
Calibration and Span Calibration. The set zero
process will require known standard gas of
100% Nitrogen (N
2
) gas to set a zero baseline.
Next the user will be prompted to connect a
known standard gas to set the span for your
sensors. We suggest the following:
C
2
H
4
Set Span: 5 ppm C
2
H
4
standard gas
CO
2
Set Span: 95% CO
2
standard gas
O
2
Set Span: 50% O
2
standard gas
Each sensor will require its own standard gas
for calibration. After the set span is complete it
is best practice to verify your calibrations were
successful by reading the standard gas to
ensure accuracy.
