13.4 Calibration of sensors
To ensure correct calibration it is necessary to do this at two points:
➢
the first compared to a reference ZERO gas (80% or 21% O
2
according to the sensor)
➢
the second compared to a reference SPAN gas (100% O
2
)
•
•
•
Connect the bottle with reference gas (ZERO or SPAN) to the 3-way valve and turn the valve handle on the reference gas.
Ensure that the flow is about 100 ml/min.
Wait until the value is stabilized.
For the reference ZERO gas bottle, operating the screw of the "ZERO" of the sensor, repeat the O
2
value of the PROCOM 2 to the
reference ZERO gas.
For the reference gas bottle SPAN, operating the screw of the "Span" of the sensor, repeat the O
2
value of the PROCOM 2 to the
reference SPAN gas.
Restart the ZERO gas and then the SPAN gas in order to confirm the calibration.
At the end, push the '80%' key and the '100%' key on the PROCOM 2 in order to confirm the periodicity of the calibration of the two
standards.
