Recovery Rate
Calibration /
Accuracy Check
The maximum recorded rate of change of the calculated oxygen value when the
test gas is removed and the measurement returns to the process value.
Notes
: A valid recovery rate cannot be calculated if:
a manual calibration / accuracy check is performed
either of the test valves are set to manual mode before the test is complete
a subsequent calibration or accuracy check is started before the test is
complete
the difference between the test gas value and process value is less than
10 % of the oxygen range
the maximum rate of recovery is not achieved within 3 minutes of removal of
the test gas
