Note: During calibration, the fan inside the instrument is turned off to extend the life of
the desiccant. The fan will be turned on after returning to the AUTO mode or after
five minutes, which ever comes first. It is recommended that the measurement
chamber be kept covered during the calibration period and that the flow through
cuvette be replaced immediately after the calibration to prevent premature
contamination of the desiccant.
