on using the key.
5310 The Zero Loss of a
certain Polarization
State of a specified
channel is missing
The reference for the
channel has not been
taken.
Perform a zero loss
(reference) measurement.
5330 Dark Voltage
Measurement error.
Too much light in the
specified detector.
The detector is not
capped.
Cap the detector to ensure
that all light to the detector is
