Fast Spectral Loss
Description
There are a number of reasons (described
below) that may require a lambda zeroing
operation. Such an operation takes several ten
seconds to complete. To minimize the impact
on running measurements, but keeping up the
wavelength accuracy, choose one of three
settings:
Always Ask (Default): Whenever a zeroing
operation is required, the user will be
prompted whether to perform the zeroing
operation or not. Once this situation occurs,
each subsequent measurement will cause
such prompt until either the user allows the
zeroing to be performed, or performs the
zeroing operation manually from the GUI or
changes the Lambda Zeroing Mode to either of
the other two settings.
Automatically: Whenever a zeroing operation
is required, it is performed automatically right
before the next measurement. This is the
recommended setting for optimum lambda
accuracy.
