If Lambda Zero is recommended (Accuracy Class is not ACC1) the 10
of the "questionable condition register" is set (See the Agilent 8163A/B
Lightwave Multimeter, Agilent 8164A/B Lightwave Measurement System,
Agilent 8166A/B Lightwave Multichannel System Programming Guide).
This is done in both Auto Cal On and Off.
When Auto Cal is on, during sweeps, there is no interruption to the
measurement due to settling. Also no settling will occur during operation
at a fixed wavelength when at least one output is switched on. By
periodically checking the "questionable condition register" bit 10 you can
detect when Lambda Zero is recommended.
