28 Keysight 86120D and 86122C Multi-Wavelength Meters User’s Guide
1 Getting Started
Step 9. Set the System Standby Mode
If the multi-wavelength meter has been inactive for a specified period of
time, it will be switched into standby mode. When this happens, two things
will occur:
• The LCD display indicates the standby mode.
• If the instrument is in Continuous sweep mode, the motor movement,
and any related data collection, will be suspended.
Any subsequent activity, front-panel or remote, will reactivate the
instrument and return it to it’s previous state. Using this feature can help
extend the life of your instrument. To extend the life of the reference laser,
you should turn off the instrument during long periods of inactivity (e.g.
several hours or over night).
To configure standby mode
1 On the Setup menu, click Preferences.
2 Select a time-out period from the System Standby list. You can choose
15 min., 30 min., 1 hr., 4 hrs., or Never. Selecting Never disables this
feature.
The internal reference laser is always on to allow the instrument to
immediately make accurate measurements when it is reactivated.
