Operations Performed When the Power Is Turned On
If initialization finishes successfully, a message appears prompting you to execute
wavelength calibration and alignment adjustment.
The contents of the message are as follows.
For this instrument to meet its specification, a Wavelength Calibration and an
Optical Alignment Adjustment must be performed. Please perform these operations
according to the guidelines below.
Alignment Adjustment
Always perform alignment adjustment the first time you use the instrument, if
the instrument was vibrated when being moved, or if the temperature in the
operating environment has changed. Perform the alignment adjustment after a
one-hour warm-up.
Wavelength Calibration
Be sure to perform a wavelength calibration using an external light source
before starting measurement (a warm-up of one hour is also required prior to
measurement). Unless the Wavelength Calibration is carried out, the wavelength
accuracy of the instrument cannot be guaranteed.
When the Power-on Operation Does Not Finish Normally
Turn off the power switch, and check that :
• The instrument is installed properly. See section 3.1, "installing the instrument."
• The power cord is connected properly. See the previous page.
If the instrument still does not work properly, contact your nearest YOKOGAWA dealer
for repairs.
If an error occurs in the memory or some other part of the instrument during
initialization, the AQ6370C will stop running with "STEP @ / 9" showing on the screen
(where @ is a number between I and 9).
If this occurs, repairs are necessary. Contact your nearest YOKOGAWA dealer
immediately.
Note
• See section 3.5 for details on the alignment adjustment operation, and 3.6 for wavelength
calibration.
• The instrument “remembers” measurement conditions, selected soft keys, waveforms being
displayed, and other information. When the power is turned ON, the state of the instrument
prior to the last shut down is restored. When the power is turned ON for the first time, the
instrument starts up in the factory default state.
