Operations Performed When the power is Turned On
When the initialization finishes successfully, the following measurement screen appears.
For this instrument to meet its specifications, a Wavelength Calibration and an Optical Alignment
Adjustment must be performed. Please perform 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.
For details on alignment adjustment, see section 3.4.
Wavelength Calibration
Perform wavelength calibration 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 a memory error or other errors occur during initialization, initialization is cancelled at the step in
which the error occurs (STEP @/9, where @ is a number from 1 to 9). Then, the screen changes to
the measurement screen, and a warning message is displayed.
If this occurs, repairs are necessary. Contact your nearest YOKOGAWA dealer immediately.
