Wavelength Calibration
Procedure
Wavelength Calibration Using the Internal Reference Light Source
IM 735302-01E
The instrument has a built-in reference light source for wavelength calibration, and
infrared light is always being output from the optical output connector. Never look
into the optical output connector. Infrared light entering the eyes can cause severe
injury and loss of vision.
1.
Turn the power to the instrument ON.
Turn ON the MAIN POWER switch and press the POWER switch.
For instructions on turning the power ON and OFF, see section 3.4.
2.
Use a 9.5/125 µm SM optical fiber to connect the instrument's optical input
connector with the optical output connector.
3.
Press the SYSTEM key. The soft key menu is displayed.
4.
Press the WL CALIBRATION soft key.
5.
Press the BUILT-IN SOURCE soft key.
6.
Press the EXECUTE soft key. Wavelength calibration is executed. The previous
screen is displayed again after the calibration process ends.
7.
Press the CANCEL soft key during wavelength calibration to cancel the
wavelength calibration process.
Note
•
Always perform wavelength calibration after turning ON the power to the instrument and
allowing the warm-up to finish.
•
If you are using this instrument for the first time or using it after it has been severely shaken
while being moved, you must perform the alignment adjustment procedure after warm-up
ends.
•
If the wavelength error of the instrument is outside of ±5 nm, you cannot perform wavelength
calibration with the internal reference light source.
(Readjustment required. Contact your nearest Yokogawa representative.)
