3.6 Wavelength Calibration
WARNING
The instrument has a built-in reference light source for wavelength calibration (when the built-
in light source specification is -L1), 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.

AVERTISSEMENT
Cet instrument dispose d’une source de lumière de référence (-L1 spécification) intégrée
pour l’étalonnage de la longueur d’onde. La lumière infrarouge est toujours émise depuis le
connecteur de sortie optique. Ne regardez jamais directement dans le connecteur de sortie
optique. La lumière infrarouge risquerait de gravement vous blesser ou de provoquer une
perte de vision.
Procedure
Wavelength Calibration Using the Internal Reference Light Source
(when the built-in light source specification is -L1)
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.

3.
Press the SYSTEM key. The SYSTEM menu is displayed.
4.
Tap Wavelength Calibration.
5.
Tap Built-in Source.
6.
Tap Execute. The wavelength is calibrated using the instrument’s built-in reference light
source. Wavelength calibration is executed for several minutes. The previous screen is
displayed again after the calibration process ends.
