3.5.2
Calling the Preset Wavelength
The four preset wavelengths in the wavelength setting can be called and set.
An example, in which a preset wavelength of 405 nm in No.1 is called, is shown below. See Figure 3-6.
The preset wavelength from No.0 to No.3 is called sequentially by pressing the
[
RECALL]
key.
If the wavelength, which is a value outside the wavelength range of the current connected sensor, is called,
“n FAIL” (n is the wavelength number) is displayed and the wavelength is not set.

If the wavelength, which is a value outside the wavelength range of the current connected
sensor, is called, “n FAIL” (n is the wavelength number) is displayed and the wavelength is
not set.
•
If the wavelength, which is a value inside the wavelength range of the current connected
sensor, is called, “n SEt” (n is the wavelength number) is displayed, the wavelength is set,
and a new wavelength and wavelength sensitivity coefficient are displayed.
