3.1.1 Setting the Wavelength
You can set the correction wavelength for the sensor head to match the used
wavelength. The sensor element has wavelength sensitivity characteristics. To obtain
accurate measurements, the instrument is set to a wavelength that matches the
wavelength of the measured light.
Choosing a Typical Wavelength
1. Perform the operation from the initial screen in normal measurement mode
(Figure 3-1).
2. Press
the
λ
key. The wavelength setting screen appears.
。

3. Each time you press the
UP
key, the displayed wavelength cycles through
the following options: “
405
”, “
660
”, “
785
”, “
Prev Val
”, “
Usr
”, “
405
”, and so on.
Pressing the
DOWN
key cycles in the reverse order.
(Note:
Previous value
refers to the wavelength most recently set.)
4. After selecting a wavelength, press the
ENTER
key. The typical wavelength
setting is finalized.
Setting to an Arbitrary Wavelength. (Can Be Set in Units of 1 nm).
5. After setting the wavelength display to “
USr
”, press the
ENTER
key.
The detail wavelength setting screen appears.

6. Press
the
UP
or
DOWN
key. Change the wavelength in units of 1 nm.
The available setting range is 400 to 850 nm.
7. Press
the
ENTER
key. The detail wavelength settings are finalized.
