

• An arbitrarily set measurement wavelength is automatically saved in the measurement-wavelength memory.

• The measurement-wavelength memory holds up to 10 wavelengths (including preset wavelengths for each optical sensor).

• Each optical sensor has preset wavelengths. These preset wavelengths cannot be edited.

• Through the setting operation for the arbitrary measurement wavelength, the setting data is automatically saved in the mea surement-wavelength memory. When it is necessary to save a new measurement wavelength to the measurement-wave length memory when the memory already contains 10 wavelengths, the oldest data is deleted in order to make space for the new data.

• To reset the data in the measurement-wavelength memory, perform measurement-wavelength-memory reset. This will return the memory to its default state for each sensor.

 See Section 7.4.3 "Measurement-Wavelength Memory Reset" (52

3.4 Starting Measurement

3.3.2 Retrieving the Wavelength Setting from the Measurement-Wavelength Memory

Each time the λ key is pressed, the measurement wavelengths stored in the memory are retrieved individually in order.

To reset the data in the measurement-wavelength memory, perform measurement-wavelength-memory reset. This will return the memory to its default state for each sensor.

 See Section 7.4.3 "Measurement-Wavelength Memory Reset" (52 page)

3.4 Starting Measurement

• To ensure accurate measurements, make sure the detector window is free of dust, stains, and any damage.

• Confirm that the light to be measured fits completely within the detector window.

• If the optical power is too intense for the unit area, such as when a condensed beam on the focus plane is measured, the optical sensor may be saturated and the 3664 may not be able to conduct accurate measurement. This problem can be solved by changing the distance between the light source and the detector window of the optical sensor.

• The operation of the light source may become unstable due to the reflection of light from the detector window of the optical sensor. This problem can be solved by angling the detector window slightly to prevent the reflection from returning to the light source.

• If background light, sunlight, illumination light, or any other light than the light to be measured is overly intense, the 3664 may not be able to conduct accurate measurement. Take appropri ate light-shielding measures.
