9-3 Setting Wavelength
Make sure that the rotary encoder wavelength setting LED is lit.
When the LED is not lit, turn the rotary encoder change key to the wavelength side.
After making sure the wavelength setting LED is lit, set the wavelength by the rotary encoder.
The wavelength reading exactly follows the rotations of the encoder dial when the dial is grad-
ually turned, while the reading changes in unit of nm when the dial is turned fast. When the
wavelength display stops changing, it means that the wavelength is set in a range of 0 and 1nm.
The setting will complete in 170 msec.
TSL-210 wavelength setting includes slight hysterisis, and there is wavelength displace-
ment between the setting from short wavelength to long wavelength and the setting
from long wavelength to short wavelength, therefore, in setting wavelength, be sure to
set from short wavelength to long wavelength.
