9-2 How to Use Rotary Encoder
This product does not come equipped with a numeric key to input numeric values. A rotary
encoder is used to set wavelength, and to set optical output power (in APC mode only), to
ne tune, to calibrate wavelength, to set GP-IB address, and to set the minimum increment/
decrement resolution of the encoder. Turning the encoder to the left decreases numeric value,
while turning it to the right increases numeric value. The tunable step of the encoder changes
four steps according to rotational speed.
