Dynamic Range of the LASER
Dynamic range of the LASER is automatically tested at power up and whenever a test calibration occurs.
It is defined as the ratio of maximum laser power minus power monitor offset to minimum laser power
minus power monitor offset (Max power -- Offset)/ (Min power -- Offset). Power monitor offset is the power
monitor output value measured when the LASER is turned off. A laser dynamic range failure can be
caused by a bad power monitor offset value.
