MAINTENANCE 11
As the basic circuit of the PC-2300 is solid state, very little maintenance should
be required to keep it in top operating condition. The optical elements may collect
a film of dirt from the atmosphere, and the exposed optical elements may be
splashed with liquids. In both of these cases, the optical efficiency of the unit will
be reduced and calibration may change if a large reduction in optical efficiency
occurs. Such a change in calibration can be detected by a careful test with the
calibration standards.
If the laser diode fails, it is recommended that the unit be returned to the factory
or that the replacement be done (if necessary) by a factory trained service
technician. However, laser diodes have an incredibly long life and should not
need replacement for over 15 years.
