generator and its subcomponents act as peripheral devices operated

by the CPU via the motherboard. Sensors, such as the UV lamp thermistor send analog
data to the motherboard, where it is digitized. Digital data is sent by the motherboard to
the calibrator‟s CPU and where required stored in either flash memory or on the CPU‟s
Disk-on-Module. Commands from the CPU are sent to the motherboard and forwarded
to the various devices via the calibrators I
