GENERATOR ELECTRONIC OPERATION
Electronically the O
3
generator and its subcomponents act as peripheral devices operated by the CPU via the
motherboard. Sensor signals, such as the UV lamp thermistor are routed to the motherboard, where they are
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-chip. Commands from the CPU are sent to the motherboard and
forwarded to the various devices via the calibrator’s I
2
C bus.
