Measurement Cycle

The measurement cycle is controlled by the CMC. Depending on EEPROM settings, the multiplexer (MUX)

selects the following input signals in a defined sequence:

The cycle diagram in Figure 2.2 shows the basic structure of the measurement cycle. After power-on, the startup

routine is processed, which performs all required measurements to expedite acquiring an initial valid conditioned

sensor output. After the startup routine, the normal measurement cycle runs.
