Serial Readout Menu
An actual value proportional to the input frequency can be read out via serial link, accessing the
serial readout register (code :8 ) As a Basic Value this register uses the scaling set for the
analogue output, i.e. a range from 0 to 10 000 units corresponding to 0 - 100,00% of the full
scale output (see "Analogue Menu"). This readout can still be rescaled to user-friendly
engineering units, using the following parameters:

The definition of the "Basic Value" occurs in the "Analogue Menu" and is also
available for the DZ277 units without analogue output
the ratio Multiplier / Divider must never be greater than 15 000
Setting "Divider" to zero will skip the rescaling procedure, resulting in a shorter
response time with all functions of the unit
More details about serial communication can be found in the appendix.
