10.2.5 Operating mode
By selecting the operating mode (channel E) you define the calculation method according to which the
measured variable is to be acquired and the output signal is to be represented.
By selecting the operating mode you define
- the assignment of the primary HART
- the measured value in "channel 4".
The following operating modes are available:
- density in kg/m³ (for equation 1, 2 and 3, see section 11)
(there is a choice between operating density or reference density, depending on the
α value)
- concentration in % (for equation 1, 2, 4 and 5, see section
The analog output signal (4 to 20 mA) can be freely assigned to the desired measuring range (lower
range value: channel 5, upper range value: channel 6) within the meter range.
The minimum measuring range span should not be below a density range of 5 kg/m³.
