EMOVE
The signal of the transducer (±10 V or 0-20 mA) is converted in to the desired physical
measurement using a first order transfer function with the parameters of gain (��)
and offset (��) defined by the user:
�� = ���� + ��
where �� is the converted value and �� is the value read by the DC channel in Volts or
Amps.
The RMS value of the DC channels (transducers) is calculated every cycle.
To add a new DC channel select the DC C

Once the DC channel is created, it shows in the configuration interface menu. When
selecting the DC channel, a screen shows the characteristics of the DC channel
selected, as shown in Figure 26. It is possible to edit the frequency reference, gain,
offset and unit.
