c) SCALE Function
38
The output scaling on PCA-570 allows it to simulate the operation of a transmitter. In this case, the indication
of display scaling (#) simulate the input of transmitter (which can be changed by pressing on the number indicated in
the display and entering the desired value), and as an output signal we can have any of the signals generated by the
PCA-570 (for example, 4 to 20 mA).
The output SCALE function relates the output signal generated by the PCA-570 to what is shown in the
display, as in the example shown below.
The scaled (#) display indication can be changed to represent any unit such as: m/s, m3/s, %, etc.
