With these parameters, the
scaling of the input current
signal (I
in
) range can be set
between 0—20 mA.
Minimum setting:
Set the I
in
signal to its minimum
level, select parameter 2 ..... 12,
press the Enter button.
Maximum setting:
Set the I
in
signal to its maximun
level, select parameter 2 ..... 13,
press the Enter button.
