SET POINTS SET POINTS SET POINTS SET POINTS SET POINTS
This instrument allows to use up to 4 set points: SP, SP2, SP3 and
SP4.
The set point selection is possible only by logic input.
Set point transfer
Set point transfer Set point transfer Set point transfer Set point transfer:
The transfer between one set point to another (or between two
different set point values) may be realized by a step transfer or by
a ramp with two different programmable rates of change (ramp
up and ramp down).
Slope value
