7.44 PROTECTING FUNCTION CONFIGURATION PARAMETERS
(GROUP FF.1)
This group of parameters is used to define if the protecting function needs to be activated or not. Generally
no modification is required.
7.45 CORRECTION PARAMETERS (GROUP FF.2)
FF.2.25 AI1 Zero offset adjustment
Setting range: -0.500~0.500V
Factory default: 0.0
FF.2.26 Al1 gain correction
Setting range: 0.950~1.050
Factory default: 1.000
This group of parameters is sued to make fine adjustment to
AI1
zero point and
AI1
. The relationship before
and after adjustment:

FF.2.31 AO1 zero offset
correction
Setting range: -0.500~0.500V
Factory default: 0.0
FF.2.32 AO1 gain correction
Setting range: 0.950~1.050
Factory default: 1.000
FF.2.33 AO2zero offset
correction
Setting range: -0.500~0.500V
Factory default: 0.0
FF.2.34 AO2 gain correction
Setting range: 0.950~1.050

The correction principle for each analog input/output port is the same as
AI1
. The relationship curves with
zero offset adjustment and gain correction are respectively as below. Generally, users do not need to set
these parameters.
