9.3 Correction input (CMGZ411)
The correction input (terminals d6 / d8 resp. 7 / 8) is needed to change the gain value defined. Under
parameter „Correction input“, it is possible to select a linear or a cosine correction. This parameter is
normally used if the wrap angle changes continuously.
Linear correction
The adjustment is made by entering a correction value
(1.000 without influence) at 0V input (parameter
„Linear correction at 0V“), and also at 10V input
(parameter „Linear correction at 10V“).
The measured value can be influenced to higher values
(>1.000) as well as to lower values(<1.000).
Cosine correction
The adjustment is made by choosing 3 positions within
the used correction range. Search parameter „gain
cosine at U1“ and press the
″↵″
key. Change the value
in the display in this position with the keys
″↑ ↓″
until
the effective value is displayed. Save the gain and
voltage values with
↵
key. The display shows now
„gain cosine at U2“.
Change now to the second position and press key
″↵″
.
Change the shown value in this position with the keys
″↑ ↓″
until the effective value is shown. Save again
with
↵
key. The display shows now „gain cosine at
U3“.
Change now to the third position and press key
″↵″
. Change the shown value in this position with the keys
″↑ ↓″
until the effective value is shown. Save again with
↵
key.
The correction voltage can be given also by a potentiometer.
