The current output signal characteristic can
be matched to the requirements of the
downstream signal processing, display or
recording equipment.
The allocation of the measured value to the
current output signal depends on the internal
measuring ranges of the instrument and the
characteristic curve you select.
Choose between the following characteristics:
A) linear
B) bilinear
C) logarithmic
D) Table (freely programmable
current output characteristics
A) Linear current output signal characteristic
