Function Description
Figure A
The sign of measured quant-
ity and output quantity re-
mains the same. The output
quantity is proportional to the
measured quantity.
Input and output scaling capability
Working of the analogue outputs (y) versus input variables (x)
Figure B
The sign of measured quant-
ity and output quantity
changes simultaneously. The
output quantity is proportion-
al to the measured quantity.
Figure C
The sign of measured quant-
ity and output quantity re-
mains the same. On the
range X0...X1, the output
quantity is zero. The range
X1...X2 is delineated on the
entire output range Y0 =
Y1...Y2 and thus presented in
strongly expanded form.
Figure F
The sign of the measured
quantity remains the same,
that of the output quantity
changes as the measured
quantity leaves range X0...X1
and passes to range X1...X2
and vice versa.
Figure E
The sign of the measured
quantity changes but that of
the output quantity remains
the same. The output quant-
ity steadily increases from
value X1 to value X2 of the
measured quantity.
Figure D
The sign of measured quant-
ity and output quantity re-
mains the same. With the
measured quantity being
zero, the output quantity
already has the value
Y1 = 0.2 Y2.
Live zero output.
