7.8 Customizable linearisation of analogue input
Selecting
16 steps
on parameter 17
V/I custom
and connecting a linear sensor
it is possible to customize the linear input for a max. of 16 steps. On parameters
xx-Input value
it is necessary to enter the value of the input to which the value
selected on the corresponding parameter
xx-Custom value
will be related.
EExample: sensor 0-5V.
01-Input value=> 0.000V 01-Custom value=>0mBar
02-Input value => 2.000V 02-Custom value=>100mBar
03-Input value => 4.000V 03-Custom value=>500mBar
04-Input value => 5.000V 04-Custom value.=>1000mBar
At each value in Volt (input) a value in mBar (customized) is related: if the sensor
supplies 2V the device visualizes 100mBar, if it supplies 4V the device visualizes
500mBar. For intermediate tension values the value in mBar is calculated
linearly between the entered values containing it: 1V = 50mBar, 3V=300mBar
and 4,5V=750mBar.
