3.5.14 Signal Characterizer
This function is used to compensate the output
for non-linear applications. The characterized
values are applied to the 4-20 mA output. For
the measured pressure, a maximum of nine
coordinates can be specified between 0-100%.
Perform the coordinate settings while the S.C. at
S.C. menu parameter is Disabled.
To apply the settings to the output, set the
S.C.
parameter to Enabled.
Note that the EJX rejects the activation of the
function by AL. 60 with the following transmitter’s
status:
• When the specified coordinates of x and y are
not incremental as the input increases.
• When the output mode of the output signal is
set as Sq root; at the same time, the low cut
mode is set to Linear.
