3.3.10 Software Write Protection
The transmitter configured data is saved by using a
write protection function. The write protection status
is set to “Yes” when 8 alphanumeric characters are
entered in the
New password
field and transferred
to the transmitter.
When write protection is set to ”Yes,” the transmitter
does not accept parameter changes. When the
same eight alphanumeric string entered in the
New
password
field is also entered in the
Enable wrt
10min
field and transferred to the transmitter, it
will be possible to change transmitter parameters
during a 10 minute period.
To change the transmitter from the write protection
”Yes” status back to write protection ”No” status,
use
Enable wrt 10min
to first release the write
protection function and then enter eight spaces in
the
New password
field.

3.3.11 Signal Characterizer
This function is used to compensate the output for
non-linear applications. The characterized values
are applied to the analog 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 transmitter 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”.
