When you lose the password that has been registered, it
is possible to release the Write Protect mode by
using the general use password: “YOKOGAWA.”
When the password is used, the status shown in the
parameter of Software seal is changed from “KEEP”
to “BREAK.” The status returns to “KEEP” by
entering a newly set password at Enable wrt 10min.
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.
