• View installer signature
This signature will only be available to view
only (not for plotting the graph) if the user
has captured the installation signature using
the keypad/lCD. The installation signature
is basically generated by the person who
is installing the whole integrated valve
package to the process plant. The purpose
of generating this signature is to make sure
the whole package was tested when it was
installed at the plant but before the plant
starts running the process. This signature
can only be generated using the keypad/lCD
and not from the DD/ DTM. however the data
can be viewed from the DD/DTM. none of the
data from this signature is used to compare
against other data to generate any alert or
alarm.

• View baseline signature
This menu will only be available if the user
has captured the baseline signature on the
device. as explained before, this signature
acts as a baseline reference to compare
all future maintenance signature data
against and generate degradation alerts.
This signature is usually captured during
commissioning of the plant. Once captured,
the signature data can be viewed under this
menu. Due to the limited are on the lCD, only
numeric data is displayed. however using
the DD/DTM, the signature can be plotted for
graphical representation.
Refer to Figure 82
From the View Sign Menu, scroll down to
“View Base” to view the Baseline Signature
stored on the device, then press SElECT.
note if this Signature does not exist on the
device, the lCD will show “not available”
