The name CoMeter is an acronym for COMMUNICATING
METER. ProMeter stands for PROGRAMMABLE METER.
They can be connected, plug & play, into the terminal block
of the 695FI field indicator.
The CoMeter is capable to provide both reading and con-
figuration operations; the ProMeter is indicator only (HART
Communication is not for ProMeter). The LCD display has
three lines; the first one is used for 5 numeric characters,
up to 99999, plus a minus (-) sign on the left and a star (*)
sign, up on the right, to indicate HART communication is
in progress;
the second line is a 10 segments bargraph used to show
the output, from 0% to 100% in 10% steps;
CALIBRATION PROCEDURE . . .
the third line is used for seven alphanumeric characters to
display units or messages.
In addition to the display the plastic membrane has 4 push
buttons used for programming and for menus navigation.
And more precisely, they are:
top left position:
ESCAPE key
top right position: ENTER key
bottom left position: NEXT key
bottom right position: PREVIOUS key
Fig. 6 - CoMeter and ProMeter
The normal operating condition for CoMeter and ProMeter
is to display the analog output signal of the transmitter,
expressed in milliAmpere (this is the default setting), or in
percentage or in engineering unit, with all the units available
as for the HART Communication Protocol.
In addition to the indicator functionality, the CoMeter can
be used as a configuration tool, where both the CoMeter
itself and the transmitter can be configured. ProMeter is
only programmable.
In fact, two are the main menu : ConF METER" and "ConF
XMTR".
ACCESS TO CONFIGURATION
To enter these menù for both indicators, the keys PREV
and NEXT must be pressed simultaneously for 3 seconds,
then the user can switch between the XMTR and the ME-
TER configuration using the NEXT and the PREV key. The
ProMeter enters directly into the Manual Configuration, as
shown in the next page.
NOTE: when the Configuration action is finished,
remember to press the ESC key to return to display the
previous selected value.
ConF METER - METER CONFIGURATION
PASSWORD
The access to the configuration menus can be protected
by a 5 digits numeric password.
It is under the ConF METER menu that the password can
be defined and enabled.
See figure 7 for the access to the "ConF PASSWORD" menu.
Once you have entered the "ConF PASSWORD" menu the
cursor is blinking on the most significant digit.
Press ENTER, if you want to change the digits, initially set
to zero (0).
Use the NEXT and PREV key to increase or decrease the
value of the single digit, use the ENTER key to move the
cursor to the next digit, use the ESC key to move back to
the previous digit.
When the string "UPDATE?" appears on the display you can
use the ENTER key to accept the new password or the ESC
key to abort the password definition.
When all digits are set to zero, the password is disabled.
Next there are pictures to guide the configuration actions
for the CoMeter.
