ADDENDUM FOR COMETER - ANALOG LCD INDICATOR WITH HART
PROGRAMMING CAPABILITY AND PROMETER - PROGRAMMABLE INDICATOR
The name CoMeter is an acronym for COMMUNICATING
METER. The name ProMeter stands for PROGRAMMABLE
METER.
It can be connected, plug & play, into the standard terminal
block of the 2600T Series Pressure Transmitter.
It is capable to provide both reading and configuration
operations, when used in connection with the analog-only
version, the ProMeter is only indicator.
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;

The normal operating condition for the CoMeter 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.
In the CoMeter, in fact, two are the main menu : "ConF
METER" and "ConF XMTR".
ACCESS TO CONFIGURATION
To enter these menù, in both configurators, the keys PREV and
NEXT must be pressed simultaneously for 3 seconds, then the
user can switch between the XMTR and the METER
configuration using the NEXT and the PREV key. In the
ProMeter entry is directly in 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.
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:

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 5 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.
