LCD Display
The LCD is primarily for displaying information from the meter’s registers for meter
readers. It is also useful during installation, configuration, and diagnosing problems. It
has 8 seven-segment digits to display values and up to 7 seven-segment digits to display
description. It has arrows to indicate import and export for active and reactive energies,
indicators for phase voltage, indicators for display sets A and B, battery indicator,
connection type indicator for connection through local or remote port and units and
multipliers.
LCD Variations
There are several variations of the LCD display for different meters, mostly varying in
the number of enunciators and id digits. They all operate in a very similar manner
though, presenting a series of pages of information. Each page can display a single
register’s contents. On the display the smaller digits at the left are the label for the
display, and the larger digits to the right are the value.
The Mk10 and Mk10E display (Figure 7-1) has 7 label digits, and 12 enunciators.
