18 Meter Operation
Nameplate Message Identifiers
Various messages may be listed on the front of the meter in the nameplate area.
These messages describe certain states, functions, or actions that could be operating
in the meter. When any of the message states or functions are active in the meter,
the corresponding identifier F0, F1, or F2 is illuminated on the display. The meter
nameplate also includes an erasable strip that can be used to add more data to the
meter display.
Low Voltage Display
During a brownout condition, the meter display will show VOLT LO. This will
continue to be displayed until the meter is powered back up, or until it is completely
powered off. The meter display will also briefly show VOLT LO when the meter is
powered down normally, although the message will not persist in this case.
Display Value Items
The meter can display up to 30 numeric value items, which are chosen from the
available total and tariff energy measurements, as well as time, date, and prepay
energy credit remaining. The display scrolls through each item, with a
programmable scroll-time for each item of 6 to 15 seconds. The scroll-time is the time
that the value is shown on the display before scrolling to the next item. Each item
has a unique programmable 4-character ID code that is displayed along with the
value item.
You can use the meter push button to automatically advance to the next display
value item, before the scroll-time expires. Alternatively, you can disable automatic
scrolling, so that the push button must be used to advance the meter display to the
next item at all times. For more information on the meter push button, see “Push
Button Operation” on page 1.
The decimal point location for energy values is configurable, with an available range
of 1 to 8 digits to the left and 0 to 3 digits to the right of the decimal point. The
display of leading zeros can also be suppressed. The decimal point location and zero
suppression apply only to register values and prepay totals. Other display items,
such as date, time, firmware version, TOU calendar ID, and diagnostic codes are not
affected by the decimal point location and zero suppression settings.
When an actual value is larger than the number of digits configured to the left of the
decimal point, the most significant digits are not displayed. This allows the most
frequently changing digits to display. The actual stored values are not affected.
The following are the choices of items that are available to be shown on the meter
display. The summation and self-read items can be per-tariff or a total of all 4 tariffs,
except for the power outage values, the error counter, which show only totals.
