Configuring the Meter

6.1.

Configuration Port

The ability to configure the meter is provided through a secure meter configuration port. A cover
mounted optical configuration port accommodates meter configuration by the user. The configuration
port is designed to be used in a meter shop ambient environment, requiring that it function in a room
temperature environment under room ambient lighting conditions. The configuration port interface
supports a read/write security function. The configuration port can be completely disabled such that
meter communications cannot be enabled without breaking the meter security seal. This option is
available for utilities that require the meter seal to be broken and cover removed to allow
reconfiguration of the meter.

Initial Power-Up and Operation

KWH FOCUS
meters are always shipped programmed in a configuration defined at the time an order
is placed. They are ready for field installation.
6.1.2

Billing Data Reset/Preset

The contents of the –kWh and +kWh accumulation registers are user programmable through an optical
configuration port. In its simplest form, this feature allows the user to reset the contents of the +kWh
and –kWh accumulation registers. This feature also enables the user to clear any accumulated energy
following meter verification testing.
The user also has the ability to enter initial energy values into the +kWh and –kWh accumulation
registers. This feature allows a user to pre-load energy values into a replacement meter before it goes
into service.
The user can perform this function in a meter shop
6.1.3

Display Multiplier

The user has the ability to program a display multiplier. kWh values contained in the energy registers
are multiplied by the display multiplier prior to being displayed in the LCD. The display multiplier does
not affect the contents of the internal energy registers. If direct reading is desired on transformer rated
installations, it can be accommodated via this programmable multiplier.
The display multiplier multiplies the displayed energy value(s) by N for 1 ≤ N ≤ 240. N is an integer
value.
