This section covers the internal features available for an I-210+ meter, along the
AMI modules that are available for the I-210+.
Softswitches
The I-210+ meter offers a set of features which are disabled by default. The I-210+
upgrade features can be individually enabled, either in the factory before shipment
or after receipt by a customer, through a mechanism referred to as a softswitch. A
softswitch feature may subsequently be disabled, for example to allow the
customer to reuse the softswitch when a meter is replaced or moved.
MeterMate is required to upgrade or downgrade the softswitch. If any unsupported
softswitches are set, the meter shall clear all of the softswitches. The softswitch
features supported in the I-210+ are:
*Available only when the internal disconnect switch is installed (unavailable in Meter forms 12S/25S).
O: Communication
The O softswitch enables AMR communication. After installing the O softswitch,
the meter will support one of the following communication types: PSEM, SPI-1,
SPI-2 or quadrature pulse. Default AMR communication type is AMR PSEM.

: Voltage Event Monitoring
Sags and swells are th
e most common types of power quality disturbances. The
I-210+ meter counts both sag and swell events. A swell is the presence of line
voltage above the nominal voltage for a defined period of time. A sag event is the
presence of line voltage below the nominal voltage for a defined
period of time. The
I-210+ meter has two programmable thresholds for Swell and Sag voltage and one
programmable threshold for the duration. When enabled, the user can also elect to display

on the three segment display on the bottom left of the LCD (see
