Physical Description
The CP1SR personality module is constructed of a flame retardant printed circuit board
material which supports the discrete, surface-mounted, and integrated circuit components. A
microstrip etched on the circuit board serves as the RF antenna. The CP1SR personality
module easily snaps into the meter module mounting bracket. This module is then
electronically attached to the metrology board via a board to board connector. The following
information is sent to the personality module from the base metrology board:
Line voltages
Energy data
Basic status information
The CP1SR contains contacts on the module board, located at the 12 o'clock position behind
the LCD, for resetting the energy register and tamper counters. This can be accomplished
with the ZRO-C2A Resetter.
The CP1SR uses a unique module identification number, provided by Itron. This ID number
is contained in each message transmission and is used by the handheld and billing system to
determine meter identity and location. This ID number, which is contained on a bar-coded
label, is placed on the LCD housing directly above the LCD display.
Registers
Display
The CP1SR personality module is only available with a liquid crystal display, LCD. The
LCD is automatically adjusted for contrast over the operating temperature range.

This module can be configured to display either four or five digits of energy consumption
and will rollover at 100,000 kWh for all meters. The self-contained meters can be
programmed to display normal kWh consumption (5X1 register configuration) or tens of
kWh consumption (4X10 register configuration). If the CP1SR is programmed for a 4x10
display, a “Mult by 10" label is placed on the module to the left of the LCD display. Thus,
the actual energy consumption is obtained by multiplying the value on LCD display by 10.
