Operation: CP1SR Version
70 CENTRON® OpenWay™ Meter Technical Reference Guide
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 (ERT) 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.
FCC Regulations
The CP1SR communicates in the unlicensed, 910-920 MHz band governed by the US Code
of Federal Regulations (CFR) Title 47, Part 15 Radio Frequency Devices, Sub Part C
Paragraph 247 Intentional Radiator.
Changes or modifications not expressly approved by Itron could void
the users authority to operate the equipment.
Tamper Detection
The CENTRON Polyphase CP1SR features the Itron patented method of tamper detection
that senses both meter removal and meter inversion. The removal tamper (RTPR)
increments a counter each time the meter is abruptly removed from a live meter socket. The
tamper counter utilizes a tilt switch to detect when the meter is removed from a meter
socket.
Testing the CENTRON Polyphase CP1SR Tamper Counter
SCM Testing
In order to test the power removal counter, the meter must sense a shaken condition
associated with a power outage.
