Resetting Values (C1SR)
The ZRO-C2A Resetter zeros both the energy registers and tamper counters by direct
connection to the C1SR module. For more information, see the
ZRO-C2A Handheld Meter
Resetter for the CENTRON C1S and C1SR Operating Instructions .
Transmission
The C1SR R300 communicates within the unlicensed 910-920 MHz frequency band. The
transmission frequencies, the frequency hopping pattern, and the time interval between
transmission cycles are random in nature; thus providing a method for avoiding interference
with transmission from other devices.
FCC Regulations
The C1SR 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.
Testing the RF Message
In order to confirm the CENTRON meter is transmitting SCM messages, the meter is
capable of a "factory test mode." If the meter has less than 50 Watt-Hours of accumulated
energy it will enter "factory test mode." The meter will transmit multiple SCM messages in
this mode. This mode is also useful during meter commissioning to verify that the meter is
transmitting when first installed.
1
Place the meter in a socket.
2 Ensure that the meter has less than 50 watt-hours of accumulated energy.
If the meter has more than 50 watt-hours of accumulated energy,
you may use the ZRO-C2A resetter to reset the energy
consumption to 0.
3
Apply power to the meter.
4 Read the meter using a hand-held device or other RF capable reading device. The
meter will continue to transmit multiple RF messages while under the 50 watt-hour
threshold.
