Meter Types
For Residential electricity metering in the Nelson Hydro service area there are currently two main types of meters used;
C1SR: These meters are used mainly on single family residential applications,
CN1SR: These meters are used mainly in apartment and strata developments
RF Transmitter Types
The meters use an R300 personality module to communicate with the meter reading device. The R300 modules used at Nelson Hydro come in two variants as specified by -2 or -3. We have requested further information from the manufacturer on the characteristics of these modules and can summarize the data we currently have as follows.
