4.2.2.2 Initial Installation and Change-outs
When an RMTR is installed, it must be configured for operation.
The installer must note the:
• Serial Number of the RMTR that is installed
• Date
• Customer number
• Initial dial reading
• Meter type
• Service Type
• Number of dials
• The unit of measure as displayed on the dial face
• The multiplier to convert pulses to a valid dial reading
• Any other items required by the utility’s process
The installer, using an HHTR must configure the RMTR as to the:
• Service Type (Water / Gas)
• IED configuration (Encoder vs. pulser operation, selecting the appropriate
supported model).
• Number of dials
Once the RMTR is installed, a nearby EMTR must be selected by the installer to convey
the data. The installer must use the HHTR tool to make this assignment in the EMTR.
The installer should test the system after all of the devices have been configured. The
installer can use the HHTR to cause the RMTR to initiate a data upload to the EMTR.
The tool will confirm that the test was successful.
The change-out process is just like a new installation of the RMTR described above, with
the exception that any previous EMTR assignments should be reused, or accounted-for,
with the use of the new RMTR.
4.2.2.3 RMTR Operations
The RMTR wakes up once an hour (hourly after the freeze time; for example: if the
freeze time is at 9:15 actual time, then hourly updates will occur at 10:15, 11:15, and so
on) to obtain a reading and updates its present total consumption register. In the case of a
dial encoder it wakes up once an hour to read the encoder then write a table. In the case
of a pulser it wakes up to record a pulse event, and also once an hour (relative to the
freeze time) to update the table.
