Tariff/Display Scheme Verification

The meter generates a checksum (CRC-16) of the tariff/display scheme currently residing in the
meter. The checksum can be included as part of the display sequence, and also compared with a
tariff checksum generated by the Power Master Unit. This allows quick verification, either locally
or remotely, that the correct tariff/display scheme resides within the meter.
