4.4 Protected Meter Proving Data in the AFC's Input Register Bank
The data concerned with Meter Proving is maintained in the Input Register Bank,
(Modbus 3xxxxx read-only Input Register Addresses), protected from change
from outside. There are two areas:
a Latest Prove Results (3x63400 to 3x63709)
b Meter Previous Prove Summary (3x61600 to 3x62399, 50 registers per
meter)
These two areas are described in better detail in the following two topics.
4.4.1 Latest Prove Results
This area contains complete details of the latest prove that has been enabled,
including

Prove setup

Prover and proved-meter configuration summary

Prove state

Prove-level calculations

Run-level input and calculations for each run of the prove
This area supplies almost all the information presented on the proving report (the
remaining info comes from the proved meter’s Previous Prove Summary; see
next). The contents of this area persist until a new prove is enabled, so a proving
report may be regenerated at any time after the prove has been completed and
before the next one is started. There is only one such area for all meters on the
AFC module; therefore enabling a new prove for any meter resets the Prove
Results from the last completed prove, regardless of which meters were involved.
