The Latest Prove Results is a block of 1310 registers, starting at input register
62400 and proceeding through register 63709. The table below explains these
sub-areas.

Description
Prove Status
62400 to 62409
Occupies 10 registers
Prove Setup
62410 to 62553
Occupies 140 registers and protects meter
configuration and prove setup information
for use by proving calculations and report
generation; this information remains
unchanged from the moment of enable,
regardless of how the original source
information might be altered during or after
the prove
Prove Acceptance
62554 to 62575
Occupies 22 registers and records
timestamps associated with the prove,
accumulator totalizer values, and details of
the disposition of the new meter factor upon
acceptance of the prove.
Prover Configuration
62576 to 62655
Occupies 80 registers and has the same
purpose as Prove Setup, to protect the
prover configuration against subsequent
changes so that proving can proceed under
reliably constant parameters, and so that the
proving report can be generated and
regenerated according to the original
conditions of the prove.
Prove Only Calculations
62656 to 62665
Occupies 10 registers and contains a few
calculated values that are applicable only for
the prove as a whole.
Reading and Calculations for
Prove
62666 to 62781
Occupies 116 registers and the "readings"
part contains the averages of the
corresponding readings for all runs of the
prove. The "calculations" part contains
calculations performed upon the prove-level
readings if calculation method "average
data" was chosen.
Reading and Calculations for
Runs
62782 to 63709
Occupies 166 registers for each of up to 8
runs of the prove. The layout of each block
of 116 registers is identical to that of the
Readings and Calculations for Prove block.
The "readings" part contains the weighted
averages or snapshots of all process input
and counter card input for the duration of the
run. The "calculations" part contains
calculations performed upon the run-level
readings if calculation method "average
meter factor" was chosen.
