Section VI – AccuLoad III Automated Proving Mode
MN06146 Issue/Rev. 0.1 (7/10) 12
Automated Proving Mode
The AccuLoad III firmware provides an automated
proving mode of operation. This feature allows the
operator to prove the meter on all four products, and
four meter factors and associated flow rates for each
product without having to enter the program mode for
each product and meter factor. When the automated
proving mode is activated, the AccuLoad will calcu-
late the meter factor for a proving run based on in-
formation that is obtained during the prove. The op-
erator can select the flow rate and meter factor that is
being proved through the keypad of the AccuLoad.
After the prove is complete, the operator enters the
prover volume and prover temperature and the Ac-
cuLoad calculates the new meter factor. The operator
has the choice of accepting the new meter factor or
ignoring it. The AccuLoad also has the capability of
providing an average meter factor over a maximum of
ten proves.
Entry to the Automated Proving Mode will require
several conditions to be met.
1. The Automated Proving Mode must be enabled
via System Code 321.
2. The programmed security must be met. Then
when normal conditions are met for starting a
transaction (pressing the "SET" key or receiving
authorization via communications), the Auto-
mated Proving Mode will be activated.
3. To initiate the proving sequence, the AccuLoad
will prompt for the prover coefficient of cubical
expansion. Note that the most recent value for
this entry will be displayed. If this value is ac-
ceptable, the operator need only press "ENTER."
Enter Prover Coefficient
-> 0.000186005

4.
The AccuLoad III will prompt for the low flow start
volume. If low flow start is not desired, enter zero.
Press "ENTER."
Enter Low Flow Start Volume
-> 100 Gal

5. Next, the AccuLoad III will display the "Select
Recipe" prompt. If in remote control communica-
tions mode, only those recipes allocated will be
available for selection. Recipes must be selected
before the meter factors, since the recipe deter-
mines the product being proved. Note that only
recipes comprising 100% of a single product may
be delivered when proving.
Select Recipe
-> Recipe 1
Recipe 2
Press PRINT for help
Using the up and down arrow keys, select the re-
quired recipe.
6. The operator must next select the meter factor
and associated flow rate for proving.
Select Meter Factor to Prove
-> #1 0.99850 600 GPM
#2 0.99999 400 GPM
#3 1.00000 200 GPM
#4 1.00055 100 GPM
Move the up or down arrow keys to the meter factor
associated flow rate that is required. Note that only
those factors currently programmed will be offered as
selections. Press ENTER after entering the selection.
7. Enter the batch amount desired.
Recipe 1
Enter Preset Volume
-> 1000 GAL
Press START when ready
8.
Press "START" to begin flow. The flow rate asso-
ciated with the selected meter factor will be used
as the high flow rate. The batch will be delivered.
The flow rate ramp-down from first trip to the end
of the batch will be the same as if not proving.
If after the batch is completed the operator presses
"PRINT," the display reverts to the Ready Mode
display and will not go through the Auto Prove
Sequence.
