Chapter 6 Counting Mode Technical Reference Manual
significant vibrations due to heavy machinery operating
nearby or poor support conditions can increase the
sampling error of the Model 574. For example, entering
a value of 2 would reduce the claimed accuracy of the
Model 574 in half for a given sample weight. The
entered value may be between 0.1 and 20. Numbers less
than one will increase the calculated accuracy of the 574.
Since the 574's decision as to when it can and cannot
enhance is based upon the it's calculated accuracy, the
value entered here will affect the maximum number of
pieces which may be added and still allow the
enhancement to take place.
P186 PreSm
Pre-Sample: This parameter permits 4 choices; none,
scale 1, scale 2 and scale 3. If the parameter is set to a
particular scale number, if the operator presses the
<SAMPLE> key, the 574 will switch to Scale 1, 2 or 3.
If "none" has been selected, the 574 will remain on the
presently selected scale.
P187 AftSm
After Sample: This parameter permits 4 choices; none,
scale 1, scale 2, and scale 3. If the parameter is set to a
particular scale number, after a sample is completed, the
574 will switch to Scale 1, 2 or 3. If "none" has been
selected, the Indicator will remain on the presently
selected scale.
6.4 COUNTING MODE LISTING
The <SELECT> key will advance the 574's mode to the
next mode as programmed in the setup mode P300 -
P309. Alternatively, keying a mode number then
pressing <SELECT> will change the 574's current mode
to be the mode whose number was keyed in. The
following eight modes are Model 574 counting related.
See table 6.
30 QUANTITY
The current net weight is divided by the current piece
weight, resulting in the current quantity. This value may
not be entered.
31 QUANTITY TOTAL
This mode displays the current total accumulated
quantity. The value displayed is the result of previous
additions of the displayed quantity to the previous total
quantity.
It operates the same as mode 3, the gross total mode.
The largest value that can be displayed is 999,999. If a
larger value is achieved, the display will read "Code04
#> Dsply". However the stored total is still active and
accumulates may continue to occur. These larger values
may be printed without any problem. If the value
exceeds 3,000,000 internal rounding will be performed.
Theoretically this value is 16,777,216.
32 QUANTITY TOTAL PLUS CURRENT
This parameter holds the accumulated quantity plus the
currently displayed quantity. For example if the quantity
total register (parameter 31) holds a value of 100 and 13
more parts were added to the scale, then this register
(parameter 32) will yield a quantity of 113.
33 QUANTITY TOTAL - CURRENT
This parameter holds the accumulated quantity minus the
currently displayed quantity. For example if the quantity
total register (parameter 31) holds a value of 200 and 10
more parts were added to the scale, then this register
(parameter 33) will yield a quantity of 190.
34 PIECE WEIGHT
This register holds the value of the average piece weight
established after a sample routine.
35 PIECE WEIGHT x 1000
This register holds the value of the average piece weight
times 1000. This value is calculated after the piece
weight value is established.
36 PERCENTAGE ACCURACY ACHIEVED
This register contains the percentage of accuracy
achieved after a sample routine. Refer to table 4 to
determine the percentage of full scale weight that must
be added to the platform to achieve the desired accuracy
requirements.
37 LAST SAMPLED AMOUNT
This register holds the quantity of the last sample size
