An example of calculating the material factor is:

what you want

what you’ve got X 100 = Material Factor

4.23 Span Error%

this is the percentage of error calculated during the
span calibration. The relation between the calculated
span and the actual registered span.

4.24 Zero Counts

This parameter illustrates the raw dead load counts of
a calibrated system. This value can be recorded and
entered manually in the event of a complete integrator
replacement.

4.25 Zero Error%

This is the percentage of error calculated during the
zero calibration. This is a direct relation between
theoretical zero and actual zero with dead load on the
load cells.

4.26 Idler Spacing

This parameter defines the spacing between the idlers.
It also determines the weighing surface of the belt
scale.

Refer to Section 1.3.3 on page 9 to determine your
idler spacing. That number is the number that is
entered into the integrator Idler Spacing parameter.

If the unit of measure is in feet, this value is entered in
inches. If the unit of measure is in meters, this value is
entered in meters.

The default value of this parameter is: 48 inches.

4.27 Number of Idlers

This parameter defines the number of idlers in a
system.

Enter the number is idlers being used in the system
using the numeric keypad and press

enter

.

The default value for this parameter is: 1.

4.28 Belt Test Revolutions

This parameter defines the number of conveyor belt
revolutions the unit will make after the belt speed
calibration is done. The operator will key in the
number of full belt revolutions the unit will make for
the deadload and span calibrations. The deadload, or
zero calibration is a calibration that runs for a
pre-determined amount of time during which the belt
is running with no material on it. The span calibration
is a calibration that runs for the same pre-determined
amount of time with a known weight applied to the
scale.

The default value for this parameter is: 1.

4.29 Pulses per Revolution

This value is the number of pulses recorded for a
complete revolution of the belt. This value can be
recorded and entered manually in the event of a
complete integrator replacement.

The default value for this parameter is: 3600.

4.30 Belt Length

This is the total length of the conveyor belt. This value
can be recorded and entered manually in the event of a
complete integrator replacement. An easy way to
measure the belt length is to spray paint a marking on
the belt. Run a tape measure down to the other end
and times it by two to get the total belt length.

Enter the total belt length being used in this system
using the numeric keypad. Press the

enter

key to save

that value.

The default value for this parameter is: 600.

4.31 Belt Angle

This is the angle of the conveyor measured in degrees.
this should be used when using the BCi integrator
with weigh frames containing only one or two load
cells.
