Conveyor Belt Scale
Product Manual
Navigate to
Main Menu > Calibration > Test Weight.
Enter the test weight amount.
Start the belt running empty and follow the instructions on the screen.
The calibration will run for several belt revolutions and then stop.
Pay close attention to the Old Trim and New Trim values on the
Accept Cal
screen.
The
Trim Factor
will ideally be between
.90 and 1.10.
If the
Trim Factor
is close to 1.000, use the following formula to verify the calibration.
(Test Weight Amount / Idler Distance) * Belt Speed * 60) / 2000 = Tons Per Hour
Example: (
100 lbs
. /
4 ft.
) *
400 feet per minute
* 60) / 2000 =
300 Tons Per Hour
If the
Trim Factor
is not in that range navigate to
Main Menu >Totals & Diag > Live Weight.
The
Live Weight
shows the actual force on the load
cells and
Trimmed Live Weight
adjusts the value by
the Trim Factor. If the
Live Weight
isn’t close to the
actual test weight value then weigh the test weights
on a platform scale to confirm the value. Be sure that
there is nothing interfering with the idler, test weight
bar, or load cells.
Check all setup parameters including model number, idler distance, speed sensor,
angle and test weight amount.
Repeat the calibration if any parameters were changed!
