RE-CALIBRATING YOUR SCALE
To re-calibrate your scale, document at least 3 to 6 loads of varying sizes and measure the actual weight of all
loads on a certified scale.
•
It must be assured that each truck is not losing grain in transit to a certified scale.
•
Weigh the truck immediately before unloading and immediately after unloading to minimize errors due to
changes in fuel etc.
In this example, we are unloading six carts of grain onto four semi-trucks.
Example:
Cart Load A
51560
Cart Load B
33240
Cart Load C
17620
Cart Load D
50420
Cart Load E
38200
Cart Load F
12360
Total Indicator Weight 203400
Truckload #1
51920
Truckload #2
51320
Truckload #3
50720
Truckload #4
51070
Total Certified Weight 205030
Reading Too High
If the Indicator is reading higher than the certified scale, then the calibration number is high and should be
decreased proportionally. See page 26.
Reading Too Low
If the Indicator is reading lower than the certified scale, then the calibration number is low and should be
increased proportionally. See page 26.
