Re-Calibrating Your Scale
RE-CALIBRATING YOUR SCALE
To re-calibrate your scale and make it even more accurate, document
several loads of varying sizes and measure the actual weight of all
loads on a certified scale.
In this example, we are unloading six loads onto four semi-trucks.
Example:
Load A 51560
Load B 33240
Load C 17620
Load D 50420
Load E 38200
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 20.
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 20.
