Re-Calibrating your Scale

RE-CALIBRATING YOUR SCALE
To re-calibrate your scale and make it even more accurate, document at
least 3 to 6 loads of varying sizes and measure the actual weight of all
loads on a certified scale.
•
Weigh the load 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 nutrient onto four semi-
trucks.
Example:
Indicator Certified
Weight Scale Weight
Cart Load A 33660 33900
Cart Load B 33240 33540
Cart Load C 35200 35480
Total Weight 102100 102920
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 38.
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 38.
