4. Matching EZ scale to another scale
Sometimes two different scales are used to weigh the same load. When this is done, the weight
measured by each scale may not be the same. This can be caused by one or both of the two scales
being slightly out of calibration. This indicator has the ability to match any other scale, even if
that scale is not calibrated.
To match your EZ scale (Scale A) to another scale (Scale B) you must determine the Calibration
Multiplier. To do this, place a load on Scale A (feed wagon, etc...) and write down the weight
displayed. Repeat several times to determine the average weight. Next, place the same load on
Scale B and again write down the weight displayed.
Repeat several times to determine the average weight. Use the following formula to determine
the Calibration Multiplier for the EZ’s "CAL" number:
!
It is important to use an average of several weights before calibrating the scale.

1.026 +
1.018 = 3.064
B ÷ A
3.064 ÷ 3 trials = 1.021 Cal. Multiplier
New EZCAL# = Orig. EZCAL# × Cal.Multiplier
24484 = 23980 × 1.021

You should not modify your "SETUP" number. Only your "CAL" number.
