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.

SETUP # 127060
CAL#
23980
1 trial 2 trial 3 trial
Scale B 30,000 30,580 28,000
Scale A 29,440 29,800 27,500
1.020 + 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.
