CALIBRATION NUMBER
The “CAL” number is adjusted to make scale read proper weight for different
load cells and to make accuracy adjustments on a scale system. Systems
should be checked with known weights and adjusted if necessary to insure
accuracy. Both setup and calibration numbers are changed to convert a scale
from lbs to kgs.
Calibrating Scale For Maximum Accuracy
Note:
To accurately calibrate scale, you need a large amount of weight that
has a known value. For best results you should have at least as much weight
as largest load you plan to weigh.

Calibration Numbers

1. Press to Zero-Balance.
2. Put KNOWN WEIGHT on scale
platform and write down DISPLAY
