Weight Calibration - Intercomp CW250 User Manual

Weight Calibration

One to ten load weights need to be applied to calibrate the scale. Using multiple point
calibration allows the unit to weigh more accurately; by removing undesirable
characteristics of load cells. A typical weight calibration is a three point calibration. This
means three different and optimal loads are applied and entered (not including the zero
point). If you do not conveniently have the three different weights available, you may
also use one or two point calibration. To calibrate with one point, simply turn off the
scale after completing step 13 as listed below. To calibrate with two points, turn off the
scale after completing step 15 as listed below. The CW250 has the capability to apply
and load up to 10 calibration points.
