3.3.3 Linearity Calibration
Linearity calibration uses 3 calibration points. The full calibration point is established with a weight on the
scale. The mid calibration point is established with a weight equal to half of the full calibration weight on
the scale. The zero calibration point is established with no weight on the scale. The mid calibration points
cannot be altered by the user during the calibration procedure.
When LINEAr is displayed, press the Yes button to initiate Linearity Calibration.
The display flashes the full calibration point and calibration unit. Place the specified weight on the scale and
press the Yes button.
To choose a different full point or calibration unit (kg or lb), edit the setting as explained in Section 3.2 Menu
Navigation. When the desired setting is displayed, place the specified weight on the scale and press the Yes
button.
The display shows --C-- while the full point is established.
The display flashes the mid calibration point.
Place the specified weight on the scale and press the Yes button.
