Section 5 - Calibration and sealing
For best results, calibrate at or near full capacity. Calibration unit can be set to either kg or lb. When the scale is
used in Legal for trade applications, the calibration menu is locked out and is not accessable. This is to prevent
unauthorized personnel from changing calibration. Before beginning calibration, make sure masses are available. If
you begin calibration and realize calibration masses are not available, exit the menu with a short press of the
ON/
ZERO OFF button. The scale will retain previously stored calibration data. Calibration should be performed as
necessary to ensure accurate weighing. Masses required to perform the procedures should be in compliance with the
specification requirements of the scale being used.
Ranger Counting scales offer a choice of two calibration methods: Span Calibration, and Linearity Calibration.
Span - Span calibration ensures that the sale reads within specifications using two weight values: zero and a weight
value close to 100% of the full capacity. Special software features enable you to span calibrate at a number of
lesser values which varies with the model of the scale.
Linearity - Linearity calibration minimizes deviation between actual and displayed weights within the scale’s weigh-
ing range. Three weight values are used: zero, a weight value at midpoint of the scale’s weighing range, and a
weight value at or near the specified capacity.
Before beginning calibration, make sure masses are available. If you begin
calibration and realize calibration masses are not available, exit the menu.
The scale will retain previously stored calibration data. Calibration should
be performed as necessary to ensure accurate weighing.
