5. CALIBRATION AND SEALING

Span calibration ensures that the Scale reads correctly within specifications. For best results, calibrate at full capacity.
Calibration unit can be set to either kg or lb.
NOTE: 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. The Scale will retain previously stored calibration data. Calibration should be
performed as necessary to ensure accurate weighing. You have a choice of either span or linearity calibration. Span
calibration checks zero and full span calibration points. Linearity calibration checks zero, mid span and full span
points.
Before calibrating the scale, first determine if a recalibration is really needed. Place the available calibration masses
onto the platform. As each mass is added, the scale display should show the correct weight to within +/- 1 scale
division. If the scale is within the tolerance, there is no need to recalibrate the scale.
If it is determined that the scale must be recalibrated do not continue until you are certain that you have suitable
calibration masses.
If calibration masses are available you must select the correct calibration units (pound masses or kilogram masses)
before calibrating the scale. The desired unit can be chosen in the setup menu on page 10.
After the desired calibration unit has been chosen, advance to the LOCSW menu to turn the calibration lock switch off.
This software lock is in place to prevent accidental calibration.

IMPORTANT:

Procedure
TURNING CALIBRATION LOCK SWITCH OFF
To turn the software lock off:
Press and hold the G/N/T/ MENU button until MENU ap-
pears. Release it and SETuP appears. (if already in the
main menu, skip to the next step).
Repeatedly press the PRINT/ UNITS button until LOCSW is
displayed.
Repeatedly press the G/N/T/ MENU button until LCL ON is
displayed.
Press the PRINT/ UNITS button to scroll through the choices
until LCLOFF appears.
Press the G/N/T/ MENU button repeatedly until the scale
returns to weighing
Before calibrating, make sure that you have the correct
masses available:
