Adjustment - KERN and SOHN PFB 120-3A Mode D'emploi

7.6 Adjustment

As the acceleration value due to gravity is not the same at every location on earth,
each balance must be coordinated - in compliance with the underlying physical
weighing principle - to the existing acceleration due to gravity at its place of location
(only if the balance has not already been adjusted to the location in the factory). This
adjustment process must be carried out for the first commissioning, after each
change of location as well as in case of fluctuating environment temperature. To
receive accurate measuring values it is also recommended to adjust the balance
periodically in weighing operation.
• Observe stable environmental conditions. A warming up time (see chapter
1) is required for stabilization.
• Prepare adjustment weight, see chap. 1.
The adjustment weight you use is dependent on the capacity of the
balance. Perform adjustment as close as possible to the maximum load.

• Ensure that there are no objects on the weighing pan.
Procedure:
 In weighing mode press and hold the MODE key until <UnLoAd> is displayed on
the screen.
or
call up menu item "P2 CAL" and confirm by pressing the ZERO key.
 When display <LoAd> appears, put the necessary adjustment weight (see
chap.1; Technical Data) on the center of the weighing plate.
 Adjustment will be carried out automatically after stability control.
 After successful adjustment „PASS" will be displayed. The balance returns
automatically into weighing mode.
 Take away adjustment weight
