6.7

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 during the initial start-up, after change in location and
variation of surrounding temperature. It is also recommendable to adjust the balance periodically during
weighing operation in order to obtain exact measured values.
6.8

Adjusting (go to 7.2.6)

Using a precision weight, the accuracy of the balance can be checked at any time and adjusted.
Warning:
With verified balances, this precision adjustment is not possible
Adjustment procedure:
Check that the surrounding conditions are stable.
A short warm-up time of about 15 minutes is recommended for stabilisation.

6.8.1 Adjusting for verification (KERN 573; FKB-M; KB-NM; FCB-M; DS-M)

General Information:
Prior to the procedure of verification the balance has to be adjusted.
Remark: The adjusting is only possible when not being blocked by the adjusting switch.
The switch for this step is located at the bottom of the housing between the two turning feet.
At the model FKB the cover plate from the housing bottom must be removed.
Switch to the right

572/573/KB/DS/FKB/FCB-BA-e-0957
Adjusting function is released.
This setting has to be selected before starting the adjusting.
Executing the adjusting according to chapter 7.2 "Operation".
After the adjusting has been completed successfully it is nec-
essary to turn the adjusting switch to the left for blocking.
Adjusting function is blocked.
After the adjusting has been completed successfully the ad-
justing has to be blocked by switching to the left.
The balance is now prepared for the procedure of verification.
After the verification the adjusting switch has to be secured by
a verification mark against access.
