Note:
You must close the balance housing before adjusting the off-center loading
error. Deactivate the »Auto Zero function 1 6 2 « and switch the application
filter to »standard weighing 1 2 1 «.
To adjust the off-center loading error, change the settings of the off-center
load thumbscrews.

protective caps (113) located on the rear panel of the balance are removed.
For the adjustment, you will need the following:
– Off-center load adjustment key
– Test weights
– Remove both capped plugs (113) from the rear panel of the balance

shield and press t to tare the balance.
– Place the test weight in positions B through C in sequence and write
down the values, with the respective plus or minus sign, displayed at
stability and with the draft shield closed.
Example: (BP210D):

position B corresponding to the off-center load thumbscrew on the right.
