Linearity

Checking the Linearity

The linearity must be checked according to the Standard Operating
Procedure WKD-038.
– Check the linearity for the entire weighing range in 50-g steps.
– Compare the values displayed with the tolerance ranges given in the
Table of Adjustment Data for Basic
– If the errors exceed the tolerance ranges, the linearity must be adjusted.

Adjusting the Linearity

You can adjust the linearity in these balances only using the SARTORIUS
MC1 Server (version 4.4 and later) or with the SARTOCAS program.
– Activate the BPI mode (see page 8).
– Adjust the linearity using the SARTORIUS MC1 Server (version 4.4 and
later) or with the SARTOCAS program for PCs and laptops.
(Please see the program description for instructions on this automatic
procedure).
Alternative manual procedure:
– When using the balance operating menu, make sure that the
code » 1 9 5 – external linearization accessible – « is set (refer to page
27, "Balance Menu Code Settings").
– Switch on the balance using the e key.
– If necessary, press t to tare the balance.
– Press the q key until the display on the left appears.
– The calibration weight required is displayed. Place the required weight
on the weighing pan.
If the required weight is within 2% of the tolerance range of the displayed
value, the plus sign will go out. If not, the minus sign will appear. Errors
that are too large can be adjusted only with PSION or a PC!
– Remove the weight and, if necessary, press t to tare the balance.
– Repeat this procedure until you are prompted to unload the balance.
– After the zero point value has been stored, the balance will return to the
standard weighing mode.
After working in the BPI mode, make sure to set the write-protect again so
that the balance returns to the standard data record output mode
(SBI mode = Sartorius Balance Interface) and peripheral devices can again
be connected.
