Linearity
Checking the Linearity
Note: The linearity must be checked according to the Standard Operating Procedure
WKD-038.
- Check the linearity of the balance/scale for the entire weighing range in 50-g
steps.
- Compare the values displayed with the tolerance ranges given in the „Table of
Calibration/Adjustment Data“ on pages 42-43.
- If the errors exceed the permissible tolerance ranges, the linearity must be
adjusted.
Adjusting the Linearity
Caution! You can adjust the linearity on CP balances/scales only using the SARTORIUS MC1
Server Software (Version 4.9 and later) or with the SARTOCAS program.
- Activate the BPI mode (see page 15).
- Adjust the linearity with the SARTORIUS MC1 Server (Version 4.9 and later) or
with the SARTOCAS program (Version 1.44 or later) for PCs and laptops.
(Please see the program description for instructions on this procedure!).
Alternative manual procedure:
- When using the operating menu, make sure that the code „1 9 5 -external
linearization accessible“ is set (refer to page 13-14 „Operating Menu Settings“).
- Switch on the balance/scale using the e key.
- If necessary, press t to tare the balance/scale.
- Press the q key until the display on the left appears.
- 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 PC!
- Remove the weight and, if necessary, press the t key 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/scale will return to the
standard weighing mode.
Caution! After working in the BPI mode, make sure to set the write-protect again so that
the balance/scale returns to the standard data record output mode (SBI mode =
Sartorius Balance Interface) and peripheral devices can be connected.
Note: (SBI mode = Sartorius Balance Interface Mode)
(BPI mode = Binary Processor Interface Mode)
