MC 5
Adjusting the Linearity:
Important Note:
Whenever possible, linearize the microbalance only by using the PSION server or the Sartorius CAS
program written for personal computers and laptops.
- Set menu code >> 1-12-1 << - external linearization accessible -
on the microbalance (see page 40 of the "Overview of the
Balance Operating Program“ aand page 19 "Accessing the
Balance Operating Menu").
- When the display shows 0.000 mg, hold down the key for
more than 3 sec. You will see the display shown on the left.
- Use the key to „scroll“ through the menu until >> L.E. <<
appears in the upper right-hand corner.
- Tare the microbalance using the key and press the key
to activate the linearization routine.
- The first linearity weight is now displayed.
- If necessary, use the numeric keys to enter a new, accurate
weight 5.0000xx (see Weight Certificate to enter the correct
value).
Important Note:
The microbalance will accept only a weight that is within a tolerance of approx. 2% of the factory-
programmed linearity. You can set the microbalance for greater linearity variations only using the PSION
server (approx. 8% of the factory-programmed linearity) or the CAS program for PCs and laptops (in this
case, the linearity is adjustable from 0 to 100% of the factory-programmed value).
- Open the draft shield.
- Center the required weight on the pan and close the draft shield.
- After the weight has been accepted, the next linearity weight will
be displayed.
- Center the required weight on the pan and close the draft shield.
- Follow the same procedure outlined above to have all linearity
points recalled and the new weights accepted and stored by the
microbalance.
- At the end, you will be prompted to unload the microbalance.
- After the zero point has been stored, the microbalance will return
to the standard weighing mode.
- Now check the linearity again.
- At the end of the linearization routine, reset the menu code to
>> 1-12-2 << (external linearization - access denied).
For directions on how to overwrite the internal linearity weight, see page 31.
