Overwriting The Internal Calibration Weight - Sartorius Basic plus Service Manual

The balance only accepts weight values within a tolerance range of approx.
2% of the nominal value. Deviations exceeding this tolerance range can only
be compensated using the Sartorius MC1-Server (tolerance approx. 50% of
the nominal value).
- Place the required weight in the middle of the weighing pan and, if you are
using a balance with a draft shield, close the draft shield.
- After the calibration weight is stored, the balance returns to the standard
weighing mode.
- After completing the adjustment, reset the "1 9" code setting in the balance
operating menu.

Overwriting the Internal Calibration Weight

The factory setting of the internal calibration weight is performed very
accurately:
- If overwriting becomes necessary, this indicates a mechanical or electrical
error !
- The balance must be allowed to warm-up (at least 4 hours) !
- The weights must be sufficiently accurate
(check the calibration certificate ! ).
There are various ways of overwriting the internal calibration weight on
Basic balances with brass-system (small).
