External Linearity Adjustment (only MC-Balances)
Important Note! This adjustment should only be performed in exceptional cases and only on
MC-balances (only on MC-balances you have the possibility to enter the
exact weight values of the necessary linearity weights using the numeric
keys).
– Make sure the balance operating menu is set to code “ 1 12 1 “
- external linearization accessible - .
– At 0,00000 g display press the key and keep it pressed (for at least
3 sec.) until the readout on the left is displayed.
– Press the key until “ L.E. “ is displayed.
– Tare the balance by pressing the key and press the key to start
the linearization routine.
– The first linearity weight value is displayed.
– Alternatively, enter the exact weight 50.000xx (see calibration certificate)
using the numerice keys on the balance.
Warning! The balance accepts only a weight that is within a tolerance of approx. 2%
of the factory-programmed linearity. You can set the balance for greater
linearity tolerances only using the PSION server or the SARTOCAS program.
– Open the draft shield.
– Center the required test weight on the weighing pan and close the draft
shield.
– Once the weight value is stored, the next linearity value will be displayed.
– Center the required weight on the weighing pan once again and close
the draft shield.
– Alternatively, enter the exact weight 100.000xx (see calibration certificate)
using the numeric keys on the balance.
– The linearization weights to be loaded are displayed on the balance one
after the other and the values are stored.
– Finally, you are prompted to unload the balance.
– After the zero point has been stored, the program will return to the weigh-
ing mode.
– Afterwards, recheck the linearity.
– After adjusting the linearity, please set the balance operating menu back
to code “ 1 12 2.”
Important Note! After the external linearization the internal linearization weights have to be
overwritteb (see page 20)!
