Overwriting the Internal Linearity Weight

The internal linearity weights only should be overwritten if:
• balance was linearized externally
• external span adjustment was performed
• the linearity was tested externally with known weights (calculate a mean
value out of 3 measurements)
• this mean value is two times larger than the standard deviation
The overwriting of the internal linearity weights can be performed different
ways:
1. the way explained in this service manual;
2. using the PSION server; or
3. using the SARTOCAS program for personal computers and laptops.
Usually the internal linearity weights should be overwritten using the PSION
server or the SARTOCAS program for personal computers and laptops.
Only in exceptional cases (e.g. no service software available) the overwriting
routine can be performed using the overwriting program of the balance.
– Make sure that the balance operating menu is set to code" 1 13 1 "
- internal linearization accessible -, and the menu access switch is open.
– Perform an external linearization (see page 17).
– Perform an external span adjustment (see page 19).
– Turn the balance off and back on again by pressing the
– While all segments appear (all 8's are displayed), briefly press the
key.
– Now "C.C." or "C.L." appears above the weighing display.
• "C.C." = overwriting the internal adjustment weight
• "C.L." = overwriting the internal linearity weights
– Press the key until "C.L." is displayed.
– Tare the balance by pressing the
press the key to start the linearity overwriting routine. The display
shows "C".
– The built-in linearization weight(s) is(are) internally applied one after the
other by servomotor and removed at the end of linearization. The weight
value is now read into the EEPROM. Then the balance returns to the
weighing mode.
– After completing the linearization routine, set the balance operating menu
back to code " 1 13 2 " and lock the menu access switch.
– After this the linearity has to be checked again externally.
