External Span Adjustment
Important: Usually the span adjustment should be performed using the internal
adjustment weight.
Only in special cases the RC-/MC-balances may be adjusted externally (e.g.
if the span accuracy of the internal adjustment weight is out of tolerance).
The RC-/MC-balance can be externally calibrated in 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.
Warning! The balance accepts only a weight that is within a tolerance of approx. 2% of
the factory-programmed adjustment value. You can set the balance for
greater adjustment tolerances only using the PSION server or the SARTOCAS
program for personal computers and laptops.
– Unload the weighing pan and press the key (MC) or the key (RC).
– At 0,00000 g is display press the key (MC) or the key (RC) and
keep it pressed (for at least 3 sec.) until the readout on the left is displayed.
– When “ C.I. “ is displayed, press the key until “ C.E. “ appears.
– Tare the balance by pressing the key (MC) or the key (RC), and
press the key to start calibration/adjustment.
– The calibration/adjustment weight is displayed.
– Only MC-balances: Enter the exact weight 200.000xx (see calibration
certificate) using the numeric keys on the balance.
– Center the required weight (200 g) on the weighing pan once again and
close the draft shield.
– After storing the calibration/adjustment weight, the program returns to the
weighing mode.
– Lock the menu access switch.
Important Note! After the external span adjustment the internal adjustment weight has to be
overwritteb (see page 21)!
