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
200.000
xx (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)!
