New Features Compared to the BP: New, different housings (see Overview, Page 6)
Procedure: Checking the balance/scale 1. Check the repeatability
Balance/Scale with strain gauge system (standard deviation, see page 18)
Balance/Scale with double lever system (standard deviation, see page 23)
Balance/Scale with monolithic weigh cell (standard deviation, see page 28)
Balance/Scale with forked lever system (standard deviation, see page 35)
2. Checking the off-center loading error and adjust as required
Balance/Scale with strain gauge system (see page 18)
Balance/Scale with double lever system (see page 24)
Balance/Scale with monolithic weigh cell (see page 29)
Balance/Scale with forked lever system (see page 36-37)
3. Adjusting the sensitivity with internal calibration weight
Balance/Scale with monolithic weigh cell (see page 32)
4. Adjusting the sensitivity with external calibration weight
Balance/Scale with strain gauge system (see page 21)
Balance/Scale with double lever system (see page 26)
Balance/Scale with monolithic weigh cell (see page 31)
Determine the internal calibration weight as required (see page 31)
balance/scale with forked lever system (see page 38)
5. Adjusting the linearity is preferably performed using the sequential method, or
with calibrated weights,
Balance/Scale with strain gauge system (see page 22)
Balance/Scale with double lever system (see page 27)
Balance/Scale with monolithic weigh cell (see page 33)
Check the internal linearization weights as required (see page 34)
Balance/Scale with forked lever system (see page 39)
Activating the BPI Mode/ Perform only before working with the SARTOCAS Program or PSION; for calibration/
Deactivating write-protect adjustment. Linearization and programming a data record when exchanging the
main PCB.
Reset write-protect After working with the SARTOCAS program or PSION, always make sure to conclude
with the „Close“ function (returning the balance from BPI back to SBI mode),
otherwise write-protect is not set, and the balance/scale remains in the BPI mode
(see Page 11). If all else fails, reset the SBI mode by pressing menu reset (9-1°).
Exchanging the Main PCB When ordering replacement PCBs, always state the model and the serial number, that
is the only way that a new preprogrammed PCB set can be delivered.
Opening the housing - Unscrew the 1 (sealed) screw on the reverse side and slide the upper half of
the housing back.
- After reclosing the balance/scale, the service technician or service organization
must reaffi x another control seal!
Triangular weighing pan - Check the off-center loading error according to the OIML Recommendation R76,
see 4-point test (Pages 18; 24; 29)
- when carrying out adjustment/calibration work using the 3-point test (page 30)
Blue backlighting - Is adjustable and can be switched off
Service software - TradeCAS or SartoCAS starting with Version 1.44
Psion CAS Version 4.9 and later.
Do not use older software versions!
Adjusting the off-center load - On strain gauge, Angled lever and double lever systems perform by fi ling on
monolithic weigh cell with adjustment screws
