9.6. Obligations with Legal for Trade Scales
The operator is responsible for the first and all regularly recurrent official calibrations.
Important: The official seal may only be broken by authorized qualified staff.
If one or more of the following changes has happened, the operater has to send a written note to the assigned
public authority and a new official calibration is mandatory:
► Broken seals
► Replaced load cells
► Replaced load carrier
► Replaced wiring
► Replaced LDUs
► Replaced weighing system controller
► Replaced descriptive plate
► Calibration of the scale
► Changes to the approved software settings
Hint: The user is responsible for the correct performance of any official calibration.
9.7. Legal for Trade Data within the Weighing System Controller
In legal for trade and industrial applications all calibration data will be stored in a flash memory on the weighing
system controller. These data can only be accessed, if the authentification of the FlintWeigh II Software to the
weighing system controller is valid. If these data will be saved during a calibration, the electronic calibration
counter (TAC) will automatically increased by one. The stored data is the following:
Structure of the general scale data
Serial no. Up to 17x per controller; up to 16x type RC3D digital load cell respective LDU
Gravitational factor Default value: 9.8075656
Calibration counter
Programme version x._
Programme revision _.x
Corner correction Max. 16 data records for up to 16x type RC3D digital load cell
Checksum EXE CRC16 for complete programme code
Checksum CRC16 for general scale data
A copy of the general scale data is saved in the file “NW1000.CFG”.
Structure of the individual scales (3x for Scale 1, Scale 2 and Dual scale
)
Scale interval 3x for up to three ranges
Decimals
Unit
Min. capacity Default value: 20e
No-motion
Calibration weight
Max. capacity Max. capacity + 9e = overload
Changeover threshold 2x per scale (up to 3 ranges per scale)
Curve linearisation Up to 5 points per scale
Zero point (Dead load pt.)
Gain value
Scale type Single-interval, Multi-range, Multi-interval
Checksum CRC16 for scale data
A copy of the individual scale data is saved to the file “NW100x.CFG” (x=1..3).
