5.2. Features / Basic functions
Theoretical Calibration
In addition to the capability of adjusting the A810 by using calibrating weight a theoretical calibration via
the characteristic value and rated load of the load cells is also possible.
Auto free fall compensation
The automatic free fall compensation (AFFC) provides closer tolerance and better
accuracy in batching application.
Selfcheck and Watchdog
To insure function and reliability of the complete system well proofed self check procedures and a
watchdog function are provided.
Accumulation Function
The A810 accumulation function continuously updates the material throughput and monitors the total sum
and the counts for each code group separately.
Feeding-/ Discharging weighing
The A810 allows an accurate feeding or discharging process controlled by a set of weighing control
parameters.
For comparison there are the simple comparison and the sequence mode selectable.
