Lower Tolerance; Upper Tolerance; Systematic Difference - HBM WTX120 Bedienungsanleitung

Supervisor mode

9.2.22 Lower tolerance

This parameter describes the lower tolerance limit for the dosing result. If the
dosing result falls below the tolerance limit, the dosing status is displayed as
"Below tolerance limit", and the correspondingly configured digital output
(Tol.- or Tol.Error) is set. The status is cleared on the next startup.
When re-dosing is active, re-dosing is automatically carried out if the dosing
result is below the lower tolerance limit. When you enter the target weight, the
lower tolerance limit is automatically set to 99.8% of the target weight if no
lower tolerance is set.

9.2.23 Upper tolerance

This parameter describes the upper tolerance limit for the dosing result. If the
dosing result exceeds the tolerance limit, the dosing status is displayed as
"Below tolerance limit", and the correspondingly configured digital output
(Tol.+ or Tol.Error) is set. The status is cleared on the next startup.
When you enter the target weight, the upper tolerance limit is automatically set
to 100.2% of the target weight if no upper tolerance is set.

9.2.24 Systematic difference

Depending on the system, a certain amount of filling material may be lost or
additional material may be added after every filling processes. Consequently,
this shortfall or surplus, which only occurs after checkweighing, cannot be
detected by the optimization process. You can, however, use the "Systematic
difference" function to take it into consideration.
Activate the function with the Syst.diff. parameter, specifying the overfill
(positive value) or underfill (negative value) as appropriate. A maximum of
±5% of the nominal value is allowed.
