8.4.3 Counting to a nominal value
The “Piece Counting” application offers additional functions that simplify counting to a defined Nominal value. These functions can be
used for both single piece counts and series counts when using the statistics. The following description assumes that the reference for
the piece count has been determined already.
Presettings
The function keys shown at left must be activated so that a nominal weight and the
corresponding tolerances can be entered (section 8.3.3). To view the defined values in
the display, the information fields of the same name can also be activated, if necessary
(section 8.3.4).
We also recommend activating the “Abs/Diff” function key, so that you can switch between
the quantity already weighed in and the quantity that remains to be weighed until the
nominal value is reached.
Operating sequence
Note: If values are already present in the statistics, the function keys for entering the
nominal weight and tolerances are inactive. In this case the statistics must be deleted
using the “CL Result” function key before the nominal weight and the tolerances can
be defined.
Press the “Nominal” function key. Type in the desired value. Check the weighing unit,
which is shown to the right of the nominal value. When the weighing unit is touched a
selection box containing the available units, including “PCS” (Pieces), appears. Note: The
“PCS” unit is available only if a reference piece weight has been determined. The units
are not converted automatically; i.e., if a value is entered in one unit, this value remains
the same even if the weighing unit is changed.
Once the value is entered, press “OK” to activate the nominal value.
The “+Tolerance” and “-Tolerance” function keys can be used to specify the accuracy
with which you wish to count. The input window is the same as for the nominal value. Both
tolerance values are set to 2.5 % ex works. Instead of a percentage value, you can also
enter an absolute tolerance in any weighing unit (e.g., “PCS”). Once the relevant value is
entered, press “OK” to activate the tolerance. Piece counts that are outside the tolerance
range are specifically marked (“>T” and “<T”) when the single values are printed.
As soon as the nominal value and tolerances have been entered, a graphic weighing-in
aid (“SmartTrac”) appears in the display with tolerance markers that simplify weighing
in to the nominal value: You can roughly weigh in your samples until the lower tolerance
value is reached and then accurately dose, if necessary, up to the nominal value.
