7.6.4 Automatic formula processing with “% Components” (relative nominal values)
Automatic formula processing with “% Components” is basically identical to formula processing with “Fix Components”. Therefore, the
procedure is only described in brief below.
Depending on the basis for weighing in components, which is specified in the formula
definition (section 7.5.2), when the formula is called up you will first be prompted to enter
the desired final weight of the formula or the nominal weight of the first component.
Enter the required value.
The example opposite shows the prompt for entering the final weight.
Once the final weight (or the nominal weight of the first component) has been entered,
you are prompted to tare the balance. Place the weighing container on the balance, press
the «H» key and the balance is then ready for weighing in the first component. The
nominal weight is displayed in the “Nominal” information field and the SmartTrac supports
you when weighing in the nominal weight.
Weigh in the first component. The “Abs/Diff” function key can also be used to switch the
weight display between the quantity of a component already weighed in and the remain-
ing quantity to be weighed in. When the nominal weight is reached or the weight is within
the tolerances, press the “M+” function key to save the value.
Weigh in the other components. Once the last component has been weighed in, the results
window appears automatically and the formula record is closed.
