7.7 Net-total weighings
It is useful if a mixture of several components is weighed into a tare vessel and finally
the sum weight of all weighed components is necessary for control purposes (net-
total, i.e. the weight of the tare vessel).
Example:
Put tare vessel onto weighing plate, tare with key to „0“.
Weigh component n and tare with key (Memory) to „0“. The memory activation is
indicated by a triangle on the left border of the display.
Weigh component o, when pressing the key appears the net-total, that means,
the sum weight of the components n and o. Tare to „0“ using the key.
Weigh component p , when pressing the key appears the net-total,
i.e. the sum weight of components n and o and p.
If necessary, also fill the formula up to the desired final value.
Back to weighing mode by pressing the key.
7.8 Percent weighings
Display symbol: %
Percent weighing allows to display weight in percent, in relation to a reference
weight.
Switch-on the balance using the
key and wait for the „0“ display.
Press the key several times shortly. The reference quantities of the counting
function are passed through, after that „100%“ is displayed.
Place the reference item on the weighing pan.
Press
key, the weight of the item is taken over as reference (100%).
Now you can place the test objects onto the weighing plate; the percentage to
reference item is displayed.
Back to weighing mode by pressing the key.
