Section 10: The “Minimum Weighing” Application

10.4 Working with the “Minimum Weighing” Application

In this Section you will learn how to work with the “Minimum Weighing” application. When you work with “Minimum Weighing” you

can, of course, also specify target values and tolerances and use statistical functions and identifications. You already know these

possibilities from the “Weighing” application (Section 6.3) so they will not be described again here.

Touch the “–>0<–” function key to set the display to zero.

Place the tare (weighing container) on the weighing pan and touch the «1» key

on the terminal to tare the balance. The balance determines the tare value and displays

it in the bottom information field.

The top information field then displays the minimum weighing required for the current

tare (10.0 g in the example at left). The middle information field also displays the tare

reference value (which determines the miniumum initial weight). The small symbol

below the time, and the gray figures of the weighing result, indicate that at the moment

the minimum weighing has not been reached, and the current weight value may

therefore possibly not lie within the tolerances specified by the QA system.

Now place the weighing sample on the weighing pan. As soon as the required minimum

weighing is reached, the small symbol below the time disappears and the weighing

result is displayed in black figures.

Should you wish to weigh further weighing samples, if necessary you can reset the

display to zero with the “–>0<–” function key. Note: The zero setting range is limited

to 10% of the nominal load of the balance. If the total load on the balance (tare plus

sample) is over this limit, zero setting i s not possible. The weighing display then starts

to flash, after a short time the message “Abort" appears, and the operation is terminated.

You can use the «8» key to print the weighing result out. The illustration at left shows

part of an example of a report in which the current tare value and the net weighing-in

are printed. (Depending on your individual settings, your own report may differ from this

example). The star to the left of the net weight indicates that the minimum weighing

according to the above example has not been reached, and the value may possibly not

fulfil the QA requirement.
