Operating instructions

The “Weighing” application

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.

Press the «G» key to set the display to zero. Place the tare (weighing container) on

the weighing pan and press the «H» key to tare the balance. The balance determines

the tare value and displays it in the “Tare” information ﬁeld. The “Net” icon (net weight)

appears next to the weight display.

The “MinWeigh” information ﬁeld displays the minimum initial weight, which is required

for the current tare (20.00g in the example opposite). In addition, the tare reference value

(which determines the minimum initial weight value) is displayed in the “Ref. Tare” informa-

tion ﬁeld. Note: If several reference tare values (and their corresponding minimum initial

weight values) have been programmed by the service technician, the displayed value

automatically changes to the range for the current tare weight. The required minimum

initial weight value also changes simultaneously.

In the illustration opposite, the small weight icon (status icon) and the gray color of the

weight value indicate that the minimum initial weight value has not yet been reached

and that the current weight value may be outside the tolerance range speciﬁed in the

QA system.

Place the weighing sample on the pan. As soon as the required minimum initial weight

value is reached, the weighing result is displayed in dark, easy-to-read ﬁgures and the

small weight icon disappears.

The weighing result can be printed using the «F» key. The illustration opposite shows an

excerpt from a sample printout, which lists the speciﬁcations for the “MinWeigh” function

(method, reference tare and required minimum initial weight value) as well as the current

weight values. The asterisk to the left of the net weight indicates that, according to the

example above, the minimum initial weight value was not reached and that the value

may not meet the QA speciﬁcations.

Note

If the status icon opposite (small weight symbol with clock) appears in the upper right

of the display (below the date and time), it’s time to test the “MinWeigh” function again.

Contact the customer service department of your sales outlet to have a service technician

run the test as soon as possible.

5.3.6 Working with the “MinWeigh” function

The “MinWeigh” function ensures that the weighing results are within a speciﬁed tolerance range in accordance with the requirements

of your quality assurance system. This function must be enabled and programmed by a service technician. The “MinWeigh” function

must be activated in this menu in order to use the function (section 5.2.14). As soon as this function is activated, a small weight icon

containing a “<” appears above the weighing result in the display. We recommend that you also activate the “MinWeigh”, “Ref. Tare”

and “Tare” information ﬁelds (section 5.2.4).
