The “Statistics” application

6.4 Working with the “Statistics” application

This section describes how to work with the “Statistics” application. You can of course determine a tare, change the resolution of the

weighing result, work with IDs, etc.

These options were already described in the “Weighing” application (section 5.3) and are therefore not repeated here.

6.4.1 Statistical acquisition of series weighing values

Presettings

The minimum requirement for using the statistics (section 6.3.2) is that the 3 function

keys opposite must be activated.

In addition, we recommend that you activate both of the function keys opposite. They are

used to delete incorrect values (“CL Last”) and to deﬁne the number of samples to be

included in a weighing series (“Max n”).

A printer should be connected to your balance for optimum use of the statistical functions.

If no printer is connected, we recommend that you activate the four main information ﬁelds

for the statistics for your application (e.g. “n”, “x”, “s” and “Sum”, see section 6.3.3).

Note: If at the start of a series weighing you use a “free weighing unit” (section 5.2.7),

the weight unit can only be changed back again after the measurement series has been

completed.

Operating sequence

If the number of samples to be weighed in for a series is speciﬁed in advance, you can

press the “Max n” function key and enter the number of samples (1...999). After the last

sample is weighed in, the series is automatically closed, the statistics window is opened

and the printed results record is printed. Note: This function key is only active when the

statistics do not yet contain any measured values. Enter the value 0 (zero) for “Max n” to

set an unlimited series where you can weigh in up to 999 samples.

If you are working with a weighing container, place it on the pan and press the «H»

key to tare the balance (alternatively you can also work with the tare memories or use

the automatic tare function; these functions are described for the “Weighing” application

in section 5).

Place the ﬁrst sample on the pan and press the “M+” function key to transfer the weight to

the statistics. As soon as the weight value becomes stable (horizontal dashes disappear),

the value is transferred to the statistics. The report header is printed out together with the

result (single value) of the current weighing operation (section 6.3.5).

Lift off the ﬁrst sample. Note: If Additive Weighing has been activated (section 6.3.6), you

can leave the sample on the weighing pan, as the balance is tared automatically every

time a weight value is transferred to the statistics.

Place the other samples on the pan one after the other. Conﬁrm each weighing with the

“M+” function key (not necessary when weight transfer is activated, see section 6.3.4).

Lift the sample off and tare the balance (not necessary when additive mode is activated,

see section 6.3.6). Each time a value is transferred to the statistics, it is printed automati-

cally.
