Specifying the computation method for blank value and daily factor
Defining the blank value calculation method
Proceed as follows:

Open the "Configure Calculations" dialog in the operating software by selecting
Options >
Settings > Calculation
.

In section "Blank value determination" define the calculation method:
If you...

... select "sequentially" a separate blank value is computed for every element in every group
of blank value samples; this value is entered in the respective blank value column until the
next group of blank value samples.

... select "entirely" all blank value samples in the series are used to compute the blank
value. This blank value is then applied to all samples in the series.

... select "manual input" blank value calculation is not performed - even if there are blank
samples in the series. This allows manual input of blank values for individual samples.

... "autom. activate "automatic blank value calculation" the blank value is automatically
computed at the end of every analysis. This option ist not available if manual input has
been checked.

Then click
OK
to save your settings.
Defining the daily factor calculation method
Proceed as follows:

Open the "Configure Calculations" dialog in the operating software by selecting
Options >
Settings > Calculation
.

In section "Factor determination" define the calculation method:
If you...

... select "sequentially" then the daily factor is computed group-by-group and changes
throughout the day.

... select "entirely" the daily factor is computed on the basis of all factor samples in the file.
An average factor is computed.

... select "manual input" factor calculation is not performed - even if there are factor samples
in the series. This allows manual input of daily factors for individual samples.

... "autom. activate "automatic factor calculation" the factor is automatically computed at the
end of every analysis. This option ist not available if manual input has been checked.

... activate "upper/lower calib. range distinction" both for the upper and lower calibration
range separate factors will be calculated. This requires separate factor samples for each
range.

Then click
OK
to save your settings.
Enabling/disabling acoustic signals
Enabling/disabling acoustic signals
Proceed as follows:

Open the "Acoustic signals" dialog by selecting
Options > Settings > Acoustic Signals
.

Decide:
If you want to...

... switch on a signal, check the appropriate checkbox.
