Continuous measurement
This function allows the automatically timed measurement
controlled from the PC.
Set the desired time interval and the time unit (seconds,
minutes, hours) for the execution of the measurement and
the number of repetitions (0, if measurements shell be
repeated infinite).
After pushing the button “Start measurement” the
measurement runs automatically and can be cancelled by
the “Stop” button. The measured data will automatically
stored to files in the predefined directory. The file names
contain the date and time of the measurement.
The automatic measurement will stop, when the given
number of repetitions are finished or when the PVPM does
not answer.

Settings
All changes made here will be saved automatically and are valid until the
next change.
12.3.7.1 Serial Port
You can select the serial RS232 port (COMn:) used for PVPM
communications from the combo box
If the application can read the list of existing serial interfaces from the Windows registry, the identifiers of the
interfaces defined there are represented in the combobox - together with the
reference whether this interface is available or not. In the latter case this
interface is already occupied by another application. If the registry cannot be
read (insufficient user rights), the application will only display simple interface
identifiers like „COMx“. A selection of the interface is possible anyway. If you
do not know, to which interface the PVPM is attached, you can use the
button „look for“: that allows the application to automatically try all available
interfaces in order to establish the communication with the PVPM. The PVPM
must be attached to the PC and set to „transfer“. If the application receives
an valid answer from a PVPM, the search stops and the detected interface is
used now for communication with the PVPM.
12.3.7.2 Working directory
The working directory is used in file open and file save dialogs and for the automatically saving of files. Select
here the directory which contains your measured data or to which the measured data should be saved to. This
listing is used also during the automatic data storage (data transfer of PVPM or continuous measurement) The
entry field has a button at its right side. Press this button to display a directory selection dialog.
12.3.7.3 Dialogue language
PVPM.disp supports the dialog languages English and German. The language can be changed during program
execution. Just select your desired language from the combobox “dialog language”. After you close the dialog
