5 Safety Requirements
Before the first use of the PVPM read this manual carefully and completely. It contains important hints to avoid
damage to persons or the measuring device. These hints are emphasized by a frame around the text and
should be paid attention to.
References in this document, which concern security matters, are indicated by a frame. Damages due to the
neglection of the references in this document are excluded from the warranty. No warranty at all is guaranteed
for consequential damages.
The program
PVPM.disp
requires a PC with hard disk and MS Windows
NT
or higher and a mouse pointing
device. The connection of the PVPM requires a free RS232 serial interface. Please be sure that this interface
has no interrupt conflicts with other devices in the PC.
If no serial interface is available at the PC, the PVPM can be attached to the PC with the help of a commercial
USB to serial converter.
The required free space on the hard disk before installing PVPM.disp is about 5 MB. Please be sure later on
that there is enough free space on the hard disk before storing measured data.
Attention: For the purpose of data security we would like to point out the importance of saving the database
of the program regularly on another data medium, so in the event of damage you will be able to continue
working without considerable data loss. Such a damage can not be excluded even under the present state-
of-the-art. Please do not restore single data files, but always the complete data back-up of the program,
otherwise you might cause malfunction, this in turn might lead to data loss! In case of doubt please contact
the distributor or the producer.
