6.3 Operating instructions "OV-DMPC"
The operating instructions can be selected from any
page of the "OV-DMPC" measuring programme via the
?
help symbol ? .
ATTENTION
Read the operating instructions in their entirety be-
fore connecting the "DMPC - sensor".
6.4 Connection of the "DMPC-sensor"
The "DMPC-sensor" is connected to the USB slot (2.0)
of the computer via the enclosed USB cable. Further
advice regarding the operation of the "DMPC-sensor"
is detailed in the operating instructions. It can be se-
lected from any page of the "OV-DMPC" measuring sys-
tem via the help symbol ? .
The following advice must be observed when connecting
the "OV-DMPC" to central heating or cooling systems.
NOTE
Provide free water flow through measuring
hoses. Should the strainers of the "DMPC-sensor"
be heavily polluted, they have to be cleaned or re-
placed.
After installation, check all installation points for leaks.

7 Maintenance
