ELECTRICAL CONNECTIONS
LPUVA02…
has a 4-pole connector and uses the
CPM12AA4...
optional
cables.
The metallic housing of the radiometer should preferably be
grounded ( ) locally. In this case, do not connect the wire of the
cable corresponding to the housing to prevent ground loops.
Only if it is not possible to ground locally the metallic case of the
radiometer, connect the wire of the cable corresponding to the
housing to ground.
Note: in LPUVA02AV the housing is not connected
to the connector.

LPUVA02
CONNECTIONS
The radiometer LPUVA02 is
passive
and does not require power supply. It is to be
connected either to a millivoltmeter or to a data acquisition system. Typically, the ra-
diometer output signal does not exceed 50 mV. In order to better exploit the radiome-
ter features, the readout instrument should have 1
µ
V resolution.
