.1 Front
The four sensors are
labeled
Sensor 1 - 4. First the power supply must be connected. When a
sensor is connected, the corresponding power LED is activated.
The Link-LED is only activated
when a PC/Laptop connection via the USB socket on the back exists. If the Link-LED is dark, check
the
SI-USB4
connection to the PC/Laptop. Temperature measurements are possible at sensor con-
nection 1 and/or sensor connection 4.

.2 Back
In addition to the serial number in the first field, the sensors and their associated connections are
listed here in the second field.
It is important to ensure that there is no interchanging of the sensors, e. g. if a measuring
chain exists.
The power is supplied either via the black power supply socket with a separately delivered power sup-
ply unit or via the green socket. Again, the polarity is independent for both power supply sockets. The
middle PIN is the shield for the green socket.
