socket wired to Output 2 (ground) and the red
socket to Output 1, i.e. crossed over.
Apart from the two digital sensors already men-
tioned, it is also possible to connect other ana-
logue sensor boxes, such as magnetic field sen-
sors (1000558 or 1009941) or the barometer
(1000549), with the values they measure being
recorded via peripheral devices. The measure-
ments are then output in the form of an ana-
logue voltage at Analogue output 1 via the blue
and red sockets. Analogue output 2 is intended
for sensor boxes which detect two measure-
ments at once, such as the blood pressure sen-
sor (1000578). In that case, the Korotkov signal
can be read from Output 2.
When connecting analogue sensor boxes, it
should be noted that the output voltage is not
calibrated and there is no automatic matching of
measurement curves.

5. Operation
• Sensors such as the photo gate or laser
reflection sensor are connected to the con-
nector box via miniDIN cables.
• Use the plug-in power supply to supply
power to the connector box.
• Connect the counter to the black socket
(ground) of Output 2 and the red socket of
Output 1 via experiment leads.

7. Disposal
Should the equipment need
to be scrapped, it must not
be disposed of in normal
household waste.
• Packaging and compo-
nents should be dis-
posed of at local recy-
cling centres.
