1. Safety instructions

The connector box conforms to all safety regula­tions for electrical measuring, control, monitoring
and laboratory equipment, as specified under
DIN EN 61010, Section 1. It is intended for opera­tion in a dry environment, suitable for the opera­tion of electrical equipment and systems.

Safe operation of the equipment is guaranteed,
provided it is used correctly. However, there is
no guarantee of safety if the equipment is used
in an improper or careless manner.

If it may be assumed for any reason that non­hazardous operation will not be possible (e.g.
visible damage), the equipment should be
switched off immediately and secured against
any unintended use.

• Only use this equipment in dry rooms.

• Do not apply any external voltage to the

output sockets (2 + 3).

• Only use with the supplied plug-in power

supply

2. Description

The connector is designed to connect the photo
gate (1000563) or laser reflection sensor
(1001034) to digital counters equipped not with
8-pin miniDIN sockets but with 4-mm-input
sockets.

When used with the photo gate (1000563) or
laser reflection sensor, the counter should be
connected to the connector box with the black

1

socket wired to Output 2 (ground) and the red
socket to Output 1, i.e. crossed over.

Apart from the two digital sensors already men­tioned, it is also possible to connect other ana­logue sensor boxes, such as magnetic field sen­sors (1000558 or 1009941) or the barometer
(1000549), with the values they measure being
recorded via peripheral devices. The measure­ments are then output in the form of an ana­logue voltage at Analogue output 1 via the blue
and red sockets. Analogue output 2 is intended
for sensor boxes which detect two measure­ments at once, such as the blood pressure sen­sor (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.

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 dis­posed of at local recy­cling centres.

• Sensors such as the photo gate or laser

reflection sensor are connected to the con­nector 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.
