The battery box (power supply) is used with
microphones and other sensors which require an
operating voltage and where the signal is fed to
equipment that doesn’t provide it, e.g. an
oscilloscope, multimeter or older counter.
The power supply is provided with an internal 9
block battery and with a 3.5 mm jack connector for
a main adapter.
Required accessories:
9 battery (6 LR61) – included. A mains adaptor
can be used instead. (3,5 mm jack, tip positive).

Operation
Microphone to oscilloscope
Microphone 248600 with cable 248601
Microphone 248510
If it is desired that the sound signal from a
microphone be connected to an oscilloscope the
microphone 6-pin DIN plug is inserted in the DIN
connector marked “Mic 2". Using a shielded cable
with 4 mm safety plugs at one end and a BNC
plug in the other, connect the battery box to the
oscilloscope.
Microphone 248600 with cable 248602
Microphone probe 251550
The procedure is the same when using these
microphones, but in this case the microphone
should be connected to the 5/8-pin DIN connector
marked “Sensor”.
Sensors
Many sensors from Frederiksen, Pasco and
ernier use 5-pin DIN plugs and require a 5 DC
supply voltage. (For example: IR sensor, broad-
band 287281). These should be connected to
the 5/8-pin DIN connector marked “Sensor”, and
the signal can be sent to a multimeter or other
read out unit using the 4 mm safety connectors.
