251560 manual eng. - Frederiksen

Power Supply no. 2515.60
07.05.12 Ae 2515.60
The power supply is used with microphones and
other sensors which require a 5 VDC operating voltage
and where the signal is to be output to an external
measuring device, e.g. an oscilloscope, multimeter
or counter. The power supply is provided with an
internal 9 V block battery and with a 3.5 mm jack
connector for using an adapter.
Required accessories:
9 V battery (6 LR61) – included. A mains adaptor can
be used instead. (9V, 3,5 mm jack, tip positive).
Important!
This apparatus is battery operated. The bat -
tery supplied with it is wrapped in insulating
cellophane and placed in the battery holder.
Unwrap the battery and place it in the holder
before operation.

Operation:
When connecting microphones (type 2485.10) to
older counter/timer units (type 2000.XX and
2001.XX), use the DIN connectors marked “Mic 1"
and “Mic 2". The two 5 pole DIN output connectors
can be connected to the DIN connectors on the
counter/timer using cable type 1122.20 (parallel
cable with DIN jacks). NB: Certain older model counter/timers
have only room for 3 pins in the DIN connectors.
In these cases the easiest solution to break
off the two surplus DIN jack pins at each end of the
1122.20 cable.
Microphone 2485.10 to the Pasco interface:
Because of the pin connections on the unit the
mi crophone type 2485.10 can not be connected
directly to the Pasco interface. Instead connect the
microphone to the power supply, and use the
1122.20 parallel cable to connect the microphone
output signal to the Pasco Science Workshop interface.
The parallel cable should be connected in this
case to the DIN connector marked “Sensor” on the
power supply.
Microphone to oscilloscope:
Microphone no 2485.10:
If it is desired that the sound signal from a microphone
be connected to an oscilloscope the type
2485.10 microphone DIN jack is inserted in the DIN
connector marked “Mic 2". Using a shielded cable
with 4 mm safety jacks at one end and a BNC jack in
the other connect the battery box to the oscillo -
scope.
Microphone prope rod no. 2515.50:
The procedure is the same when using microphone
probe rod no. 2515.50, but in this case the microphone
should be connected to the DIN connector
marked “Sensor”.
Sensors:
Many sensors from Pasco and Vernier use 5-pole
DIN jacks and require a 5 VDC supply voltage. For
example: UVA (2872.00), UVB (2872.61), IR (2872.81)
and LUX (2872.51). These should be connected to
the DIN connector marked “Sensor”, and the signal
can be sent to a multimeter or other read out unit
using the 4 mm safety jack connectors.
