Battery; Ac/Dc Adaptor - Fourier TriLink User Manual

1. Sensor input (In) sockets marked In-1/8 In-2/7 In-3/6 and In-4/5: These sockets
are used to connect the sensors. Normally, all four sockets can be used
simultaneously.
To connect a sensor to the TriLink use one of the sensor cables. Plug the
stereo plug into the data logger, and the mini-din plug into the sensor -
arrow facing down.
In order to connect more than 4 sensors at a time, use the splitter cables, which
will enable the connection of up to 8 sensors simultaneously. When a splitter
cable is connected, it must be connected to the socket in the correct numerical
order (e.g. for 5 sensors, connect the splitter cable to In-4/5). One of the two
splitter cables is marked with P1 - that is the main input (the lower input number),
the second line is marked with P2 - indicating that it is the secondary input (the
higher input number). Connect up to four input splitters (DT225) to split the
TriLink's inputs starting with In-4 (the splitters must be connected in order):
In-4 splits into In-4 and In-5
In-3 splits into In-3 and In-6
In-2 splits into In-2 and In-7
In-1 splits into In-1 and In-8
2. PC USB communication socket: Connect the mini USB plug of the USB
communication cable to the TriLink and the USB Type A plug to the computer's
USB port (see page 75 for USB driver installation).
3. External DC power supply socket: Plug in an AC/DC 9 - 12V adaptor whenever
you want to save battery power, or to charge the battery when necessary.
Connecting external power to the TriLink automatically charges the internal
battery. The adaptor should meet the required specifications (see section
1.1.4).

Battery

TriLink is equipped with a 2.4V/750mAh NiMH rechargeable battery. Before you start
working with TriLink for the first time, charge the unit for 10 to 12 hours while it is
turned off.
The battery lifetime is about 8 hours of continuous work.
If the data logger's main battery runs out, the internal 3V Lithium battery backs up
the memory, so no data will be lost.
Note: Battery shelf charge life is about 100 hours. To maximize battery
shelf charge life, always disconnect sensors when not in use.
Disconnect TriLink from the computer when not in use. You can
continue to operate TriLink by plugging it into the wall.
