1 Notes
Development:
The BATLOGGER was developed in a cooperation of the Swiss Federal Research
Institute
WSL
and the University of Applied Sciences Northwestern Switzerland FHNW, with financial help
from the Environmental Research of the Swiss Federal Office for the Environment FOEN.
Environmental conditions:
The BATLOGGER is housed in a robust synthetic case for measuring
devices, ant it is operated through a polyester foil keyboard. With the many openings for GPS,
microphone, memory card, charging plug etc., it does only reach imperviousness level IP 30 and
therefore is not protected against water. When used in the field, unobserved and for extended periods of
time, the logger should be stowed in a waterproof box (Strongbox Part # 212.006) or bag, with the
microphone externally connected through a cable.
Microphone / ultrasound sensor:
An active electret microphone is used as plug-in ultrasound sensor.
Attention has to be payed to a proper fitting of the microphone in its plug. The microphone itself can be
damaged by water. It must be protected from rain and extreme humidity, and it requires corresponding
positioning. For special recording purposes, the microphone can be connected with the logger through a
shielded stereo audio cable of no more than 2 m length.
Speaker
A
:
The speaker can also be used for monitoring during recording. Depending on environment
and volume this may lead to acoustic feedback (loud whistling). In this case, reduce the volume and hold
the BATLOGGER further away from reflecting objects such as walls or your own body or use
headphones.
Li-Ion battery:
The internal power is provided by a lithium-ion battery of 3,6 V and 4600 mAh. When
transporting and storing several BATLOGGERs together, the corresponding regulations have to be
followed.
Storage media SD / SDHC – card:
The BATLOGGER uses SD / SDHC cards of up to 32 GB capacity
as storage media. Test have shown, that cards of different vendors may vary in writing and erasing
speed. We refrain from giving recommendations for specific products or vendors, as offered sizes and
technologies change constantly, which may also influence card performance.
Legende for display illustrations:
On the following pages the operation of the BATLOGGER is explained using symbolic representations of
the LCD display. The illustrations are only for the sake of clarity and understanding, and do not
necessarily reflect what you see on the device.
