Activity measurements via infrared sensors (InfraMot)
•
Infrared sensors supplied by TSE should be used only.
•
There should be no external heat source in the measuring area of the sensor - and no persons
should stand directly in front of the cage.
Activity measurements via voluntary running wheels
•
The voluntary running wheels are designed for measuring the spontaneous wheel activity of
small laboratory animals only.
Improper Use
2.5.2.
•
No constructional alterations should be made to the system without the explicit written
authorization of the manufacturer.
•
The system must NOT be used…
o
…in an explosive environment.
o
…with dirty and contaminated device components. Do NOT store the system when it is
still contaminated.
•
Do NOT obstruct any ventilation openings.
Computer system (PC, PC monitor, Process Control Units, etc.)
•
Only those programs described in the instructions should be installed on the PC in order to
rule out software incompatibility.
•
Windows internal programs and memory resident software should be deactivated, e.g.,
screensaver, automatic switch OFF, etc.
Animal cages
The animal cages should be assembled and connected as described in these instructions only, as
otherwise inaccurate results will be obtained.
If calorimetry measurements are to be made without the presence of the drinking dispensers / feeding
dispensers, the corresponding openings should be closed off.
Sensors
•
The sensors are intended to register the specified measured values only and are to be used
for this purpose only. For proper use, the calorimetry and the drinking & feeding & body weight
sensors should be calibrated.
•
The drinking and feeding sensors must always be handled carefully. Do NOT drop them.
When not in use, they should be stored in transport boxes.
•
The infrared sensors for measuring the activity should be free from contamination, and the
path should NOT be hindered by solid objects in the vicinity of the sensors.
Calorimetry measurements
•
Air supply pumps (push principle respirometry, overpressure principle)
o
The air supply pump supplied must be used for generating the required air flow only.
Oil-operated compressed air generators will destroy the sensitive measuring and
control equipment.
o
The pump must NOT be installed in area that is subject to explosion hazard.
o
The following media must NOT be allowed to enter the air intake: dangerous gas
mixtures (e.g. combustible gases, explosive gases or vapors), extremely humid air,
water vapour, any liquids, aggressive gases, oil traces or oil mist, and grease.
