Safety
2.2.1 Environmental conditions
FDM-T Measuring Systems are suitable for application in dry interiors with level ground
such as those in hospitals, doctors' surgeries and laboratories.
Temperature range
10°C to 40°C
Relative humidity
30% to 70%
WARNING
FDM-T systems must NOT be operated in wet zones, wet rooms
(swimming pools, saunas) or climatic chambers.
Direct contact with liquids must always be avoided, as the measur-
ing system is not protected against the entering of liquids. Liquids
entering the device can cause fire, electrical shock or other severe
accidents.
The FDM-T system is NOT specified for the operation in vacuum,
hyperbaric or altitude chambers.
The measuring systems are not intended for operation in potentially
explosive atmospheres of medically used rooms or oxygen-enriched
atmospheres.
The devices must not be operated in proximity to e.g. engines or
transformers with a high connected load as well as mains current
lines, as electrical or magnetic interference fields can falsify correct
measurements resp. turn them impossible. Therefore, the devices
have to be protected against humidity. The ventilation slots of the
treadmills must be free at all times, so that air can circulate freely.
2.2.2 Storage and Transport
Storage and transport of the measuring system are only to be effected in the original
packaging provided by zebris.
Storage temperature
-20°C to +70°C
Relative humidity
5% to 90%
Air pressure
700 hPa to 1060 hPa
NOTE
All FDM-T systems can be stored without power supply for a maxi-
mum of 6 to 9 months. After this period, the battery may be totally
discharged due to lacking power supply. If the storage of the device
exceeds this period, a re-programming of the treadmill control may
be necessary.
