Recommendations for operation and maintenance
Datalogger operation in several application areas
________
Before putting the device into operation, it should be considered, if its
usage is suitable for the intended purpose. In connection with this
consideration the device‘s optimum settings should be determined.
In the case that the device is part of a larger measurement system,
instructions for its metrological and operational checks should be
developed
Inadvisable or hazardous applications:
This datalogger is not intended for such applications in which the failure
of its functioning could directly endanger life and health of humans
and animals, or the functioning of other equipment with life-sustaining
functions. In applications the failure or malfunction of which could result
in severe property damage it is recommended to provide the system
with suitable and independent signalling equipment which is able to
evaluate such a condition and, in case of failure, to prevent the above
mentioned damages (See the chapter „
).
Device positioning:
Adhere to principles and procedures mentioned in this manual. Try to
choose such a place to position the device, where the negative
influence caused by environment is as low as possible. When
performing measurements in refrigerators, metal boxes, metal
chambers and the like, it is every time advisable, as far as the device’s
operation and reliability is concerned, to place the device outside,
leaving only the sensors and probes inside the measured environment.
Positioning of temperature sensors:
These sensors should be placed in locations where sufficient air
circulation is ensured and where the most critical location is supposed
(according to the application requirements). To prevent heat
conduction through the sensor cables from undesirable influencing
the measurement value, the sensor must be properly inserted into
the measured environment.
If you follow the temperature distribution
in an air-conditioned storehouse, do not place the sensor into the direct
air stream generated by the air-conditioning unit. As a matter of fact,
the temperature distribution in large-chamber refrigerators may be
quite inhomogeneous, the temperature differences reaching up
to
10°C. Similar dispersion can be found inside deep-freezing boxes
(e.g. in those used for blood preservation by deep freezing).
