1.4 General Operating Conditions
The Airflow Monitor and equipment have been designed and tested in accordance with the
safety requirements of the International Electrotechnical Commission (IEC). The Airflow
Monitor conforms to IEC61010-1 (Safety Requirements for electrical equipment for
measurement, control and laboratory use) as it applies to IEC Class 1 (earthed) appliances,
and therefore meets the requirements of EC directive 73/23/EEC.
If possible, avoid any adjustment, maintenance or repair to the eqipment whilst covers are
open or it is operative. However, if any adjustment, maintenance or repair is necessary while
the covers are open, this must be done by a skilled person who is aware of the hazards
involved.
Whenever circumstances arise that mean an Airflow Monitor may be unsafe, make it
inoperative. In particular, an Airflow Monitor may be unsafe if it:
• Shows visible damage.
• Fails to perform correctly.
• Has been subjected to severe transport stresses.
• Has been subjected to prolonged storage in unfavorable conditions.
1.5 Environmental Conditions
The Airflow Monitor should only be used under the following conditions:
• Indoors.
• In ambient temperatures between 41°F and 104°F.
• With relative humidity below 80% for temperatures up to 88°F, decreasing linearly to
50% relative humidity at 104°F.
• Electrical supply fluctuations not exc10% of the nominal voltage.
WARNING
The protection provided by the equipment may be impaired if
the environmental conditions do not lie within these
parameters.
