Installation & Operating Manual
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 5°C and 40°C.
• With relative humidity below 80% for temperatures up to 31°C, decreasing linearly
to 50% relative humidity at 40°C.
• Electrical supply fluctuations not exc10% of the nominal voltage.
