Operating conditions
The instruments are destined for use in dry clean rooms. Ope-
ration in an environment with high dust content, high humidity,
danger of explosion or chemical vapors is prohibited.
Operating temperature is 0 .. +40 degrees C. Storage or trans-
port limits are –10 .. +70 degrees C. In case of condensation
two hours are to be allowed for drying prior to operation.
For safety reasons operation is only allowed from 3 terminal
connectors with a safety ground connection or via isolation
transformers of class 2. The instrument may be used in any
position, however, sufficient ventilation must be assured as
convection cooling is used. For continuous operation prefer a
horizontal or slightly upward position using the feet.
Do not cover either the holes of the case nor the
cooling fins.
Nominal specs are valid after a warm-up period of min. 20
min. in the interval of +15 to +30 degrees C. Values without a
tolerance are typical of an average production instrument.
