3.2 Environmental Conditions
Although the instrument has been designed for optimum durability and trou-
ble-free operation, it must be handled with care. The instrument should not be
operated in an excessively dusty or dirty environment. Maintenance and clean-
ing recommendations can be found in the Maintenance section of this manual.
The instrument operates safely under the following conditions:
• temperature range: 5-40°C (41-104°F)
• ambient relative humidity: maximum 80% for temperature <31°C, de-
creasing linearly to 50% at 40°C
• pressure: 75kPa-106kPa
• mains voltage within ±10% of nominal
• vibrations in the calibration environment should be minimized
• altitude less than 2,000 meters
