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: 5–45°C (41–113°F)
• ambient relative humidity: 15 - 50%
• pressure: 75kPa - 106kPa
• mains voltage within ± 10% of nominal
• vibrations in the calibration environment should be minimized
• altitude less than 2,000 meters
