Important Notes Concerning Measurement Specification Data
The specifications given in these tables al-
ways apply to the physical measuring ranges,
as listed e.g. in the INFO-RANGES.. menu
(parameters „MinRange" and „MaxRange").
All performance data is verified during the manufacturing process for each unit by the following
tests:
• Linearization and sensitivity test
• Long term drift stability test
• Climate chamber test
•
Cross interference test (if applicable)
