System Specifications
These specifications describe the system’s warranted
performance and apply after a 30 minute warm-up.
These specifications are valid over its operating
and environmental range, unless otherwise stated.
Supplemental Characteristics (shown in italics)
These are intended to provide additional information, useful in applying the instrument by giving
typical (expected), but not warranted, performance
parameters. These characteristics are shown in
italics or labeled as “typical,” “usable to,” or “nominal.”
NOTE: The following specifications are only applicable to firmware revision C.01.00 onwards.
