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 informa-
tion, 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 applica-
ble to firmware revision C.01.00 onwards.
