Technical Specifications
January 2007
Specification: describes a guaranteed product performance that is valid under the specified conditions. Specifications are
based on a coverage factor of 2 (unless otherwise stated), corresponding to a level of confidence of >95%.
Typical value: a characteristic, describes the product performance that is usually met but not guaranteed.
Generally, specifications are valid after warm-up, after zeroing, in auto-range mode (if not differently stated) and at the
stated operating conditions and measurement settings.
