Data Sheet
Specifications describe the instrument’s warranted performance over
the temperature range of 0 °C to 40 °C (except as noted). Supplemental
characteristics are intended to provide information that is useful in applying
the instrument by giving non-warranted performance parameters. These are
denoted as SPC (supplemental performance characteristics), typical, or
nominal. Warm up time must be greater than or equal to 30 minutes after
power on for all specifications.
