Specifications
Specifications describe the instrument’s warranted performance over the temperature range of 0 °C to 40 °C (except as noted). Supplemental performance
characteristics are intended to provide information that is useful in applying
the instrument by given 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.
