Technical Specifications
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.
