Specifications

Specifications describe the instrument’s warranted performance over the temperature range of 5 °C to 40 °C (except as noted). Supplemental performance characteristics are intended to provide helpful information for using certain non-warranted performance parameters with the instrument. These are denoted as SPC (supplemental performance characteristics), typical, or nominal. Warmup time must be greater than or equal to 30 minutes after power on for all specifications.
