Specifications are valid under the following conditions: The instrument is within the calibration period, has been stored between 0 and 50°C for at least 2 hours prior to use, and has been powered
on and warmed up for at least 40 minutes. The specifications include the measurement uncertainty, unless otherwise noted.
Specifications: All products are guaranteed to meet published specifications when operating temperatures from 5 to 45°C, unless otherwise noted.
Typical: Performance deemed typical implies that 80 percent of the measurement results will meet the typical published performance with a 95th percentile confidence level at room temperature
(approximately 25°C). Typical performance is not warranted and does not include measurement uncertainty.
Nominal: The expected performance or design attribute.
