1. Total uncertainty, % of full span for temperature range 0°C to +50°C, one year interval. Total uncertainty,
1.0% of full span for temperature range -10°C to 0°C, one year interval. No 6 month specification available for range -10°C to 0°C.
2. "Non-corrosive gasses" indicates dry air or non-corrosive gas as compatible media. "Stainless Steel 316-SS"
indicates media compatible with Type 316 Stainless Steel.
3. Specifications % of Full Span unless otherwise noted.
4. Reference Uncertainty is the specification for as left data for 24 hours.
5. When reference class modules are used with fixed resolution products (717, 718, 719 series, 725 and 726)
calibrators add ±1 count to the overall accuracy specification.
6. Burst rating specification refers to the multiplier times full scale of the module for the rated burst
pressure. |
