| Accuracy | |
| Accuracy* | Standard accuracy is 0.02% of Reading*. Optional accuracy of 0.015% of Reading is available. ISO/IEC 17025 accredited calibration is provided with each instrument. *Accuracy is based on % of Reading from 10% to 100% of the piston range when used in accordance with the corrections found on the calibration certificate. Below 10%, ± (accuracy class) x 10% of the piston range. See the “Guide for the Uncertainty Analysis in Pressure when Using P3000 Series Deadweight Testers” technical note for more information. |
