Accuracy
- Accuracy1
- Standard accuracy is 0.02% of Reading1. Optional accuracy of 0.015% of Reading is vailable. Calibration certificate with traceability to NIST is provided with each instrument. An optional ISO/IEC 17025 accredited calibration certificate is available.
- Accuracy1
- 1. 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.
