| Warm up time | 30 minute temperature stabilization recommended from cold power up | |
| Vibration | Meets MIL-T-28800D | |
| Predicted Stability1 | ± 0.005 % of reading | ± 0.0032 % of reading |
| Precision2 | ± 0.008 % of reading | ± 0.006 % of reading |
| Measurement Uncertainty3 | ± 0.01 % of reading | ± 0.008 % of reading |
| 1Predicted Q-RPT measurement stability limit (k=2) over one year assuming regular use of AutoZero function. AutoZero is performed by the operator by comparison with a barometric reference in absol mode. Absolute mode predicted one year stability without AutoZ is: Single Channel ± (5 Pa + 0.005 % of reading), D Channel ± (4 Pa + 0.0032 % of reading). 2Combined linearity, hysteresis, repeatability. 3Maximum deviation of the Q-RPT indication from the true value of applied spressure including precision, predicted one year stability limit, temperature effect and calibration uncertainty, combined and expanded (k=2) following the ISO “Guide to the Expression of Uncertainty in Measurement.” | ||
