1. Combined linearity, hysteresis, and repeatability. Precision does not include stability or calibration reference uncertainty.
2. Predicted Q-RPT measurement stability limit (k=2) assuming regular use of AutoZero function and short term stability between rezeroing.
3. Maximum deviation of the Q-RPT indication from the true value of applied pressure including precision, predicted stability with rezeroing, temperature effect from 10 ºC to 40 ºC and calibration uncertainty (assumes calibration reference uncertainty of ± 0.005 % of reading, k=2), combined and expanded (k=2) following the ISO “Guide to the Expression of Uncertainty in Measurement”. |
