| 1. Precision: Combined linearity, hysteresis, repeatability. 2. Stability: Maximum change in zero and span over specified time period for typical molbox and molbloc used under typical conditions. As stability can only be predicted, stability for a specific molbox and molbloc should be established from experience. 3. Measurement uncertainty: Maximum deviation of the molbox2 flow indication from the true value of the flow through the molbloc including precision, stability and Fluke calibration. 4. With regular use of Autozero. Add 0.005 % of Q-RPT span for one year without use of AutoZero, (translates to 0.005 % FS for molbloc-S, does not significantly affect molbloc-S standard calibration or molbloc-L uncertainty.) 5.
