1. Predicted Q-RPT measurement stability limit (k=2) over one year assuming regular use
of AutoZero function. AutoZero is performed by the operator: against zero pressure
when vented in gauge mode, by direct comparison of one Q-RPT to the other at
the line pressure in differential mode, by comparison with a barometric reference in
absolute mode. Absolute mode predicted one year stability without AutoZ
is ± (0.005 % Q-RPT span + 0.005 % of reading).

Measurement
Uncertainty3:
2. Combined linearity, hysteresis, repeatability. Add + 1 Pa (0.00015 psi) in gauge mode
for the resolution and short term stability of the on-board barometer.
3. Maximum deviation of the Q-RPT indication from the true value of applied pressure
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.”
