Operating temperature15 °C to 35 °C (59 °F to 95 °F)
Warm up time30 minute temperature stabilization recommended from cold power up
VibrationMeets 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.”
