Measurement error. The analyser shall not deviate from the nominal calibration point by more than ±2 per cent of the reading or ±0.3 per cent of full scale, whichever is larger.
Measurement error. The difference between sample values and in situ “true” values associated with the measurement process. Measurement error includes bias and imprecision associated with sampling methodology, specification of the sampling unit, sample handling, storage, preservation, identification, instrumentation, and the like. The data requirements for this project encompass aspects of laboratory analysis and database management to reduce sources of errors and uncertainty in the use of the data.
Measurement error. The total measurement error, including the cross sensitivity to other gases - see Annex 4, Appendix 2, paragraph 1.9. shall not exceed ± 5 per cent of the reading or 3.5 per cent of full scale, whichever is smaller. For concentrations of less than 100 ppm the measurement error shall not exceed ± 4 ppm.
Measurement error. If at any time any of the measuring or testing equipment is found to be out of service or registering inaccurately in any percentage, it shall be adjusted to read accurately, within the limits prescribed by the manufacturer. If at any time any of the measuring or testing equipment used for custody transfer is out of service or inaccurate by an amount exceeding two percent (2%) at a reading corresponding to the average rate of flow for the period since the last preceding test, the previous readings of such equipment shall be disregarded for any period definitely known or agreed upon, or for a period of one-half of the time elapsed since the last test of the measuring equipment affected, not to exceed fifteen (15) Days. The volume measured during such period shall be estimated by (a) using the data recorded by any check measuring equipment if installed and registering accurately, or if not installed or not registering accurately, (b) by correcting the error if the percentage of error is ascertainable by calibration, test, or mathematical calculation, or if neither (a) or (b) is feasible, (c) by estimating the quantity or quality measured, based upon deliveries under similar conditions during a period when the equipment was registering accurately. No correction shall be made for recorded inaccuracies of two percent (2%) or less.
Measurement error. If a Party is aware that the measurement of an electric quantity measuring device is inaccurate, or occurs breakdown, it shall promptly notify the other Party. The Parties shall consult each other and find a solution as soon as possible. The Parties may determine the electric quantity of the period of breakdown or inaccurate measurement according to any reference data. If there is no sufficient basis to determine the electric quantity occurred during the period of breakdown or inaccurate measurement, it shall be separately determined by the Parties through consultations.
