5.6.1CO, CO, FIC calibration
For single-stage calibration, first use the first group of standard gases for calibration and then separately introduce the other three groups of working gases for indication error verification. For measuring instruments, three points should be marked within the maximum intensity range and then one point should be selected within the test range for verification. The key points should be measured three times and the arithmetic mean should be taken. The indication error is calculated by the following formula: C = C -
Where:
is the average value of a single reading,
is the standard gas concentration value)
is the absolute error,
is the relative error.
This should comply with the provisions of Table 2 in 4.4. 5.6.20 Channel calibration: After the instrument is calibrated at 0°C, 100°C and 200°C of standard gas are respectively introduced. Each point is measured three times and the arithmetic mean is taken. The error of indication is calculated according to formula (7) and (8). It shall comply with the provisions of 4.4.2. 5. Determination of single error: After the instrument is stabilised by air, other groups of standard gases are introduced and the value is obtained. Without adjusting the measuring point and the measuring point, the error is measured six times and the average value is taken. The repeatability error is expressed as the relative standard error, that is, 2°C. Assume that the relative standard error is: It shall comply with the provisions of 4.5.
