How can the rapid sulphur meter be not calibrated? How to use standard coal sample to calibrate a microcomputer rapid sulphur meter? The rapid sulfur measuring instrument is the most common analytical instrument in the coal quality laboratory. It is specially used to measure the sulfur content in coal. Do the low calorific value of coal in power, need to enter the amount of sulfur based analysis can make the measured accurate results, so the accuracy of sulfur measuring instrument has a very high demand, need to obtain very accurate results. Hebi Huanuo coal analyzer factory has rich technical experience in coal laboratory equipment industry, micro sulfur measuring instrument in the process of using if improper maintenance, or other causes of the low sulfur tester or instability is a common thing, when the result is not stable or maintenance after the need for sulfur instrument calibration.
1, first do 2~5 waste sample. Because it is the calibration, try to do as many as possible to ensure the optimum state of the system. The sulfur content of the waste sample is close to the standard coal sample.
2, three of the three kinds of standard coal samples were selected for low, medium and high standard. If the measured results are in the permissible error, the average value is taken.
3, the standard coal samples with low sulfur 0.50, for example, three times the average value is 0.46. The N in the coefficient is 0.04, meaning adding 0.04. For example, the average value of the three results is 0.55. Adjusting the system parameter n into 1.05 means subtracting 0.05 (of which 0 is added, 1 is subtracted)
4. The u in the parameters of the medium high sulfur modulation system is also 0, and 1 is a reduction.
The maximum adjustment of u and N 0.09 means adding or subtracting 0.09 of the test results of the sulfur fixing instrument. In addition to adjusting the high sulfur coefficient of u and the low sulfur coefficient of N, the coefficient of L=1.000 height adjustment of the system can be adjusted and the result is raised, while the decrease of the whole coefficient is reduced. The overall coefficient adjustment range is between 0.900 and 1.100.
Each adjustment coefficient can be observed after the change of the key "3".
