Using computer on the bridge, resistance box test data processing
At the same time the number of sub-degree online, note the galvanometer position of the cursor (ie, caused by the thermocouple to generate electric potential deflection) followed. Then converted to DC power supply,[link widoczny dla zalogowanych], adjust the galvanometer refers to the exchange value of the cursor location, thus completing the measurement of the exchange. The amount of leakage current point, watch and rolling, very otter Verification Of particular note next screen. This is because the test microammeter, the standard resistor. Often choose a larger value (to ~ l0o). At this point, if ~ small leakage current will result in a larger test error. Can be seen from the figure, c cable between two points outside of the points generated by the standard resistance leakage current month. And the impact of instrumentation were the same, will not affect the accuracy of detection. Produced only b points Aj can cause leakage current test error. As shown in the figure plus one other potential screening system can ensure the flow through the standard resistance and was seized on the same sheet of current. The figure by adjusting the auxiliary branch of the month: so that potential 6 points and 6 are equal. Thus ensuring the b point to be suppressed leakage current. The point and c points will also be produced by leakage current flows into auxiliary circuits. . XFlb meter calibration station over the design of the DC can only test lOmA instrument. However, with ~ YJlO ~ steady power supply reference to culture and education, the AND, you can test with microammeter 6. But microammeter [1] J] Gt24 ~ 82 current meter power meter voltage meter Ha pick set order. . Using computer on the bridge,[link widoczny dla zalogowanych], resistance box test data processing. 0 A j,[link widoczny dla zalogowanych], Il Liding to y, 7 / 2,, At present, the amount of units in the provinces pry DC bridges and electricity, this should come into the number of homes go along the path of resistance that must be most of the orange box Comparison of bridge method is carried out. But give it to calculate result in errors. Prepared to deal with this error that the party machine Mang in the final results obtained in the process of calculation is very complicated subroutines, each of the data to calculate a process called Suo's first child. The slightest mistake will calculation errors, unnecessary procedures, to ensure the accuracy of the results of human error, and the certificate of typing a long time, the workload is the bridge of 0.02, the first measure the disk allows Ⅲ big error. To address this series of questions, to be used into the bottom of their computer asked him a whole is \Bottom arm of the permissible error ratio is also a requirement of the entire block diagram is shown in Figure l 0 or below. \The preparation of the whole bundle of this bit to \programming. By human error to call a subroutine, to ensure to the form of a dialogue with the test rules work. To pay the bridge was down 0.02, consistent with process requirements. One. Cheng J line diagram of the body shown in Figure 2. . C is in accordance with the procedures to process the request in the preparation of test procedures in the printing process, the existence of the error of the results of the machine to retain the appropriate digits. Xin Lu Gan control the amount of difference Yin Technology t992. № 12 subroutine D is rounded and even law by plaque results 『J-meter data processing, data should be counted once for each call to a subroutine D. After using computer programming. Simply the measured data input to the computer, the results can be obtained after Ang, and print out the certificate form. Between the different models that do not level of accuracy, the amount of disk number of different guillotine resistance box and the bridge are applicable. And bow. Wide; [31) by a point of order to retain the corresponding effective number of bits and corresponding bit of the whole beam. (Heilongjiang Province, metrological verification testing Liu Liping) microphone acoustic impedance Chen Ding-Yuan Tian Xiaoquan technology j knife | Abstract This paper describes the identified microphone sound pass away resistance to the reactance of the law, given the standard test promotional speaker (B & stack: 4l6O type) coupling Taiwan parameters measured with interferometer cavity exploration before the degree of interpolation obtained by the first chamber stacked plot of the equivalent I and also completion out of the microphone and the equivalent capacitance and loss curves I plot the change with frequency Qu drag. First, an overview of the acoustic impedance of the microphone standard laboratory z is a function of frequency,[link widoczny dla zalogowanych], mainly by Zhang I Ligusticum the nature of the diaphragm, after the geometry of the plate and the patch contained in the back cavity to the nature of the gas. Electric sound by the microphone can be drawn across the network reciprocity equation, the acoustic impedance of the coupling units available parameters of the equivalent series sound volume,[link widoczny dla zalogowanych], sound quality and acoustic impedance to that content can also be sound, resonance frequency and loss factor to that The content is usually low frequency sound the microphone volume of the real part of London such as given in the form. The acoustic impedance of the microphone diaphragm termination constituted by two acoustic cavity coupled sets an important part of transfer impedance. zI screen error caused by the accuracy of the potential impact of control, especially in the high-frequency part. Microphone acoustic impedance z. Can be complex impedance or
