对于常规仪器来说，仪器可靠性的关键是仪器的所有部件都是可靠的。下面是常

For the conventional instrument, the instrument key to reliability of all components of the instrument are reliable. Here is the process of conventional instrument. As shown in FIG l, F (x) for the operation of the circuit of the instrument, x is a generalized input signal, which includes not only the signal of each measurement object, further comprising a power source. Y is the output signal of the instrument. For conventional equipment, if the various components of the instrument as a series system, as long as the integrity of the components, each component normally ensure that y = F (x) and the calculation of the correct operation, the system will have the correct output. If interference occurs, x becomes unfolded x ', the instrument still performs F (x' operation), the output error. Once the interference disappears, as long as the instrument element intact, the instrument output will return to normal.

For conventional instruments, the key to instrument reliability is that all components of the instrument are reliable. The following is the process of a regular instrument. As shown in Figure l, F(x) is the working circuit of the instrument and x is a broad input signal that includes not only the signal of each measurement object, but also the power supply. Y is the output signal of the instrument. For conventional instruments, if the parts of the instrument as a series system, as long as the components are intact, the components are normal, to ensure the correct operation and calculation of y-F(x), the system will have the correct output. If interference occurs, x becomes expanded x', and the instrument still performs F(x') operations with an output error. Once the interference is gone, the output of the instrument returns to normal as long as the components in the instrument are intact.

For conventional instruments, the key to instrument reliability is that all parts of the instrument are reliable. The following is the process of conventional instruments. As shown in Figure L, f (x) is the working circuit of the instrument, and X is the generalized input signal, including not only the signal of each measurement object, but also the power supply. Y is the output signal of the instrument. For conventional instruments, if each part of the instrument is regarded as a series system, the system will have correct output as long as each part is in good condition and each part is normal to ensure the correct operation and calculation of y = f (x). If there is interference, X becomes the expanded X ', the instrument still performs the operation of F (x') and outputs an error. Once the interference disappears, as long as the components in the instrument are intact, the output of the instrument will return to normal.
