Tianrui cargo lifter such as precision measurement, namely in the measurement process, determine all factors or conditions constant measurement accuracy. E.g., by the same person, with the same instrument under the same conditions and with the same method, the same with a carefully measured quantity, the amount of M seeking results are based on average number of measurements are the same, it is possible that the results of each measurement the reliability and accuracy of the same. In general, in order to simplify the processing of measurement results, mostly using Precision Measurement. In fact, the absolute accuracy of measurement is impossible and so on.

2、天锐升降货梯http://www.jntr168.com/不等精度测量，即在测量过程中，决定测量精度的全部因素或条件可能完全改变或部分改变。例如，用不同的测童方法，不同的计量器具，在不同的条件下，由不同的人员对同一被测量进行不同次数的测量。显然，其测量结果的可靠性与精确程度各不相同。由于不等精度测量的数据处理比较麻烦，因此一般用于重要的科研实验中的高精度测量。另外当测量的过程和时间很长，测蚤条件变化较大时，也应按不等精度测量对待。
Tianrui cargo lifter range precision measurement, namely in the measurement process, determine all factors or conditions may completely change the measurement accuracy or partially changed. For example, children with different measurement methods, different measuring instruments under different conditions, by different individuals of the same is measured differently number of measurements. Obviously, the measurement reliability and accuracy of the results vary. Since the accuracy of the measurement data processing ranging from too much trouble, it is generally used for important scientific experiments in high-precision measurements. In addition, when the measurement process and time is very long, measuring flea condition change is large, ranging from precision measurements should also be treated.
