最后，分析了由基准误差引入的参数标定误差。
At last, the calibration error aroused by reference panel error is analyzed.
仪器制造商常常先规定基准严格的初始误差，以便组装后的室温系统无需进行校准。
Often INSTRUMENT manufacturers will specify a reference with a tight initial error so they do not have to perform room-temperature SYSTEMs calibration after assembly.
随着新基准的不同选择，相对点位误差可有多种含义。
Relative positional error may have different meanings with the different new datum choosing.
