The roundness tester is a highly precision instrument that is wildly used to measure the rotary work piece in mechanical industry. The aged roundness tester was astricted by the technique condition of that time, so its way of measurement is not at all advanced. Because these roundness testers have been used for a long time, they have a highly failure rate and their accuracy can not be insured.

圆度仪是机械工业中应用最广泛的检测回转体零件圆度误差的高精度仪器，由于老式的圆度仪受当时技术条件的限制，评定方法落后，再加上这些圆度仪的使用时间较长，使用时仪器的故障率一般都较高，测量精度也不能保证。

It is indicated that the accuracy of the measured value is determined rather by the practical relative error than by the maximum relative error. It is correct that the nearer the scale reading approaches the maximum, the more accurate the measurement is. The scale reading need not be required above 2/3X.

指出使用电表进行测量时，测量值的准确性是由其实际相对误差而非最大相对误差决定的；并非电表的读数越接近满刻度，测量值的准确性就越高；使用电表进行测量时，电表的读数不必被限定在2/3X上。
