(接上期)九、仪器偏移仪器偏移是重复测量示值的平均值减去参考量值,是测量仪器示值的系统误差。仪器偏移通常用适当次数重复测量的示值误差的平均值来估计。重复性测量条件是指相同测量程序、相同操作者、相同测量系统、相同操作条件和相同地点,并在短时间内对同一或类似被测对象重复测量的一组测量条件。测量重复性是重复性 (Continued) Nine, instrument offset Instrument offset is the average of repeated measurements indicate the value minus the reference value is the system error of the instrument shows the value. The instrument offset is usually estimated by averaging the indicated error of the measurements repeated for the appropriate number of times. Repetitive measurement conditions refer to the same measurement procedure, the same operator, the same measurement system, the same operating conditions and the same place, and in a short period of time on the same or similar test repeated measurements of a set of measurement conditions. Repeatability is reproducibility
