Further Discussion on the Error Adjustment of Indication Figure of TH320 Rockwell AccelerometerZONG Bin, WANG Er-ping, WEI Jian-zhong College of Materials Science and Engineering, Beijing University of Technology, Beijing 100022, ChinaAbstract:Through the subsection digital adjustment, TH320 Rockwell accelerometer gets over the difficulty in adjustment experienced by common Rockwell Accelerometer due to poor demonstration linearity, thus the value indication adjustment becomes easy and convenient. Meanwhile, the error adjustment of each rigidity range of TH320 is independent from each other, namely the error correction value of certain section has no impact on the correction range of other sections. In this article, tests of actual data are summed up to further illustrate the features of TH320 in indication value adjustment, particularly in terms of utilizing the limited number of standard blocks to correct the figures of the whole testing range of the scales.[著者文摘]
