●
Check if the linearity of the lateral axle is up to standard: Install 1# and 2# probe rod on the two ends of the
lateral axle respectively (as shown in the following figure), read the corresponding CCD values from computer test
program, and then compare the values with the corresponding calibrated values in CHECK file, the difference
between them are required to be less than 2 percent;
In succession, turn the two probe rods by 180 degrees respectively, and read 1# and 2# CCD values, and then
compare them with the corresponding values from CHECK file (the same as the previous procedure), the difference
between them are required to be less than 2 percent. If the two procedures above-mentioned are all satisfied, it
indicates that the linearity of this calibration frame is up to standard, and can be used. After installing the two
vertical axles, the calibration frame installation procedures are finished.
