Repair project (brand not limited to): 
 1, digital calipers: denial or accuracy appears uneven veneer external claws amount of serious wear, the larger the gap, pushing hands damaged, incomplete or missing digital picture display, sliding flow, foot body wear, the depth of foot wear, missing parts and so on. 
 2, scale: dial scale, the accuracy appears not allowed, pointer jumping, not zero, the cover is damaged, the main deformation measuring rod can slide up and down the main gear missing teeth or wear, deformation or damage to oil silk, etc. - -. 
 3, the lever table: precision are not allowed to appear, pointer jumping, not zero, the cover is damaged, oil silk deformation, pivot damaged gear sector positioning pin damage, damage, etc. --- the central axis. 
 4, Projector: No accuracy, X axis within the bearing severe wear, fuzzy video projector, lens, optical lens set of fuzzy measurement table X / Y axis screw, rail has rust stains, long-term lack of maintenance, etc. - -. 
 5 microscope: optical imaging is not clear, cross-line offset, up and down movements smooth not smooth, long-term lack of maintenance of the machine, X, Y axis signal transmission abnormalities, displayed value adjustment, the upper and lower light source power supply circuit damage, X, Y-axis range --- insufficient. 
 6, video measuring instrument: precision allowed, X-axis within the bearing severe wear, rail has rust stains, long-term lack of maintenance, light a candle or light source bright enough, the end does not light, X, Y-axis data synchronization beating - -. 
 7, the projector electronic probe, tool microscope, the first electronic differential, the data are not allowed, cable broken, damaged or button out of control keys, etc. ---. 
 8, the height scale: Table height gauge, handle gear wear, not work, the next upgrade, fine
