(1) Digital display to eliminate backlash and improve precision(2) Advanced trigonometric calculation so to accomplish a perfect project. (3) 11.6wide display to offer excellent long-distance viewing. (4) Digital readout kit can avoid wasting weeks to check machine precision. (6) 1pc digital readout(2Axis/3Axis) with scales(upon your options), 5? M (0.0002) resolution (at 45ºC). Q1 : are the length 100, 150, 200…. 1000mm travel length or total? Answer : all are travel length. Q2: if i need 200mm, 450mm scales with 2axis digital readout, how should i do? Q3 : what does the dro measure to? Answer : measure to 0.005mm, 0.0002inch (1inch=25.4mm). Q4 : if i need a scale like 255mm, can you offer it? Answer : 250mm is enough, its measuring range can reach up to 270mm, so you can use if you need to measure 255mm. Q5 : Can i cut the scales by myself? Answer : Technically NO, it maybe unavailable after cutting. Q6: Do you have English user manual? Answer : yes, it comes with the dro box. Q7: Do you have other higher precision type, such as measure to 0.001mm? Q8: Is it easy to install these scales and dro? Answer : Please must check the scale pin definition (1,2,3,4,5,6,7,8,9), which is very important!!
