    I remember seeing somewhere that cheap hobby level products are BANNED from discussing on this forum. All those DROs by Electronica, Easson, etc fall into this category. That is something you can...

    I would stay away from the cheap Chinese scales if budget allows. Accuracy grade aside, they are all based on the same 40 year old design which is prone to premature aging and failure, especially if...

    Yes, I will ask our web guy to add those to the online store next week.

    This requirement is based on satisfying starting current requirements, so the directly connected 3 phase motor spins up to speed in under 2 seconds or so. It does not really apply to the inverter...

    I would not recommend any low cost imports such as Sino, Ditron, Eason, DROpros, Grizzly etc to a professional customer, especially if you plan on using a tool library feature. While they all...

    I would start with measuring a recently certified block, and see how close your results match with a 3rd party calibration lab, and if the difference is less than uncertainty of measurement.
    As...

    A word of caution here. Many things can go wrong with this procedure if the operator is not experienced. Just one of the examples: if stop is not indicated in, each degree of tilt will cause 0.001"...

    This is the same as Easson/DROPros. While some of those scales come with a differential EIA422 output, we are yet to see a single low cost DRO which would actually use the benefits of EIA422 as all...

    Very good point. We will consider adding this feature to the next software release for DR400 series of Digital Readouts.



    It is small, typically less than 1 resolution count, but every sealed...

    DRO will measure linear distance with an error of +/- 1 resolution count + glass error + temperature error + way straightness + play in the gibs + drilling/reaming accuracy. Doing square pattern will...

    LED might be hard to see, those are typically IR, only a tiny red spot can be seen in a dark room and if looking straight. Replacing LED might not be as straight forward as you think. That scale...

    DRO-Pros are made by a Chinese company Easson, they use a typical 5V TTL quadrature protocol. The generic scale you have is probably wired differently from Easson and without looking inside of it,...

    Newall scales are based on inductive scanning principle.

    If precision is critical for the application, then optical glass scales are number 1 choice. They provide exceptional accuracy and...

    I've seen both case hardened and through hardened rails. Considering it did not deform but snapped like cast iron, very likely this particular one was through hardened.

    One more clarification...

    Those linear rails are typically made out of hardened steel, think ball bearing race. Hard but brittle. They are also ground to a high level of precision, so making it in house would be close to...
