    Digital outside micrometer zeroing method

    1. Wipe the probe measuring
    2. Probe closure
    3. Lock the screw with the stopper
    4. Use a wrench to pull the fixing sleeve until the zero line is aligned

    Q1: Is the sisco digital micrometer accurate?
    A1: sisco digital micrometers can display accurate measurements in small ranges. Advanced and more accurate models can easily measure distances down to 0.001mm. This accuracy when measuring small objects translates into accuracy for the entire project being carried out.

    Q2: What is a digital micrometer?
    A2: The digital micrometer is the outside diameter micrometer that uses electronic measurement, digital display, and the principle of the spiral sub to read the distance between the two measuring surfaces on the ruler frame.

    Q3: What are the ranges of sisco digital micrometers?
    A3: sisco digital micrometer has 4 ranges available: 0-25mm (0~1 inch), 25-50mm (1-2 inch), 50-75mm (2~3 inch), and 75-100mm (3~4 inch).

    Tips: What is the difference between inside diameter micrometer and outside diameter micrometer?

    The difference is that the inside diameter micrometer is to measure the diameter of the inner hole, the outside diameter micrometer is to measure the diameter of the outer circle, but also can measure the thickness of the inside diameter micrometer for the precision measurement of internal dimensions (divided into monoblock type and connecting rod )

    The correct measurement method: inside diameter micrometer in the measurement and its use of the largest size of the rod and its micrometer head connected, in turn down to the measurement contact, with the inside diameter of the ruler to measure the hole will be measured contact measuring surface support in the measured surface to adjust the differential cylinder, so that the differential cylinder side of the measuring surface in the radial section of the hole swing to find the minimum size, and then tighten the set screw to remove and read, there is no tightening screw directly There are also direct readings without tightening the screw.
