Carbon Steel Outside Micrometer 0-25mm/0.001mm Gauge Vernier Caliper Measuring Tool Professional Micrometer Gauging Tools

Description

Specification:

Material: carbon steel

Measuring range: 25

Resolution: 0.001

Scope of application: 25

Specifications: Micrometer 0-25

Feature:

Outer diameter micrometer the external
dimensions measuring instruments, measure the distance between the two sides of
the square frame by use of helix principle. Outer diameter micrometer is mainly
used for measuring a variety of external dimensions.

Diameter micrometer dividing value is
0.01mm, the upper limit of measurement range is not more than 300mm, divided
into a 25mm per specification. Such as 0-25mm, 25-50mm …… and so on.

Diameter micrometer form shown in the
picture: The picture is for illustration only, does not indicate the detailed
structure.

Instructions for use:

1. Clean the measuring surface before use
and correct the zero position. 0-25mm direct alignment zero: 25mm above use the
bar gauge aimed at quasi-zero.

2. Zero correction method: If the 0-bit
line is not aligned with the baseline, first loose screw with a screwdriver
slightly, with a wrench to adjust the baseline position, so that the baseline
alignment 0 taste bit line, then tighten the screws. See instructions for use
picture 2

3. When measuring, the micrometer should be
perpendicular to the work piece under test, rotating force measuring device,
the measuring surface in contact with the work piece should be rotating gently,
when the force measuring device issued a slight click, click …
sound, That is the actual size of the work piece under test.

4. Locking device can be passive
measurement of micro-screw back and forth. Relax to the right and lock to the
left. See instructions for use Figure 3

5. When measuring, the left hand should
hold the heat shield to prevent body temperature transmitted to the micrometer,
causing measurement error.

6. One end of the wrench can be adjusted
zero, the other end can pull the force measuring device.

Warm tips:

1. Micrometer is a precision measuring
tool, when used gently, after use in the exposed parts coated with anti-rust
oil, and placed in the box, put it at the dry and ventilated place.

2. Measurement cannot force the
micro-rotation cylinder, so as not to damage the accuracy.
