Tork Craft Vernier 150Mm Carbon Steel Metric 0.02 Acc

Description

Range: 150mm
Accuracy: 0.02mm

Application:

The Tork Craft Vernier Calipers are used to measure internal and external
measurements

• Micro adjustment wheel
• Jaw lock screw
• Metric/Inch reading scale
• Accuracy of 0.02mm

Safety Tips:

• Make sure the workpiece being measured is clean and has no burrs on the edges.
• When measuring a workpiece in a lathe, ensure that it is switched off
• Keep precision measuring tools away from magnetic objects

WARNING: Using any tool can be dangerous. Always select
the right tool for the job. Do not drop, engrave or bend

Features

How to use and read an analog vernier caliper:

1. Undo the locking screw and open the jaws of the caliper and position
   both jaws firmly to the ends of the piece being measured.
2. Tighten the locking screw so that the jaws don’t move.
3. The vernier is divided into two different measurement scales. The main
   scale and the vernier scale (fixed onto the bottom jaw).
4. On the vernier scale is a small number 0. Look at how many markings the
   0 has passed on the main scale. This represents the amount of millimetres
   measured.
5. The decimal is determined by the alignment of the markings on the vernier
   scale to the main scale. The first alignment from left to right will be the
   decimal reading accurate to 0.02mm.
6. On the diagram below is an example of a piece measured at Ø17.28mm.
7. This method can be used to measure:
   • Depth by using the stem.
   • Inner dimensions by using the inner jaws.
   • Outer dimensions by using the outer jaws.

Handling and care of vernier calipers:

• The inside faces of the jaws and the outside tips must be treated with
  great care. The tool will no longer give accurate readings if the jaws are
  bent or worn.
• Wipe the faces of the vernier caliper clean from dust or dirt.
• The accuracy should be periodically checked by measuring a known dimension.
• Analog vernier calipers should be lightly oiled to
  prevent rust.
• A vernier caliper is a measuring instrument and should be safely stowed
  away to prevent any damage that might occur.
