How do you calibrate a combination square?

Answer 1

Calibration of vernier calliper can be done using slip guages i.e. mirror finished rectangular blocks of alloy steel having different sizes & error less than one micrometer. These blocks can be joined together by sliding polished faces over each other to get disired length. Measuring this length & compairing the actual reading, we can calibrate the equipment.

Answer 2

To calibrate a combination square, you can check the accuracy of the 90-degree angle by placing the square against a known straight edge to verify that it is square. You can also use a protractor to measure the angle. If the square is out of alignment, you may need to adjust it by loosening the screw on the ruler and repositioning it until it reads 90 degrees.

Answer 3

One can use gear tooth vernier calipers by first setting the instrument's chordal addendum on the addendum vernier. After this, one should straddle the gear tooth with the caliper, bringing the tooth together until no jiggling about can be felt anymore.

Answer 4

You can use angle block gauges to calibrate the measuring head with blade of combination set.

Answer 5

callibration of vernier caliper. It is calibrated base on the type , if it is 49/50, the 10th division of vernier scale will correspond with 9th division of the vernier scale

Answer 6

Do not force the caliper when using it.
