How would you calibrate a newton meter?

Answer 1

Apply a known load to the scale and measure its change in length. According to Hooke's law, as long as the spring isn't overstressed, the force it provides is proportional to the extension.

As long as you don't overstress the spring, this means that if a 1 Newton carrot extends the spring 1 centimeter, then a 2 Newton apple will extend the spring 2 cm. You will need to mark numerous readings on the frame of the spring scale, such that you can measure various values of force

Answer 2

A digital micrometer is used exactly the same way as a standard micrometer. The only difference is the way the measurement are viewed. Here are the steps to follow for using a digital outside micrometer:

• Clean the anvil and spindle faces.
• Push the "On/Off" or any other button on some and turn it on.
• Use a test piece (supplied with the micrometer) and close the micrometer on it using the ratchet on the back of the thimble.
• Push the "Zero" or "Reset" but to set the micrometer to absolute zero.
• Push the "in/mm" button to select millimeter or inch measurements.
• You are now ready to measure a component. Always use the ratchet.

Inside micrometers work basically the same way but you can use an outside micrometer to set the inside micrometer if you have no test piece.

Answer 3

Due to its high precision measuring capabilities, sensitivity to bumps or drops, wear of the anvil and spindle faces, also wear to the spindle nut, calibration is crucial to ensure the precision of the instrument. Fine adjustments are then made to rectify any inaccuracies.
