Did you know that to measure is not only to use the measuring instrument and take the measurement, NO!, it is more than that, with these simple and basic Rules To Make A Good Measurement, we guarantee that the instrument is used properly, that it will have a long life and that the measurement we make will always be the correct one.
We must made measurements with due accuracy and care; for this purpose we must use the instrument that corresponds to the required precision. In addition, we must take in consideration some indications as the followings:
- Clean the surfaces of the object and the instrument before measuring.
- Deburr the workpieces beforehand.
- When taking precision measurements, pay particular attention to the reference temperature (if the workpieces have been heated by machining, they must be set aside until they recover their reference temperature).
- On some measuring instruments it is necessary to ensure that the measuring pressure is accurate. We never must use force.
- Magnetized workpieces (e.g. by magnetic clamping) must be demagnetized before measuring.
- Check the adjustable measuring instruments repeatedly for their zero position.
- Check the measuring instruments for measuring accuracy at certain intervals.
To Make a Good Measurement Requires Care
The instruments used to measure must be treated with great care, as this is the only way to guarantee correct measurements. In order to keep them in perfect condition, it is advisable to keep these recommendations in mind:
- Keep them separate from the tools (e.g. on a support lever).
- Place the sensitive instruments on a soft base (which can be a piece of felt or a clean cloth), protecting them from dirt.
- Preserve them from heat and cold.
- Do not drop them.
- Put them down carefully after use, cleaning them if necessary (remember that instruments exposed to oxidation must be treated with acid-free or grease-free oil).
