Information Sheet 2.1
Safe handling procedures and care of measuring instruments
Every property must be taken care with concern. Like a good manager looking for the welfare of his duty can be compared to a person who is responsible in keeping his personal belongings. The same is true in handling your tools. Tools, like measuring instruments must be handled with great caution. Aside from their expensive cost and delicate use, they are also sensitive. Even a slight accidental bump can affect the calibration and internal parts especially those that are made of electronic.
To protect your measuring instruments from mishandling, safety procedures must be followed at all times to ensure freedom from risk of danger and threat of thieves.
The following are basic rules to consider in managing your measuring instruments.
1. Always keep your receipt of purchase. This is one way of ensuring your measuring tools of their warranty if something happens to your tools. This will give you a good exchange of a new one if manufacturer's defect is the cause of the defect.
2. Always follow safety instructions. The safety instructions in owner;s manual will be you guiding information on what and what not to do with your instruments. This will assure you of the proper use and step-by-step procedures if calibration is needed.
3. Always match the type of job with your instruments. Matching of job with your instrument is important. Do not use your instrument if it is not intended for tough job.
4. Always handle your measuring instruments safely. Never use your tools to point at somebody or use for joke or play. Remember, measuring tools are expensive.
