Related Requirements:
1, according to the need to adjust the measuring instruments
Adjustment refers to the measurement of the accuracy of the instruments and other performance to meet the specified requirements of the operation. Adjustment should comply with the operating procedures of measuring instruments to prevent improper adjustment and inaccuracy. Such as multimeter, vernier calipers, etc. before use should be zeroed and adjusted.
2, the calibration of measuring instruments labeled state
Generally in the calibration of measuring instruments on the state label, so that the user understands the state of measuring instruments (qualified, limited use, out of service, etc.) and expiration date.
Because of the small size or impact on the operation of measuring instruments and other reasons and should not be labeled, its calibration status label can be affixed to the box or by the user for safekeeping, but the instrument should be engraved with a number for easy traceability.
3, to prevent calibration failure when adjusting
Measures to prevent calibration failure when adjusting. For example, the qualification of operators, must have a qualification certificate to work, and at the same time, the preparation of adjustment instructions and calibration points for sealing, and so on.
4, strengthen the handling, maintenance, storage protection
In the use of measuring instruments in the process, we must take measures to prevent measuring instruments in the handling, maintenance and storage damage or failure. Such as providing suitable environmental conditions, take protective measures.
5, do a good job of measuring instruments out of time
If found that the measuring instruments deviate from the calibration state (out of calibration), it should be reported to the supervisor, requesting an evaluation of the validity of the test results, and the equipment and affected products to take appropriate measures.
