Which instrument is used for calibration?
Here, accuracy of the scale is the main parameter for calibration. In addition, these instruments are also calibrated for zero error in the fully closed position and flatness and parallelism of the measuring surfaces. For the calibration of the scale, a calibrated slip gauge is used.
When should the measuring instruments be calibrated?
WIKA’s recommendation for a calibration check and re-certification is once every 12 months. However, the frequency for a calibration check of a measuring instrument depends on many factors: What are the operating conditions of the instrument?
What happens if equipment is not calibrated?
INACCURATE RESULTS: If you do not calibrate your equipment, it will not give accurate measurements. When the measurements are not accurate, the final results will also be inaccurate, and the quality of the product will be sub-standard.
What are the types of calibration?
Different Types of Calibration
- Pressure Calibration.
- Temperature Calibration.
- Flow Calibration.
- Pipette Calibration.
- Electrical calibration.
- Mechanical calibration.
What is the process of calibration?
Calibration is the process of configuring an instrument to provide a result for a sample within an acceptable range. The instrument can then provide more accurate results when samples of unknown values are tested in the normal usage of the product.
What is the recommended calibration frequency?
The standard periodicity of calibration of the measuring instrument is annual, except for the most critical instruments which, under normal operating conditions, should be recalibrated at least twice a year.
What is the importance of calibration?
The goal of calibration is to minimise any measurement uncertainty by ensuring the accuracy of test equipment. Calibration quantifies and controls errors or uncertainties within measurement processes to an acceptable level.
What are the benefits of calibration?
The purpose of calibration is to help assure precise measurements. The benefits of calibration include improving safety as well as saving money and increasing profitability by avoiding the costs of false acceptance and rejection of products, increasing production efficiency, and extending the life of equipment.

How is the calibration of a measuring instrument done?
Calibration of the measuring instrument is the process in which the readings obtained from the instrument are compared with the sub-standards in the laboratory at several points along the scale of the instrument. As per the results obtained from the readings obtained of the instrument and the sub-standards, the curve is plotted.
What should be the ratio of standard to calibration?
Calibration is a comparison between a known measurement (the standard) and the measurement using your instrument. Typically, the accuracy of the standard should be ten times the accuracy of the measuring device being tested. However, an accuracy ratio of 3:1 is acceptable by most standards organizations.
What should be the accuracy ratio of a measuring instrument?
Typically, the accuracy of the standard should be ten times the accuracy of the measuring device being tested. However, accuracy ratio of 3:1 is acceptable by most standards organizations. Calibration of your measuring instruments has two objectives. It checks the accuracy of the instrument and it determines the traceability of the measurement.
What is the difference between verification and calibration?
Calibration – for the firm’s standards and the transfer standards used as references. Verification – for most measuring instruments that the user needs to know they are reliable, regardless of the specifications of the measurement to carry out.
