The Adjustment refers to the deliberate adjustment of a measuring instrument, sensor, or measuring system to minimize measurement errors and improve measurement accuracy. The goal of calibration is to ensure that the displayed or output measurement values correspond as closely as possible to the actual reference values.
Adjustments are made frequently after a Calibration, if it was determined that the measuring instrument was measuring outside the permissible tolerances. While calibration merely determines and documents the measurement deviation, adjustment actively modifies the measuring instrument to correct this deviation.
Difference Between Calibration and Adjustment
The terms Calibration and Adjustment are often confused, but they describe different processes:
- Calibration: Determining and documenting the deviation of a measuring instrument from a known reference standard. In this process, the measuring instrument is not changed.
- Adjustment: Targeted correction or adjustment of the measuring instrument to reduce or eliminate the detected measurement deviations.
In practice, calibration is often performed first, followed by adjustment—if necessary—and then recalibration to verify the achieved measurement accuracy.
Why is an adjustment important?
Over the course of their use, measuring instruments are subject to various factors that can affect their accuracy. These include, for example:
- Aging of Electronic Components
- Mechanical Wear
- Effects of Temperature and Humidity
- Shocks and Vibrations
- High operational loads
- Long-Term Drift of Sensors
Regular calibration helps to compensate for these factors and ensure consistently accurate measurement results.
Typical Applications
Calibrations are required in nearly all areas of industrial measurement technology, for example in:
- Temperature measuring devices
- Pressure Sensors
- Force and Torque Sensors
- Flow meters
- Scales
- Electrical measuring instruments
- Measurement data acquisition systems in the laboratory and in production
Regular calibrations and, where necessary, adjustments are essential, particularly in quality-critical applications as well as in research, development, and testing.
Calibration in Delphin Measurement Technology
Measurement Data Acquisition Systems from Delphin Technology enable the high-precision measurement of a wide variety of parameters. To ensure consistently reliable measurement results, connected sensors and measuring instruments should be calibrated regularly in accordance with the manufacturer’s specifications and—if necessary—adjusted.
Thanks to their combination of precise data acquisition, high long-term stability, and the ability to document calibration and testing processes, Delphin systems are particularly well-suited for demanding applications in test bench technology, process measurement technology, and research and development.
