A calibrator is used to adjust the accuracy of an instrument to ensure that it performs as expected and meets quality standards. It allows the user to create, set, store and recall simulation profiles of an instrument to function with. The purpose of using calibrator is to ensure the accuracy of the outputs.
The accuracy can have a broad range of definitions and is affected by many parameters in the system. Accuracy can be defined as the difference/error between the true value and the measured value or how close a measured value is to the actual value. In reality, the true value is hardly obtained due to the limitation of measurement method and tools we used, while calibration is to compensate systematic errors of the measurement to improve the accuracy of the results. Calibration assumes a profile for the relationship between the actual value and the measured value. This profile depends on the characteristics of the components used in the measurement. There are two calibration profiles: one corrects for offset error only, and the second accounts for both offset and gain errors. Figure 1 illustrates these typical profiles that define the calibration implementation methodology and Figure 2 explains the relationship between the actual value and measured value.
Bestech Australia offers extreme high accuracy, robust calibrators for the field and lab with long term stability. Provide calibration source for mechanical (force, torque, displacement, pressure, strain, acceleration, etc.) and electrical (voltage, current, thermocouples, temperature, and resistance) measurements. Our calibrators can be used to simulate outputs from various transducers, thereby simplifying troubleshooting, verification and calibration processes for test systems.
