What are the various calibration methods?

Image
There are several calibration methods used depending on the type of instrument being calibrated and the required level of accuracy. Here are some common calibration methods: 1. Comparison Calibration: This method involves comparing the instrument being calibrated directly to a standard reference instrument of higher accuracy. 2. Static Calibration: In this method, the instrument being calibrated remains stationary while the standard reference is applied to it. This is common in calibrating temperature sensors, pressure gauges, and other similar devices. 3. Dynamic Calibration: Dynamic calibration involves subjecting the instrument being calibrated to varying conditions or inputs while comparing its response to the standard reference. 4. Interpolation Calibration: This method involves calibrating an instrument based on interpolation between known calibration points. This is useful when it's impractical or expensive to calibrate at every desired measurement point. 5. Ratio Calibrat...
