A calibration is a process that compares a known (the standard) against an unknown (the customer's device). During the calibration process, the offset between these two devices is quantified and the customer's device is adjusted back into tolerance (if possible). A true calibration usually contains both "as found" and "as left" data.
A validation is a detailed process of confirming that the instrument is installed correctly, that it is operating effectively, and that it is performing without error. Because a validation must test all three of these operational parameters, it is broken into three different tests: the installation qualification (IQ), the operational qualification (OQ), and the performance qualification (PQ).

What is the difference between calibration sensitivity and analytical sensitivity?
Calibration Sensitivity(m): slope of acalibration curve at the consentration of interest y=mx+n m:slope(Calibration Sensitivity) x:concentration n:signal of blank Analytical Sensitivity: response to noise ratio A.S=m/S m:slope S:standard deviation of the measurement
What is the difference between calibration and measurement?
Calibration is a comparison between measurements - one of known magnitude or correctness made or set with one device and another measurement made in as similar a way as possible with a second device. The device with the known or assigned correctness is called the standard. The second device is the unit under test, test instrument, or any of several other names for the device being calibrated. This definition source : Wikipedia.

What is the difference between SDLC and STLC?
SDLC has both verification and validation activities where as STLC has only validation activity. Simply STLC is a part of SDLC
What is calibrated?
Calibration is the validation of specific measurement techniques and equipment. At the simplest level, calibration is a comparison between measurements-one of known magnitude or correctness made or set with one device and another measurement made in as similar a way as possible with a second device Calibration is the validation of specific measurement techniques and equipment. At the simplest level, calibration is a comparison between measurements-one of known magnitude or correctness made or set with one device and another measurement made in as similar a way as possible with a second device

How do you make a calibration for differential pressure?
Differential pressure is the difference between two pressures. So, P2-P1.
What is the difference between data varification and data validation?
Data validation makes sure that the data is clean, correct and meaningful, while data verification ensures that all copies of the data are as good as the original.
What is the difference between defect detection and defect prevention?
The defects detection is the validation process. The defects prevention is a verification process.
What is the difference between calibration sensitivity and analytical sensitivity?
Calibration Sensitivity(m): slope of acalibration curve at the consentration of interest y=mx+n m:slope(Calibration Sensitivity) x:concentration n:signal of blank Analytical Sensitivity: response to noise ratio A.S=m/S m:slope S:standard deviation of the measurement
What is theDifference between concurrent and prospective validation in pharmaceutical?
If a validation study is conducted before placing a product in the market, then it is called prospective validation. If a product is placed on the market during the validation study, it is called as concurrent validation.
What is the difference between field level and record level validation rule?
The information entered and how the information is entered is a very dominate role in field/record level validation. However they share the same goal to enforce rules consistently, to write less code.
