Question:

What is the purpose of instrument calibration?

A to ensure the accuracy of its measurement
Explaination

All of the instruments used in the pharmacy are required to be very accurate to ensure the purest quality and the best possible product. To maintain the accuracy of the instruments, regular cleaning and maintenance is needed. This often includes calibration where a standard is used to make minor modifications to the measurements the device makes so that it meets the highest possible standards of accuracy. An example of this would be a scale used to measure ingredients for a compound or the volume dispensed in an automatic TPN compounding machine.
