There are 2 types of calibration intervals that we need to complete here, these are:

1. Initial Calibration Interval

2. Final or Fixed Calibration Interval

First, let us determine some main objectives for implementing calibration interval analysis.

4 Major Objectives For Implementing Calibration Interval Analysis

1. To designate Initial Calibration Intervals – this is the starting calibration interval based on experience and recommendations.

2. Use to extend interval of calibration – this means that a given calibration interval will be extended for a specific period until a fixed interval is reached. This is also applicable like for example during this pandemic where calibration is difficult to access and we want to extend a little more temporarily.

3. Use  to reduce interval of calibration – this is applicable when we encounter out of tolerance where calibration is reduced as per implementation rule. See below example presentation

4. Use to determine the fixed calibration interval (final interval) – this is the main calibration interval that we need to achieve based on actual use which should be adequately justified
