3.2. Impact of Time on Calibration

Try these first

1. 1.

   What is calibration?

   Hint

   Think about why we set instruments to known values.

2. 2.

   What is a standard?

   Hint

   Consider what you rely on to check measurements.

3. 3.

   What is the purpose of calibration?

   • To improve instrument design
   • To align readings with known standards
   • To reduce costs

   Hint

   Think about why measurements need to be verified.

4. 4.

   True or False: Calibration is a one-time process.

   • True
   • False

   Hint

   Consider how instruments might change over time.

5. 5.

   You suspect your pH meter readings have drifted after continuous use for two weeks. How would you determine if recalibration is required?

   Hint

   Think about how you would check for accuracy.

6. 6.

   Design a protocol for recalibrating a mass balance that has shown signs of drift over time.

   Hint

   Reflect on the steps involved in setting up a reliable calibration schedule.
