When should calibration be performed?

Instruments should be calibrated at the following times:

• Scheduled Maintenance: Calibration should take place according to a set schedule to make sure regular maintenance is being carried out. This helps keep equipment in good working condition.

• After Repairs and Changes: If equipment has been repaired or modified, it should be recalibrated to check that it still measures accurately.

• When Accuracy is in Question: If it seems that an instrument isn’t measuring accurately, it should be calibrated as soon as possible. Signs that calibration might be needed include physical damage to the instrument or unusual readings.

• Before Critical Measurements: If an instrument is being used for a critical measurement, such as during final product testing, it is advised to calibrate it.
