Historical calibration data can be used to show how well a piece of equipment is performing by plotting the data as a chart.

Note: Not all calibrations have charts available. Only calibration templates that have errors and tolerance can be charted.

To chart the calibration history for a tag:

First select the required tag from the Inventory menu.

Go to the 'Calibration History' screen.

Click on one of the calibrations in the list.

Click the 'Chart' button in the database bar.

The chart plots the errors and tolerances for the selected calibration, showing the calibration data graphically over time.

This chart can be printed by clicking the 'Print' button.
