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:

• Select the required tag from the Inventory menu.
• Click the Calibrate menu in the Module Bar and then choose Calibration History.
• Click 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.
