Instructions on how to perform a point-to-point calibration in GDSLab using the calibration wizard.
For AdvDCS V2 devices, please refer to 214 GDS Helpsheet - Change, update or create transducer calibrations in AdvDCS V2-based systems
GDS Lab includes a wizard for entering tabulated calibration data and performing point by point calibrations where a single sensitivity value is not available or where there the relationship between raw output and engineering units is not linear.
To access the wizard, click on the transducer you want to calibrate in the Object Display, as shown in the image on the right.
Under the Calibration tab, click on Calibrate Transducer
If you wish to store the old calibration details you must first create a new transducer. The wizard will overwrite the calibration information for the currently selected transducer. Follow the steps shown below until you reach the calibration wizard main window.
The screenshot shows the wizard’s main window.
For tabulated calibration data you input the ‘Applied Value’ and ‘Read Value’, clicking ‘Accept’ after each pair is entered. To perform a point by point calibration you enter the applied value manually, then having selected ‘Autoread’ click accept when you have applied the force/displacement etc.
The graph and error values will update with each new data point. When you have entered sufficient data points click next to continue.
You can then choose whether to use a single best fit line for the calibration or linear interpolation between each data point (Look-up Table). The wizard will remind you of the filename used and what the equivalent sensitivity value is for the entered information.
Finally, the new calibration details will be set and you are returned to the calibration tab.
