No, these are two different numbers. The Reference/Calibration tool number is a unique identification number for the specific tool used to calibrate your DotScan cube. The Serial Number, on the other hand, is a unique identification number for your DotScan cube itself.
If you need to track the corresponding Reference/Calibration tool number for your DotScan cube, you can provide the Serial Number of your cube to Arden. We will be able to provide you with the corresponding Reference/Calibration tool number.
If you have any further questions or concerns, please contact technical support at Arden software.
