System and method for updating a compensation value of a measurement machine

A computer-based method for updating a compensation value of a measurement machine, the method comprising:

• (a) controlling the measurement machine to measure a dimension of a standard object and obtaining a measured value of the standard object;
• (b) calculating a difference between the measured value and a real value of the standard object to obtain the new compensation value of the measurement machine;
• (c) decrypting an encrypted authorization document which is generated by a host computer and obtaining an authorization code and a user input identifier (ID) from the decrypted authorization document;
• and
• (d) updating a compensation value stored in a storage system of the client computer with the new compensation value if the user input ID is the same as an ID stored in a control card of the measurement machine and the authorization code has expired.

A computer-readable medium having stored therein instructions that, when executed by a client computer, cause the client computer to perform a method for updating compensation value of a measurement machine, the method comprising:

• (a) controlling the measurement machine to measure a dimension of a standard object and obtaining a measured value of the standard object;
• (b) calculating a difference between the measured value and a real value of the standard object to obtain the new compensation value of the measurement machine;
• (c) decrypting an encrypted authorization document which is generated by a host computer and obtaining an authorization code and a user input identifier (ID) from the decrypted authorization document;
• and
• (d) updating a compensation value stored in a storage system of the client computer with the new compensation value if the user input ID is the same as an ID stored in a control card of the measurement machine and the authorization code has expired.
