Full Title

Full titles differ between systems:

IPC:

Recording measured values > Producing one or more recordings, each recording being of the values of two or more different variables > there being a common recording element for two or more variables > the variables being recorded in predetermined sequence > in separate columns

CPC:

Recording measured values > Producing one or more recordings, each recording being of the values of two or more different variables (G01D9/38, G01D9/40 take precedence) > there being a common recording element for two or more variables > the variables being recorded in a predetermined sequence > in separate columns
