• G01D 1/02 giving mean values, e.g. root means square values (measuring root mean square values of currents or voltages G01R19/02)
• G01D 1/04 giving integrated values (giving mean values G01D1/02)
• G01D 1/10 giving differentiated values
• G01D 1/12 giving a maximum or minimum of a value
• G01D 1/14 giving a distribution function of a value, i.e. number of times the value comes within specified ranges of amplitude
• G01D 1/16 giving a value which is a function of two or more values, e.g. product or ratio
• G01D 1/18 with arrangements for signalling that a predetermined value of an unspecified parameter has been exceeded (G01D1/14 takes precedence)
