G01R 11/17 Compensating for errors; Adjusting or regulating means therefor
Introduced: July 1974
Full Title
Full titles differ between systems:
IPC:
Electromechanical arrangements for measuring time integral of electric power or current, e.g. of consumption > Constructional details > Compensating for errors; Adjusting or regulating means therefor
CPC:
Electromechanical arrangements for measuring time integral of electric power or current, e.g. of consumption (monitoring electric consumption of electrically-propelled vehicles B60L3/00) > Constructional details > Compensating for errors; Adjusting or regulating means therefor
IPC and CPC are identically structured here. All 6 subcodes exist in both systems.
1 shared codes have differing titles between IPC and CPC.
