G01R 27/10

using two-coil or crossed-coil instruments forming quotient

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Arrangements for measuring resistance, reactance, impedance, or electric characteristics derived therefrom > Measuring real or complex resistance, reactance, impedance, or other two-pole characteristics derived therefrom, e.g. time constant > Measuring resistance by measuring both voltage and current > using two-coil or crossed-coil instruments forming quotient

CPC:

Arrangements for measuring resistance, reactance, impedance, or electric characteristics derived therefrom > Measuring real or complex resistance, reactance, impedance, or other two-pole characteristics derived therefrom, e.g. time constant (by measuring phase angle only G01R25/00) > Measuring resistance by measuring both voltage and current > using two-coil or crossed-coil instruments forming quotient

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
