Introduced: September 1968

Title

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 current or voltage obtained from a reference source

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 current or voltage obtained from a reference source (G01R27/16, G01R27/20, G01R27/22 take precedence)
