FIELD: measurement technology, measurement of parameters of electric circuits. SUBSTANCE: device measuring inductance of coils has source of constant voltage which one lead is grounded and which other lead is connected to first lead-out of electron controlled key, two parallel branches (one branch comprising resistor and inductance coil connected in series, another branch made up of resistor and capacitor connected in series), indicator in the form of oscillograph with two inputs, one lead being grounded and common for both inputs, control circuit which first output is connected to input of indicator and which second output is connected to control input of electron controlled key. Ungrounded lead of second input of indicator is connected to common lead of both resistors of two branches. EFFECT: decreased measurement errors. 2 dwg
