FIELD: devices for fault finding in electric systems. SUBSTANCE: passage of signal from test connector is effected with the aid of electric circuit including ten identical stages consisting of diode, light-emitting diode, relay and resistor. Illumination of light- emitting diode of respective stage is indicative of passage of signal. List of instruments checked by means of each stage is given in test table found on front panel of instrument. Information zeroing is effected by means of RESET button. EFFECT: enhanced efficiency. 2 cl, 2 dwg
