Hukumomin daɗi na ƙarfin weston type frequency meter shine “idani karamin ruwa ta ƙare ɗaya da ɗaya a ƙoƙarin ɗaya, saboda hakan zai samun magnetic fields kuma har zuwa magnetic field mai tsarki don nuna yadda ƙarin ya ƙara a cikin ɗaya”. Tsarin weston frequency tana dacewa da ferrodynamic type of frequency meter. Don in yi diagram na circuit, munka so kuɗi biyu, inductors uku da kuɗi biyu.

Wannan ne diagram na circuit na weston type frequency meter.

Axis na ƙoƙari biyu ana bayyana kamar yadda aka nufin. Scale na ɗaya an samun kamar yadda akwai ido a lokacin ƙarin daɗi, za mu shiga wuraren 45o. Ƙoƙarin 1 tana da kuɗi mai tsawon R1 da inductor mai tsawon L1, amma ƙoƙarin 2 tana da inductor mai tsawon L2 da kuɗi mai tsayi R2. Inductor mai tsawon L0 tana shirya waɗanda ke ƙarƙashin ƙaramin ruwa don inganta ƙarin mai yawa, wanda ake magana a kan wannan inductor tana yi ƙarƙashin filter circuit. Bincika hukumomin ɗin ɗaya.

Idan a yi ƙaramin voltage a ƙarin daɗi, ido za shiga wuraren normal, idan ƙarin ya ƙara, za mu iya duba cewa ido ya ƙara zuwa baya daakaɗa a cikin diagram na circuit. Idan ƙarin ya ƙara, ido za ƙara zuwa baki, idan ƙarin ya ƙara ƙarin daɗi, za mu iya duba cewa ido ya ƙara zuwa baya daakaɗa a cikin diagram na circuit.

Bincika ƙarfin ɗin ɗaya. Voltage drop across an inductor tana ƙara da ƙarin daɗi, idan ƙarin ya ƙara, voltage drop across the inductor L1 ya ƙara, cewa voltage impressed between the coil 1 ya ƙara, saboda hakan current through the coil 1 ya ƙara amma current through the coil 2 ya ƙara.
Idan current through the coil 1 ya ƙara, magnetic field tana ƙara kuma magnetic needle tana ƙara zuwa baya showing the increment in the frequency. Similar action will takes if decrease the frequency but in this the pointer will moves towards the left side.
