Description

For measuring of capacity with ratio of R1 & series dial of R2 and one variable capacitor with audio oscillator, Air & dielectric capacitor and head phone Schering bridge kit: measurement of small capacitor A plug type resistance bar having 10, 20, 50, 100, 200, 500, 1000, 2000& 5000 ohms is connected in series with 4 decade dials of 0.1, 1, 10 & 100 ohms. A Variable capacitor with calibrated dial is connected in parallel with the four dial decade dials. A four dial capacitance box over the range of 0.001, 0.01, 0.1 & 1x 10 mfd is included in the circuit with working manual but with oscillator & head phone.
