Used for measuring self inductance. Two ratio dials of 1000, 100 & 10 ohms each are connected to 3 decade dials of the same values. One of the ratio arms is shunted with capacitance arranged in 3 decade dials over the range of 0 to 1.11 Mfd. The fourth arm is having 3 more decade dials of 0.1, 1, & 10 ohms with one experimental inductance. Accuracy of calibrations is ± 0.1%. Complete with inbuilt audio oscillator, headphone and working instructions
