This training board is designed specifically for measuring the inductance of a coil by the Anderson bridge method. It includes an audio amplifier with speaker for null detection (instead of a headphone) and a 1 kHz sine-wave oscillator (instead of an external decade audio-frequency generator). The board is completely self-contained and requires no other apparatus, and practical experience on it carries great educational value for science and engineering students.

Objective: to measure the inductance of a given coil by the Anderson bridge method.

The board includes the following built-in parts:
1. Anderson bridge circuit with arm values
2. Potentiometer for varying one arm
3. Three different inductance values
4. Potentiometer with calibrated dial
5. Five capacitors selected by a band switch
6. Audio amplifier with IC-regulated power supply
7. 1 kHz sine-wave oscillator with IC-regulated power supply
8. Speaker
9. Mains ON/OFF switch, fuse and jewel light

It comes with an adequate number of stackable patch cords (4/2 mm spring-loaded plugs, 1/2 metre long), detailed operating instructions covering objective, theory, design procedures, report suggestions and book references, and operates on 230 V ±10% at 50 Hz AC mains.
