Self Inductance Anderson Bridge
Product Code : JA-SI-8065
The Self Inductance Anderson Bridge (SKU JA-SI-8065) measures the self inductance of a coil by the Anderson method, which balances inductance against a capacitor and resistances. Everything is on one Bakelite board: a 1 kHz sine wave source with two output sockets and an amplitude indicating lamp, a built-in null detector with digital display, the decade dials of the bridge arms and four unknown inductances. The circuit layout is spread out with 4 mm sockets for the connections.
