Wein Series Resistance Bridge
Product Code : JA-SI-8069
The Wein Series Resistance Bridge (SKU JA-SI-8069), the Wien series bridge of AC practicals, is built on one Bakelite board with its own 1 kHz sine wave source, which has two output sockets and an amplitude indicating lamp. A null detector with digital display is built in, and the listing notes that a small speaker can be used instead. Five unknown values are fitted on the panel and selected with a rotary switch, and the connections are made at 4 mm sockets on a spread-out layout.
