Schering Bridge
Product Code : JA-SI-8080
The Schering Bridge (SKU JA-SI-8080) measures unknown capacitance, together with the loss in the capacitor, against a fixed standard capacitor C2 of 0.001 mfd. The ratio arms R1 and R2 have steps of 1, 10, 100 and 1000 ohm, R is a decade dial of x1 ohm, and C1 is a two-decade dial of x0.001 and x0.01 mfd. A 1 kHz sine source with two output sockets and an amplitude indicating lamp and a digital null detector are built in. Five unknowns on the board are selected by a rotary switch.
