Used for measuring unknown resistance of moderate ranges by comparison method. The Bridge is a self contained unit with built-in Galvanometers & Battery. The bridge has got the following main features.
Measuring Range: 0.001 Ohm to 11.11 Megohms, Housed in a nice wooden box with carrying handle.
Series Arm: It contains four decade dials of 1, 10, 100 & 1000 Ohms
Ratio Arm: It is in single dial giving multiple rations of 0.001, 0.01, 1,10, 100 & 1000 Ohms.
BATTERY: Built in 4.5 Volts, having 3 Nos. Torch Cells, fitted in the battery compartment at one side of the box with a removable lid.
GALVANOMETER: Built-in with antiparallex mirror, knife edge pointer having sensitivity of 100 mA per scale div. Provision for connecting external Galvanometer.
Switches: Two D.P.D.T. switches are provided to connect internal or external Galvanometer & Battery when desired.
Keys: Two press keys are fitted on the panel to connect the battery & galvanometer into the circuit.
Terminals: 6 terminals are provided on the panel for connecting experimental Resistance, external Galvanometer. CONSTANTAN COILS Calibrated to within +0.1%
Provided with operating instructions.
Also available with Manganin Coils. Calibrated to with + 0.05%
