Shunt-Type Ohmmeter

When Rx = 0, no current in meter.When Rx = ∞, entire current flows through the meter.Proper selection of R1 gives full-scale deflection on open circuit.

DYNAMOMETER TYPE INSTRUMENTSFor both ac & dc measurements

• These instruments are similar to the permanentmagnet type instruments, except that the permanentmagnet is replaced by a fixed coil.

• The coil is divided into two halves, connected inseries with the moving coil.

• The two halves of the coil are placed close togetherand parallel to each other to provide uniform fieldwithin the range of the movement of moving coil.
