  • Notes

  • The Wayne Kerr B224 is a manually operated bridge, the resistive and reactive terms being independently set to a null indicated on the meter.

    The bridge has ten-decade ranges and can be used to measure any component or complex impedance. Transformer ratio arms are used to cover a very wide range of measurements using a minimum number of standards set digitally. The three-terminal facility provided by this type of bridge enables small values of capacitance or high values of resistance to be measured at the end of long lengths of cable. Components can also be effectively isolated electrically from a complex network allowing individual measurements to be made without disconnection from the circuit being necessary.

    A rechargeable battery is fitted in order to make the instrument portable.
