  • R. F. bridge B 601

    This instrument measures a wide range of capacity, resistance, and inductance, as well as impedances, such as lines, which may be floating, unbalanced, or balanced with the centre point earthed. It is capable of selecting the capacity between any pair of electrodes in a three-electrode condenser.
    Capacity and resistance are examined as a parallel combination and, as the C and R multipliers are selected by separate switches, the loss factor for coils and condensers can be determined over a wide range.
    The circuit is a development by Wayne Kerr of an original design by the B.B.C. Research Department.

    Specifications:

    • Capacity: 0.01 pf. to 20.000 pf. in five ranges.
    • Resistance: 10 ohms to 10 megohms, in six ranges.
    • Inductance values which will resonate the above capacities between 15 kHz and 5 MHz.
    • Direct reading accuracy is constant to within 1 %, up to 3 MHz. and may fall to 2% at 5 MHz.

    The R. F. bridge B 601 holds the distinction of being the first instrument manufactured by Wayne Kerr Laboratories, Ltd. Debuting in August 1946, it was initially advertised with a working range of 10 kHz to 5 MHz (Wireless World, August 1946, p. 268). However, by November 1947, the advertised range had shifted to 15 kHz to 5 MHz.
    It remains unclear whether this change reflected a typographical error or the introduction of a revised version of the instrument.

    It was a popular instrument sold through to the late 1960s.
