  • Notes
  • The Yokogawa-Hewlett-Packard (YHP) Model 4260A Universal Bridge was the first product of the corporation's agreement (1963) of HP and Yokogawa Electric Works, Ltd., of Tokyo.
    The unit makes fast, easy measurements of resistance (R) , capacitance (C), inductance (L), capacitor dissipation factor (D), or inductance quality factor (Q). The instrument includes five bridge circuits, selected by the FUNCTION switch, as well as the detector and 1 kHz oscillator necessary for dc and ac measurements. For measurements at frequencies other than 1 kHz, an external oscillator must be used.
    Front panel controls select the measurement function and range, with R, L, and C values displayed with four-digit resolution on an in-line, digital counter. Q and D values are displayed on a dial with a red hairline indicating the measured value. The auto-balance circuit and an easy-to-read meter reduce the time required for measuring low Q or high D components.
    Correct decimal point location is automatic and direction lights indicate which way the CRL control should be rotated for the measurement.
    Capacitance 1 pF to 1000 μF in 7 ranges.

    Inductance 1 μH to 1000 H in 7 ranges

    Resistance 10 mΩ to 10 MΩ in 7 ranges.
    Made in Tokyo.
