|Marconi TF 1313A Interface|
|Description||O.l % Universal Bridge|
TF 1313A is a general-purpose impedance bridge with one tenth per cent measurement accuracy over a wide range of inductance, capacitance, and resistance values. It offers exceptional discrimination and resettability, wide-range loss balancing, and facilities for using an external oscillator and detector. The single direct-reading dial used for L, C, and R measurements has coarse aiid fine concentric controls; the coarse one moves in 1% steps and the fine gives continuously variable interpolation between steps. The variable and non-linear sensitivity of the detector facilitates easy measurement of completely unknown components. An external audio oscillator can be plugged in where L and C measurements are required at frequencies other than the internal 1 and 10kc/s; the detector output is available externally to allow an oscilloscope or headphones to be used for balance indication. This bridge can be used for precision evaluation of resistance, capacitance and inductance, for measuring the dissipation factor of capacitors and Q of inductors, and for quickly identifying unknown components. Measurements on high-loss components are made easier by the low D and Q ranges of the loss balance control and the relative independence between the adjustment of the main and loss balance controls. Its high discrimination and resettability make it particularly suitable for comparative measurements such as checking the difference between an unknown and a standard component. Measurements on inductors carrying d. c. can be made by using Adaptor TypeTM6113, which is available as an optional accessory, while an external d. c. supply can be connected direct for polarizing capacitors.
