The 1615-A Capacitance Bridge brings to the measurement of capacitance, the inter-comparison of standard, and to the measurement of dielectric properties an unusual degree of accuracy, precision, range, and convenience. High accuracy is achieved through the use of precisely wound transformer ratio arms and highly stable standards fabricated from Invar and hermetically sealed in dry nitrogen. For calibration these standards can be inter-compared.
Two- or Three- Terminal Connection:
Accurate three-terminal measurements can be made even in the presence of capacitance to ground as large as 1 µF, as might be encountered with the unknown connected by means of long cables. The bridge has the necessary internal shielding to permit one terminal of the unknown capacitor to be directly grounded, so that true two-terminal and three-terminal measurements can both be made over the whole capacitance range.
The item is in excellent condition, tested and working.
