Standard Description Description GR General Radio IET 1615-A Capacitance Bridge Features: Accurate and precision measurements of capacitance and dissipation factor Measurement of circuit capacitance Dielectric measurements Inter-comparison of capacitance standards diff ering in magnitude by as much as 1000:1 10-5 pF to 11.1 µF, 2- or 3- terminal 0.01% accuracy, 1 ppm resolution Lever balance, in-line readout Reads dissipation factor or conductance 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 good condition, tested and working. Note: this is a passive (unpowered) instrument which requires a signal source such as a GR 1311A (not included) and an AC volt meter/tuned null detector such as a GR 1232A (not included). Some discoloration/blemish on front panel is evident. Instruction manual available here.
