They are used to make very high accuracy resistance transfers. A set of 9350's can be used to build up from a Thomas type 1 Ohm standard up to 1 MegOhm. Applications for the 9350 include performing linearity and ratio accuracy tests on resistance bridges such as the Guildline 6622A, 6675A and 9975 bridges. At specific values the 9350 can also be used as a standard resistor. For example, by a series parallel combination, a 25 ohm standard resistor can be set up which would enable measurements with PRT's. The 9350 contains 10 nominally equal resistors permanently connected in series by specially designed true four terminal junctions. Groups of resistors can be connected in parallel or series parallel combinations to 9350 FEATURES obtain many values independent of the terminal blocks and paralleling connectors to better than 5 parts in 10-8. Transfer accuracy 0.05 ppm The 9350 (Hamon Type) Resistance Transfer 5 versions: Standard is used to make very high accuracy 10k to 1M, 1k to 100k resistance transfers. 100 to 10k, 10 to 1k 1 to 100 The various combinations are selected by a tapered plug 10 equal value precision resistors arrangement. This method has eliminated the use of mercury wetted shorting bars common in earlier Unique four terminal junctions generation Hamon Type Resistance Transfer Standards. Special tapered plug design The tapered plugs have a taper angle of a critical avoids use of mercury shorting dimension which, while maintaining a low impedance, bars allows the plugs to be easily removed or inserted. The A Multi-value Standard Resistor taper angle is also designed to prevent cold welding of the copper. A convenient storage area is provided for Low maintenance the tapered plugs not in use. |
