More info on the 9350

Resistance standard

Guildline Instrument model 9350 are hamon type resistance transfer standards.

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.
