Resistance Transfer Decade.

SR1030 Resistance transfer standard. Values 1Ω , 10Ω , 100Ω , 1 KΩ , 10 KΩ and 100 KΩ.
SR1030 Resistance transfer standards consist of 12 equal steps.
These steps are available in increments of 1 ohm (SR1030-1), 10 ohms (SR1030-10), 100 ohms
(SR1030-100), 1kohms (SR1030-1k), 10kohms (SR1030-10k) and 100kohms (SR1030-100k).
The Model SR1030 provides four-terminal connections for each step or for series and parallel combinations
of these resistance steps using the optional Series-Parallel (SPC102), Parallel Compensation Networks
(PC101) and shorting bars (SB103).
This improves power dissipation, stability and errors due to variance in temperature.
The SR1010 and SR1030 are used for the same applications and are alike in configuration.
The SR1030 differs from the SR1010 in that it is specially sealed, and values below 100KΩ are filled with
oil to improve changes due to thermal variations.
