Resistance Switching Transfer.

SR1050 High Resistance Switching transfer standard. Standard Values 1 and 10MΩ/step.
SR1050 High Resistance Switching transfer standards consist of 11 equal steps.
These steps are available in increments of 1Mohm, (SR1050-1M) and 10Mohms, (SR1050-10M).
The Model SR1050 provides a three terminal connection for each step or for a series of resistance steps.
Specially designed lever switches separate each resistor from the others.
This allows the standard to be configured in series, parallel, series-parallel, or separately without the use
of external shorting bars.
