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.

• Transfer Accuracy... ± 2PPM (Typical Short-term Repeatability)

• 1MΩ Calibration Accuracy... ± 10PPM

• Leakage Resistance... > 10¹³ Ω

APPLICATIONS:
Calibration of Working Standards and Precision Resistance Measuring Systems
Used to transfer NIST traceability to different values of Resistance
