Model SR1010 - Resistance Transfer Standard (1 to 100k Ohm/Step)

DESCRIPTION: The SR1010 transfer standard consists of 12 equal resistance steps. These steps are available in increments of 1 (SR1010-1), 10 (SR1010-10), 100 (SR1010-100), 1k (SR1010-1k), 10k (SR1010-10k) and 100k (SR1010-100k). The Model SR1010 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.

FEATURES:

  • Initial Accuracy... ± 20PPM of nominal value matched within 10PPM
  • Transfer Accuracy... ± (1PPM + 0.1u at parallel value) for 100:1
  • Transfer Accuracy... ± (1PPM + 1u at series parallel value) for 10:1
  • Long Term Accuracy... ± 50PPM of nominal value
  • Calibration Accuracy... ± 10PPM
  • 1 year warranty

APPLICATIONS:

  • Calibration of Working Standards and Precision Resistance Measuring Systems
  • Reference Voltage Divider
  • Used to transfer NIST traceability to different values of Resistance

Model SR1030 - Resistance Transfer Standard (1 to 100k Ohm/Step)

DESCRIPTION: Model SR1030 transfer standards consist of 12 equal steps. These steps are available in increments of 1 (SR1030-1), 10 (SR1030-10), 100 (SR1030-100), 1k (SR1030-1k), 10k (SR1030-10k) and 100k (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 100KW are filled with oil to improve changes due to thermal variations.

FEATURES:

  • Initial Accuracy... ± 20PPM of nominal value matched within 10PPM
  • Transfer Accuracy... ± (1PPM + 0.1u at parallel value) for 100:1
  • Transfer Accuracy... ± (1PPM + 1u at series parallel value) for 10:1
  • Long Term Accuracy... ± 50PPM of nominal value
  • Calibration Accuracy... ± 10PPM
  • 1 year warranty

APPLICATIONS:

  • Calibration of Working Standards and Precision Resistance Measuring Systems
  • Reference Voltage Divider
  • Used to transfer NIST traceability to different values of Resistance

Model SR1050 - High Resistance, Switching Transfer Standard (100k to 110M Ohm)

DESCRIPTION: Each of the SR1050 transfer standards consist of 11 equal steps. These steps are available in increments of 1M, (SR1050-1M) and 10M, (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.

FEATURES:

  • Transfer Accuracy... ± 2PPM (Typical Short-term Repeatability)
  • 1M Calibration Accuracy... ± 10PPM
  • 10 M Calibration Accuracy... ± 15PPM
  • Leakage Resistance... > 10¹³

APPLICATIONS:

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