Electrometer Calibration Standard SCR-5156-IET

SCR-5156-IET Electrometer Calibration Standard


  • 4 resistance standards 100 MΩ to 100 GΩ
  • 1 nF and 100 nF capacitors for charge calibration
  • Accuracy: 1%
  • Accredited calibration certificate
  • Excellent replacement for Keithley 5156
  • For use with the Keithley 6517 and other electrometers
  • Custom resistance values are available upon requestHigh-performance, electrometer calibration standard for use with the Keithley 6517 and other electrometers.



The SCR-5156-IET contains 4 resistors and 2 capacitors as recommended in the Keithley 6517 Service Manual for current and coulombs verification.

The metal housing provides shielding from noise and a shorting link is provided to connect guard and ground when required.

The output of the SCR-5156-IET is a triaxial connector for direct connection to the Keithley 6517.

There are 6 bnc connectors for each of the internal standards.

The calibrated value of each standard is located on the front panel.

Custom resistance values are available upon request
