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.
Description:
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
