verifi cation. 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. Terminals: 6 bnc connectors for standard values One triaxial output which is common for all 6 standards One fi ve-way binding post for guard with shorting link for connection to ground, and one ground post electrically connected to case Environmental: Operating 23°C ± 3°C Humidity: 30 to 60 % RH non-condensing Dimensions: 20 cm W x 11 cm H x 5.7 cm D (7.55" W x 4.38" H x 2.24" D) Weight: 2.4 kg (3.5 lbs), nominal Custom resistance values are available upon request
