With the power off, connect the digital multimeter and calibration standard to the
Model 6430 mainframe and Remote PreAmp as shown in Figure 18-7. (Connect the
mainframe INPUT/OUTPUT HI and LO jacks to DMM INPUT HI and LO respec-
tively. Connect the PreAmp IN/OUT HIGH jack directly to the Model 5156 OUTPUT
jack, and connect the BNC shorting cap to the 100GΩ resistance jack. Also be sure to
remove the link between the Model 5156 SHIELD and CHASSIS jacks.)
