tests
With the power off, connect the digital multimeter to the Remote PreAmp IN/OUT
HIGH jack as shown in Figure 18-5. (Connect the IN/OUT HIGH jack to the DMM
INPUT HI and LO jacks using the adapters and coax cable as shown.)
Use the type of triax-to-BNC adapter that connects triax shell to BNC shell. Also be
sure that the cable shield is connected to DMM INPUT LO.
Select the SourceMeter 10µA measurement range.
Select the multimeter DC volts measuring function.
Press the Model 6430 SOURCE V key to source voltage, and make sure the source out-
put is turned on.
