2-4
Connections
Remote PreAmp triax connectors
The electrical configuration of each triax connector is shown in Figure 2-1A. The center
conductor of the connector (and triax cable) is HI (input/output or sense), and the inner shield
is cable guard. The outer shield (shell) of each triax connector is input/output LO.
NOTE
The 6430-322-1A triax cable (which is a supplied accessory) is terminated with a
triax connector on one end and booted alligator clips on the other end. (See Figure
2-1B.) When connected to the Remote PreAmp, the alligator clip with the red boot is
HI, the one with the black boot is GUARD and the one with the green boot is LO.
The outer shells of the triax connectors are connected to Input/Output LO. Therefore, for
floating source-measure operations, a voltage potential will be present on the shells of the triax
connectors. Even with the output of the SourceMeter off, voltage could be applied from the
external test circuit. As a general rule, do not touch the triax cables while any power is present.
WARNING
To prevent injury from electric shock, DO NOT touch the triax cables of
the Remote PreAmp while the SourceMeter is turned on or any external
source is turned on.
