NOTE
Connection drawings in this manual are shown using the Remote PreAmp. If not
using the Remote PreAmp, make connections to the equivalent banana jack termi-
nals on the rear panel of the mainframe.
WARNING
To prevent injury from electric shock, DO NOT touch the triax cables of
the Remote PreAmp while the SourceMeter is turned on or is connected to
an external source that is turned on.
CAUTION
When using the Remote PreAmp, DO NOT use the INPUT/OUTPUT HI
and 4-WIRE SENSE HI banana jacks on the mainframe. Using these ter-
minals while the Remote PreAmp is plugged in will result in errors and/or
noise, and possible damage to the Remote Amplifier.
Sensing methods
Basic source-measure operations are performed using either 2-wire sense connections
(Figure 2-2) or 4-wire sense connections (Figure 2-3). See Section 4,
Ohms sensing
for
additional information.

WARNING Guard is at the same voltage level as
input/output high. Therefore, if a
hazardous voltage (
≥
42V peak) is
present on input/output high, it is also
present on the guard terminals of the
Remote PreAmp and mainframe.
