Voltage Sense Input Terminals
When the voltage sense mode is set to internal,
the DC load module senses the DC at the input
terminals of the DC load. Any voltage drop
between the EUT and the load module across the
load wires is not detected so the actual voltage at
the EUT may be somewhat higher than is sensed
by the load. For low current applications, the
voltage drop may be negligible. Figure 7-2 shows
the load connection with internal sense mode.
To measure the UUT output DC voltage directly
at the UUT terminals, external voltage sense
mode must be used. The external voltage sense
terminals are provided on the front panel of the
load module for this purpose. Refer to Figure
7-3 for details on the V Sense terminal location
and polarity. This mode is recommended for
higher current applications or when voltage
precision is important.
