When the sense leads are disconnected, the power supply goes into the local sense
mode, as the V and S terminals are internally interconnected via resistors. Yet you are
strongly recommended to interconnect the V and S terminals with the straps if you
use the local sense mode, as open sense inputs are sensitive to noise. Moreover, the
output specifications are not guaranteed when the sense terminals are open.
Output modules with low voltage ratings may have less sense capability for output
voltages in the upper part of the voltage range, e.g. the 8V/15A module for the
sense range from 4V to 8V (see the Reference Manual, Appendix A).
For power supplies with a Front Connection Unit, the sense capability is reduced
with about 5mV/A per load lead.
