REMOTE SENSE :
Remote sensing is accomplished by connecting the load
to remote sensing terminals on the front panel and
selecting the remote mode by pressing the "SENSE
MODE" push switch. The leads from the sensing
(+S and -S) terminals to the load will carry much less
current than the load leads and it is not required that these
leads be heavy as the load leads. However they must be
twisted or shielded to minimize noise pickup.
For reasonable load lengths remote sensing greatly
improves the performance of the supply. However, if
the load is located at a considerable distance from the
supply, added precautions must be observed to obtain
satisfactory operation. Notice that the voltage drop in the
leads subtracts directly from the available output voltage
and also reduces the amplitude of the feedback error
signals that are developed within the unit. Because of
these factors it is recommended that the drop in each
load lead does not exceed 0.5V.
