5.1 Remote Sensing
Remote sensing is used to counteract the eect of lead resistance. For example, if you connect a power supply to the DC
Load, the voltage at the power supply’s terminals will not be the same as the voltage at the DC Load’s terminals if there
is a current owing because of the nite resistance from the wires. Using remote sensing, you can sense the voltage at
the power supply’s terminals, eectively removing the eect of the voltage drop in the connection wire.
Connect the “+” and “-” terminals at the rear of the unit to the power source.
Note:To reduce interference, twist the sense lines together and run together with the wires connecting the load to
the source.
Note:When using remote sensing, the power displayed by the instrument includes both the power dissipated inside
the instrument and the power dissipated in the leads from the power supply to the DC Load’s input terminals.
