3.19.1 Remote sense compensation functions
Under CC, CV, CR or CW mode, if the load consumes large current, a large
voltage drop will be detected in connection line between tested instrument and
load terminal. To ensure measurement accuracy, a remote sense measurement
terminal is provided at load rear board to compensate voltage drop lost in wire.
Remote sense operation: SENSE (+) and SENSE (-) are remote input
terminals. To avoid voltage drop caused by long input wire of load, the remote
sense allows direct measurement at input terminal source so as to improve
measurement accuracy.
Before using the remote sense measurement function, the user must set the
load in remote sense measurement mode.
Setting procedures:
Press [Shift] + 6 to enter menu. Move Left/Right key and select Remote-Sense.
Press [Enter] key and select ON to start Sense function.
