(1) Remote sense cable
Be sure to connect remote sensing cables
It is necessary to connect remote sensing cables properly when in EXT sensing mode
(you can select EXTernal sensing or INTernal sensing by switching a button in rear
panel of main unit). Use such as shielded cable or twisted cables. Pay great attention on
its polarity.
If a remote sense cable is not used (opened), it would cause an error in voltage
measurement at load terminal and measurement in CR, CV, CP modes requiring
reference voltage.
・ Powers OFF a TARGET DEVICE first before you connect cable to the TARGET
DEVICE. In a case of using remote-sensing cable, you must switch a selecting
button (it‟s in rear panel in main unit) to EXTernal sensing. When you don‟t use
remote-sensing cable, you have better to select INTernal sensing. If you don‟t
have a properly setting, you can‟t measure a correct value and you are also
trouble in load setting and power protection.
This product has a protection resister against a reverse connection between remote sense and
load terminals. So as for the voltage, measurement at the load terminal, measured value may
be lower than actual value due to the protection resister. There is no protection resister at the
remote sense terminals.
