Inspection and Installation
2.5 Connecting the Device Under Test (DUT)
The instrument supports two connection methods between power supply and
DUT: Local measurement and Remote sensing.
• Local measurement：The voltage sensed by the instrument is the voltage at
the output terminal of the instrument.
• Remote sensing：The voltage sensed by the instrument is the voltage at the
terminal of the remote object under test.
Precautions
To prevent electric shock and damage to the instrument, observe the following
precautions.
• Before connecting DUT, be sure to switch off the power supply.
Power switch is in Off position, otherwise touching the output ter-
minals on the rear panel may result in personal injury or death due
to electric shock.
• To avoid electrical shock, before testing, please make sure the rat-
ing values of the testing cables, and do not measure the current
that higher than the rating value. All test cables shall be capable of
withstanding the maximum short circuit output current of the
power supply without causing overheat.
• If several loads are provided, each pair of load wires shall safely
withstand the rated short circuit output current of the power supply
under full load.
• During wiring, check that the anode and cathode of the test lines
are properly and tightly connected; anode On and cathode Off are
prohibited.
Specification
Test cables are not standard accessories for the instrument. Please select op-
tional red and black test cables for individual sales based on the maximum cur-
rent value. For specifications of test cables and maximum current values, refer
to A.1 Specifications of Red and Black Test Cables for more information.
Connecting the DUT (Local Measurement)
The connection diagram and steps of local sensing are as follows:
