Connecting The Device Under Test (Dut) - Cal Power IT-M3400 Series User Manual

2.5 Connecting the Device Under Test (DUT)

The instrument supports two connection methods with DUT: Local
measurement and Remote sensing. The default test mode is local
measurement.
•
•
This series instrument include built-in circuit that connect or disconnect the ±
sense terminals from their corresponding ± output terminals. As shipped, the
sense terminals are internally connected to the output terminals. This is referred
to as Local measurement. If you need to use remote sensing, after making the
connection, be sure to turn the sense function on under system menu.
Precautions
To prevent electric shock and damage to the instrument, observe the following
precautions.

Local measurement: The sense voltage is measured from the output
terminals.
Remote sensing: The sense voltage is measured from DUT terminals.
Before connecting test cables, be sure to switch off the power supply.
Power switch is in Off position, otherwise touching the output terminals
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 rating
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.
To avoid battery short circuit, be sure to check that the test line end is
not connected when connecting or disassembling the test line. When the
test line end is connected with battery, short circuit may cause severe
accident.
During wiring, check that the anode and cathode of the test lines are
properly and tightly connected; anode ON and cathode OFF are
prohibited.
If you need to pull out the green output terminal, please lift it up and pull
it out, otherwise it will damage the instrument.
