Specification
Test cables are not standard accessories for the instrument. Please select
optional test cables for individual sales based on your requirements.
Connecting the interlock circuit
The IT2801 model of the IT2800 series SMU has a maximum output voltage of
up to 1000VDC. To maximize the safety of the DUT as well as the user's
personal safety, the IT2800 provides an interlock function to prevent the user
from receiving an electrical shock from high voltages over ±42VDC. If the Digital
I/O interlock terminal (Pin21 and Pin22) is open, IT2800 cannot apply a high
voltage. The IT2800 can only output the rated voltage after the Interlock
terminals (Pin21 and Pin22) are shorted.
Before connecting test cables, be sure to switch off the power
supply. Power switch is in Off position, otherwise touching the
output terminals 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 cable
end is not connected when connecting or disassembling the test
cable. When the test cable end is connected with battery, short
circuit may cause severe accident.
Please check that the test cables can withstand maximum current.
During wiring, check that the anode and cathode of the test cables
are properly and tightly connected; anode ON and cathode OFF are
prohibited.
