WARNING
●In measurement with this instrument, high voltage may be
applied and high current may be supplied. Always close the
cover before measurement after setting the DUT (Device
Under Test) on the Test Fixture. Do not open the cover of
the Test Fixture during measurement.
High voltage (max. 5 kV) may be applied and high current (max. 2 kA) may be supplied to the terminal
to which the DUT is mounted. To prevent danger, if the cover of the Test Fixture is not closed, no
voltage and current can be supplied to the terminal and no power can be applied to the DUT. And, do
not remodel the switch for power supply shutoff or do not open the cover during measurement. If not,
electric shock may be caused.
When it is detected that the cover of the Test Fixture is opened during measurement, the supply of
voltage and current to the terminals is immediately cut off, and the energization of the DUT is
stopped. For your safety, do not open the cover during measurement.
●After measurement, the DUT may be charged. Do not
touch the DUT until discharging it through the grounding
rod and confirming the safety.
Touching a charged or generated measurement DUT may cause electric shock or burns. Take
measures such as using gloves and leaving it for a sufficient time.
●When using anything other than the test wire lead or
small crocodile that comes with the Test Fixture, pay
attention to the withstand voltage and allowable cur-
rent.
If the measurement is performed without considering the measurement potential, cable outer insula-
tion, and GND cable outer insulation rating, it may cause a fire or malfunction. Use the specified cable
that comes with the Test Fixture according to the measurement content.
●If you notice smoke, abnormal smell or abnormal sound,
immediately take measures below and unplug the power
plug from the power outlet.
(1) Turn off the standby switch of the CS-8000 Series.
(2) Turn off the main power switch of the CS-8000 Series.
(3) Unplug the power plug of the instrument and CS-8000 Series from the power outlet.
Continued use under these circumstances may result in electric shock or fire. After taking measures
above, contact IWATSU or our sales distributors for repair. Repairing the instrument by yourself is
very dangerous. Do not attempt to repair the instrument under any circumstances.

WARNING (Continued)
●Do not use in an environment with explosive gases.
This may result in explosion.
●Make sure no water gets on or inside the instrument.
Failure to observe this precaution may result in electric shock or fire. If water gets on or inside the unit,
after making the power switch a standby, and pulling out the power plug from the power outlet, contact
IWATSU or our sales distributors for repair.
●Do not touch the plug of the power cord if your hands are
wet.
This may result in electric shock.
●Do not place this instrument on an unstable place such as
a shaky stand or inclined place.
Letting this instrument fall or topple down may result in electric shock, fire or injury. If this instrument
falls or its cover is damaged, after making the power switch a standby, and pulling out the power plug
from the power outlet, contact IWATSU or our sales distributors for repair.
●Surely insert the power plug into the power outlet after
checking that any dust is not sticking to the power
plug. Additionally, disconnect the power plug or power
adaptor from the power outlet once every six months to
one year, and inspect and/or clean the power plug.
If the power plug is contaminated, this may cause an electric shock, a fire, or a malfunction.
●Do not put any foreign objects, such as metallic or
flammable objects through the ventilation opening.
If any foreign object of metal and the combustible one, etc. is put through the ventilation opening, this
may result in electric shock, fire, and/or malfunction.
If any foreign object enters this instrument, after making the power switch a standby, and pulling out
the power plug from the power outlet, contact IWATSU or our sales distributors for repair.

Chapter 1 Overview
HC UNIT CS-200 Series Instruction Manual 1-1
Chapter 1 Overview
The development of semiconductor technology is remarkable and diverse, and the number of
equipment such as heavy electric power (electric power), home appliances, air conditioning,
and transportation that incorporate power devices such as inverters continues to increase, and
the technological progress is remarkable. In power electronics technology, we are moving from
the conventional pursuit of high efficiency of electric power to the one that tries to reduce the
energy density (make it compact) or that is eco-friendly. In the transportation industry such as
trains, the automobile industry, and power device manufacturers, the development of compo-
nents for eco-friendly instruments is rapidly expanding.
Inverter technology used in many electronic devices such as air conditioners, refrigerators,
elevators, trains, hybrid cars, solar power generation and wind power generation is a circuit
technology that is indispensable for energy saving. The importance of evaluating
next-generation power semiconductor devices such as SiC and GaN is increasing in order to
improve the efficiency of these energy uses.
The Curve Tracer CS-8000 Series was developed by further enhancing the Curve Tracer
CS-3000 Series and CS-5000 Series in order to evaluate power semiconductor devices in the
power electronics market.
The HC Unit CS-200 Series was developed as a large current unit for the Curve Tracer CS-8000
Series, and you can select and use a model that matches the current of the measurement range of the
Curve Tracer specifications and connection options.
1.1 Future
This instrument is a most-advanced device that can handle a maximum peak current of 2 kA. It can be used not
only for measuring the characteristics of large-current power devices such as the latest IGBTs and power
MOSFETs, but also for measuring the characteristics of various semiconductors such as transistors and diodes.
In the HV Unit CS-200 Series, there are three models: CS-205 / CS-210 / CS-220.
■CS-205
・Maximum measurement voltage up to 50 V is possible.
・maximum measurement current of 500 A is possible.
■CS-210
・Maximum measurement voltage up to 50 V is possible.
・Maximum measurement current up to 1 kA is possible.
■CS-220
・Maximum measurement voltage up to 50 V is possible.
Note: CS-220 is limited to 41 V only when the output setting is voltage and the 2 kA range is used.
・Maximum measurement current up to 2 kA is possible.

■Handling of the DUT
Set the large current measurement of the DUT by one of the following two methods.
Connect the connection terminal of the Test Fixture CS-322 and the terminal of the DUT directly to the
terminal of the Test Fixture with a test wire lead with a crocodile or an HV / HC cable.
Place a dedicated measurement panel for each DUT to be measured in place of the patch panel, and wire
directly between the patch panel connection and the measurement panel. Efficient measurement is possible
by preparing a measurement panel that allows the device to be measured to be securely connected and
easily attached and detached.
For the Test Fixture in which the DUT to be measured is set, close the cover before measuring.
