Features
Diverse lineup of products
A diverse lineup of products is available for the various
combinations of test required in production lines to
accommodate a variety of needs. Tests can be performed in accordance with the requirements of safety
and electrical standards and ordinances such as IEC,
EN, BS, VDE, UL, CSA, GB, and JIS.
Dielectric breakdown detection sensitivity settings
Safety standards define that corona discharge and partial discharge are not dielectric breakdown. This product
allows you to adjust the detection sensitivity of EUT’s
dielectric breakdown during withstanding voltage testing
to support a wide range of settings from those that do
not detect corona discharge or partial discharge to those
that do. Failure analysis that were not possible with previous Kikusui withstanding voltage testers is now possible.
Support for AC/DC earth continuity test up to 40 A
(TOS9302, TOS9303, TOS9303LC only)
The newly developed amplifier a broad range of tests
from AC earth continuity test of general home electric
appliances to DC earth continuity test of EV-PV systems.

Risk of electric shock.
• Do not use the product in a poorly ventilated location.
The product uses forced air cooling. It sucks air through
the inlet holes on its right and left panels and expels air
through its rear panel. Secure adequate space around
the product’s inlet and outlet holes to prevent the possibility of fire caused by accumulation of heat.
Allow at least 20 cm of space between the air inlet/outlet
and the wall (or obstacles). Be careful not to block the
air inlet and outlet when rack mounting the product.
Hot air (approximately 20 °C, 68 °F, hotter than the
ambient temperature) is expelled from the outlet holes.
Do not place objects that are affected by heat near the
air outlet.

Safety Precautions for Testing
WARNING
Lighting of the DANGER LED
The DANGER LED lights when the product is in any of the following conditions.
• At power on
• When a test is running
• When high voltage is being output
• When voltage remains at the output terminals
• When supply voltage is being supplied to the EUT (TOS9303LC only)
Check whether the DANGER LED lights at power on. If it does not, stop using the product, and contact
your Kikusui agent or distributor.
Test Precautions
Pre-test precautions
Risk of electric shock. In a AC withstanding voltage test, the TOS93 series generates a
maximum voltage of 5.0 kVac. In a DC withstanding voltage test, the TOS9301,
TOS9303, and TOS9303LC generate a maximum voltage of 7.2 kVdc. Handling the
product improperly may lead to a fatal accident. To prevent accidents, strictly follow
the precautions and always pay the utmost attention to safety concerns when you
operate the product.
Check the following items before you start testing, and always follow the precautions.
• The power cord is connected to a properly grounded outlet.
• There is no damage such as tears or breaks in the test lead insulation.
• When the POWER switch is turned on, the DANGER LED lights.
• While the DANGER LED is lit, do not touch the items that are charged to a high voltage: the EUT,
the test leads, and the areas near the output terminals.
• When the DANGER LED is lit, do not turn the POWER switch off except in an emergency.

Risk of electric shock.
• While the DANGER LED is lit, it is dangerous to touch the items that are charged to
a high voltage: the EUT, the test leads, the probes, and the areas near the output terminals.
• The alligator clip vinyl insulation of the supplied tests do not have dielectric
strength. Never touch these while the DANGER LED is lit.
• When performing a withstanding voltage test, be sure to wear rubber gloves for
electrical work. If obtaining these gloves is difficult, contact your Kikusui agent or
distributor.
During testing, the DANGER LED lights, and the display shows “TEST.” Be careful because high voltage
may be being output when the DANGER LED is lit.
Safety Precautions for Testing | Test Precautions
Precautions when setting test conditions

following items to ensure safety.
• The DANGER LED is off.
• The voltmeter is displaying “0.”
TOS93 Series User’s Manual 19
Safety Precautions for Testing
WARNING
Precautions after Output Has Been Turned Off
Risk of electric shock.
• For a while after the output has been turned off, do not touch the items that have
been charged to a high voltage, such as the EUT, the test leads, the test probes, and
the areas near the output terminals.
• After the output has been turned off, the internal discharge circuit goes into operation and discharges the output voltage. During testing and before this discharge
completes, do not disconnect the tester from the EUT.
The EUT, test leads, test probes, and the area around the output terminals are all charged to a high voltage. After the output has been turned off, be sure to check the following before you touch the items that
have been charged to a high voltage.
• The DANGER LED is off.
• “RISE,” “TEST,” or “FALL” is not shown on the display.
• The voltmeter is displaying “0.”
If you will not use the product for some time or if the operator will be away from the product, be sure to turn
the POWER switch off.
Estimated discharge time
The time required to discharge the built-up electrical charge varies according to the test voltage and the
properties of the EUT.
The time that this product requires to discharge the voltage from its internal capacitors down to 30 V is as
follows:
• When an EUT is not connected: 16 ms for a DCW test, 1.5 ms for an IR test
• When an EUT with a input capacitance of 0.05 μF is connected: 50 ms for a DCW test, 6 ms for an IR
test

Examples of how to connect test leads to the EUT
Reducing the effect of noise
Electronic devices in the surrounding area may malfunction due to the effect of noise produced by short
circuits across outputs or a dielectric breakdown of the EUT. To reduce the effect of noise, connect a toroidal core or a resistor of approximately 470 Ω between the tips of the high- and low-voltage test leads and
the EUT. Connect the toroidal core or resistor as close to the EUT as possible.
If you are connecting a toroidal core, it is effective to wrap the test leads two to three times around a type
of core that can be snapped on and that is often used with power cords. This type of core is usually
approximately 20 mm in diameter.
If you are connecting a resistor, pay close attention to the power rating of the resistor. When the upper limit
is 10 mA or less, connect a resistor of approximately 470 Ω (3 W, 30 kV impulse withstanding voltage).
Because connecting the resistor causes the voltage to fall, the voltage that is actually applied to the EUT is
slightly lower than the voltage that is generated from the product’s output terminals (when a 10 mA current
flows, the voltage falls approximately 10 V).
These methods are extremely useful in reducing the effect of noise.
