1.2 Introduction and Features
This tester is used to perform earth continuity tests required for class-I devices for
various safety standards, including the IEC, EN, UL, VDE, BS, JIS, and the Electri-
cal Appliance and Material Control Law of Japan.
The tester must be used under the following conditions:
•Making test current constant
The test current for earth continuity tests has been made constant. This eliminates
the need to alter the test current, even if the resistance of the DUT (device under
test) changes.
•Safety output voltage
The constant current/constant voltage circuit provides fast response, preventing
generation of excessive output voltage even when output is interrupted during test-
ing. The tester complies with the limitations on no-load output voltages (6 V or
less,
12 V or less, and so on) required by many safety standards.

•Reduced cycle time
A test current is a constant current value set within approximately 100 ms.
Earth continuity tests can be conducted even at 1-second intervals. This enables
the instrument to perform tests in production lines that require reduced cycle
times.
•Compact and lightweight
A new high-efficiency power supply (achieving a power conversion efficiency of
65%) and large output (TOS6200A: 150 VA, TOS6210: 220 VA) makes possible a
tester that is remarkably compact and lightweight, about half the size and weight
of our conventional testers.
•Excellent measurement accuracy
The tester is equipped with an ohmmeter of +/-(2% of reading + 0.003 ) that cal-
culates resistance values based on measured current and voltage.
•Offset canceling function
The tester has an offset canceling function that cancels values for contact resis-
tance at alligator clip connections, the contact resistance of measuring leads in
measurements using two terminals, and other resistance components.
•Contact check function
The tester is provided with a contact check function that verifies the connection of
the DUT (by current detection) before initiating testing.
•Voltage judgment function
This function allows either a resistance value or a voltage drop value (voltage
between the SAMPLING terminals) to be selected as the reference value for judg-
ment criteria.
It also allows voltage drop value-based testing to be conducted, which is required
by safety standards such as UL 60950-1 and IEC 60950-1.
•Simple operations
Tester functions are fast and easily controlled, with an intuitive control method
that's easy to pick up, even for first-time users.
For example, test conditions are set simply by selecting an item displayed on the
LCD with the cursor keys and turning the rotary knob to set/select a value.
Any items you wish to set up can be assigned to the function keys.

TOS6200A/6210 General 1-5
•Stores up to 100 types of test conditions
The tester allows you to store and name up to 100 test conditions involving param-
eters such as test current, determined resistance value, and test time. For example,
you can store test conditions for a specific safety standard under the name of the
standard, or store test conditions under the name of the destination of the DUT.
When test conditions need to be modified due to changes in the destination of the
product or revised safety standards, you can recall a set of test conditions simply
by entering a memory number, making necessary modifications to the pre-existing
standard.
Assigning specific names allows test conditions to called up by name. This func-
tion is available through both the front panel and the remote control.
•Programming of test conditions
A combination of stored test conditions allows automatic execution of tests con-
sisting of several programs of up to 100 steps each.
Although the total number of steps is limited to 500, 100 types of programs can be
stored and recalled from the front panel or the remote control.
•GPIB and RS-232C interfaces
The tester is provided with standard GPIB and RS-232C interfaces. It is therefore
not necessary to buy additional GPIB and RS-232C boards.
An interface cable and PC or sequencer allows remote control of test conditions
such as test current, determined resistance value, and testing time. Measured val-
ues and test results can also be read back.
•Supplied test leads
The tester comes with alligator clip test leads, letting you start testing immedi-
ately.
•Memo function
The tester has a memo function that can store up to 20 characters per line on 3
lines, which can be used to store serial numbers, calibration dates, and/or com-
ments.

CAUTION

2-4 Installation and Preparation for Use TOS6200A/6210
2.3 Connecting the AC Power Cord
• This product is a piece of equipment that conforms to IEC Safety Class I
(equipment that has a protective conductor terminal). Be sure to earth
ground the product to prevent electric shock.
The product is grounded through the power cord ground wire. Connect the
protective conductor terminal to earth ground.
• Use the supplied power cord to connect to the AC line.
If the supplied power cord cannot be used because the rated voltage or the plug
shape is incompatible, have a qualified engineer replace it with an appropriate
power cord that is 3 m or less in length. If obtaining a power cord is difficult, con-
tact your Kikusui agent or distributor.
• The power cord with a plug can be used to disconnect the product from the AC
line in an emergency. Connect the plug to an easily accessible power outlet so that
the plug can be removed from the outlet at any time. Be sure to provide adequate
clearance around the power outlet.
•Do not use the supplied power cord for other devices.
This product is a piece of equipment that conforms to IEC Overvoltage Category II
(energy-consuming equipment that is supplied from a fixed installation).
Procedure
1. Check that the POWER switch is turned off.
2. Check whether the AC power line is compatible with the input rating of
the Tester.
The product can receive a nominal power supply voltage in the range of 85 Vac
to 250 Vac at a frequency of 47 Hz or 63 Hz.
The input voltage range is also indicated under LINE VOLTAGE RANGE on
the rear panel.
3. Connect the power cord to the rear-panel AC inlet, and then connect
the power plug to an outlet that has a ground terminal.

2.4 Connecting the Test Leads
• This product carries a maximum current flow of 30 A or 62A. Always check
to make sure that no connections are loose. Loose connection will result in
overheating of the OUTPUT terminals or the DUT (Device Under Test),
which may then result in burns or injury.
• Never connect the voltage measurement cable (thin wire) of the supplied
test leads or optional test probe to the OUTPUT terminals. The nominal
sectional area of this wire is inadequate for such currents, and burning
may result.
• This product carries a large current and consequently generates a strong
magnetic field. Make sure that no articles that may be affected by mag-
netic fields are located near the test leads or current output lines.
For example, images on a CRT positioned close by may be significantly
distorted.
2.4.1 Supplied Test Lead TL11-TOS/TL12-TOS
1. Remove the short-circuit bars connecting the OUTPUT and SAMPLING
terminals.
2. Connect the current output line on the crimp terminal side of the test
lead (black or white) to the LOW side of the OUTPUT terminals; con-
nect the voltage measurement line on the banana plug side to the LOW
side of the SAMPLING terminals. Check that the connections are
secure.
WARNING
CAUTION
TOS6200A
Take care not to get your finger
caught between the output
terminals when turning the knobs.
TOS6210

2-6 Installation and Preparation for Use TOS6200A/6210
3. Connect the current output line on the crimp terminal side of the test
lead (red) to the HIGH side of the OUTPUT terminals; connect the volt-
age measurement line on the banana plug side to the HIGH side of the
SAMPLING terminals. Check that the connections are secure.
• Improper terminal connections can result in inaccurate measurements and
burns or injury resulting from heat generated by contact resistance at the
terminals.
4. Connect the alligator clip of the test lead (black or white) to the protec-
tive conductor terminal of the DUT.
5. Connect the alligator clip of the test lead (red) to a test point of the DUT.
For details, see 2.4.6, "Connecting to the DUT”
• Make sure that the alligator clip connections are secure.
Improper connections may result in clip disconnection, causing sparking
and potentially damaging the DUT.
