DANGER lamp
• The DANGER lamp illuminates while the test is in progress.
If the DANGER lamp is illuminated, the voltage applied to
AC LINE IN (EUT) is output to the AC LINE OUT terminal.
Measurement category
• Measurement terminals A and B comply with IEC Standard
Measurement Category II.
Measurement Category II (CAT II) is used to measure the
primary circuit of equipment (household electric appliances,
portable tools, etc.) that is connected directly to a low-volt-
age installation such as an outlet.
Ground terminal
• In case of measuring the touch current in the condition of
“Earth line disconnected status” of the EUT, a hazardous
voltage may apply to the ground terminal. Do not touch the
ground terminal while the test is in progress.

General Description
This chapter gives an overview and describes the features.

18 TOS3200
Product Overview
The TOS3200 Leakage Current Tester is used to measure the leakage current of the four
tests*1 that are required to secure the safety of electric equipment. The tester covers general
electric and electronic equipment excluding medical equipment. Various measurement net-
works and wide-bandwidth measurement circuits are built in allowing the execution of tests
meeting the requirements of safety standards such as IEC, EN, UL, VDE, and JIS as well as
Electrical Appliance and Material Safety Law. Because the TOS3200 is equipped with an out-
let and terminal block for supplying power, connecting the power line of the EUT is easy.
Features
●Measurement of TC and PCC conforming to IEC 60990*2
The TOS3200 is capable of measuring the TC using a measurement network (perception,
reaction, let-go, and electric burn based on IEC 60990). In addition, the PCC can be mea-
sured simply by connecting the EUT to the TOS3200.
The internal voltmeter can measure the DC, true rms, and peak values and supports a mea-
surement frequency up to 1 MHz for AC measurement, satisfying the recommended items of
the standard.
●Equipped with eight measurement networks as standard (circuit networks repre-
senting the human body impedance)
The TOS3200 is equipped with eight measurement networks as standard including that of
IEC 60990 allowing the measurement of the TC on most general electric and electronic
equipment.*3
●Fault simulation of the power line supplied to the EUT
The TOS3200 supplies power not only to the EUT, but also allows you to carry out fault simu-
lation easily as required by the standard such as protective grounding disconnection, power
line disconnection, and polarity inversion.
●Program test that allows tests to be executed in sequence
Tests containing up to 100 steps can be executed consecutively by arbitrarily combining the
TC and PCC measurements.
●Meter Measurement Mode with a voltmeter having the TC measurement and SELV
detection functions
The TOS3200 is equipped with a meter measurement mode that separates the power line
control and specializes in the measurement functions. It can be used in a similar manner as
conventional analog leakage ammeter.
In Meter Measurement Mode, the voltage between measurement terminals can be measured
in addition to the TC measurement. The TOS3200 is also equipped with a SELV detection
function that warns using a DANGER lamp if the preset SELV voltage is exceeded. For
example, this feature is convenient if you want to check whether the voltage is exceeding the
safety extra low voltage (SELV); measure the TC to check whether the circuit is a limited cur-
rent circuit; and use these results to judge whether the circuit is a hazardous live.
●CONV function that converts the measured value to a current at the desired supply
voltage
Judgment can be performed by converting the measured power line voltage and the TC or
PCC to the TC or PCC of a preset power line voltage.

General Description
CAL ALARM function that warns the expiration of the calibration period
A warning message will be generated when a preset calibration period passes. It is also pos-
sible to limit the use of the TOS3200 by activating the protection status when the period
elapses.
Function for holding the maximum value during the measurement
The maximum TC or PCC during the measurement can be held. The maximum value can be
measured even if the current fluctuates during the measurement.
Function for setting a wait time until the test is actually executed after starting the
power supply
You can set a wait time for the test (time until the test is actually executed after starting the
power supply to the EUT). This feature is useful if you want to measure the current after the
EUT reaches the steady state avoiding the transient state of the EUT immediately after turn-
ing the power on.
Window comparator function that sets the upper and lower limits of judgement
You can set not only the upper reference of the TC or PCC but also the lower reference. This
feature helps to discover breaks in test leads and mistakes in the setup/procedure and allows
highly reliable tests.
Stores up to 100 test conditions
The test conditions of up to 100 individual tests (TC or PCC measurement) can be saved with
a name.*5 Up to 100 sequence programs for program tests can also be saved with a name.*4
The number of the safety standard on which the test is based and the EUT model can be
used as a name for the test conditions.
Stores the data for up to 50 test results
The test result, the date/time of the test, and the test conditions can be stored. Up to 50
results can be stored separately for individual tests and program tests.
Equipped with RS-232C, USB, and GPIB as standard
The TOS3200 is equipped with RS-232C, USB, and GPIB as standard. You can control test
conditions and read the measured values and test results through a PC or a sequencer.
*1 Withstanding Voltage Test, Insulation Resistance Test, Earth Continuity Test, and Leakage
Current Test
*2 IEC 60990: Methods of measuring TC and PCC
The current that is referred to as the “leakage current” is divided into TC (current that flows
when a human being touches the electric equipment) and PCC (current that flows through the
protective conductor of a Class I equipment).
*3 Medical equipment is not supported.
*4 Among the 100 presets, test conditions of TC conforming to the safety standards are stored
to presets 00 to 50 in advance. These presets can be recalled and used in the TC test.
*5 Up to 100 steps in a program and up to 500 steps total in all programs.

Options
The following options are available for the TOS3200.
For details on the options, contact your Kikusui agent or distributor.
Rack Mounting Option
This option allows the terminal block for the EUT on the rear panel to be used from the front
panel making it easy to connect the EUT even after the TOS3200 is rack mounted.
Test Probe
p. 49 A test probe can be used in place of the test lead in the TC measurement. It provides fingertip
control to start the test.
