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.

●
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 exam-
ple, 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.
