1-2 TOS9213S/ TOS9213AS
1.1 Outline
The TOS9213S/ TOS9213AS (hereinafter referred to as “the tester”) is withstanding
voltage/insulation resistance tester. The tester can perform DC withstanding voltage
testing and insulation resistance testing. The tester can operate at up to 10 kVDC (at
a maximum output of 50 W for up to 1 minute) in DC withstanding voltage testing.
The tester is capable of performing withstanding voltage testing on electronic equip-
ment and components in accordance with safety standards, including IEC, EN,
VDE, BS, UL, CSA, JIS, and the Electrical Appliance and Material Safety Law (in
Japan.)
The high-voltage block features a high-efficiency switching power supply and a
PWM-based switching amplifier. This ensures high and stable output extremely
resistant to power-supply and load fluctuations.
Because the tester boasts measurement accuracy that enables it to handle high-reso-
lution current measurements and judgements of values as small as tens of µA, it is
ideal for testing solar panels (photovoltaic panels) and other devices.
For insulation resistance testing, TOS9213S is compatible with the test voltage
range of 25 Vto 1000 V(at a resolution of 1 V) and the resistance measuring range
of 0.01 MΩto 9.99 GΩ(at rated current range of 50 nA to 1 mA maximum),
whereas TOS9213AS is compatible with the test voltage range of 25 Vto 1500 V
(at a resolution of 1V) and the resistance measuring range of 0.01 MΩto 9.99 GΩ
(at rated current range of 50nA to 1 mA maximum, or at rated current range of 50
nA to 0.1 mA if the test voltage setting exceeds 1020 V).
Not only can the tester make judgements using insulation resistance values, it can
also make judgments using measurements of the leakage current that flows through
the insulation resistance.
Once connected to a DUT, the tester can not only perform DC withstanding voltage
tests, and insulation resistance tests separately, but can also conduct these tests con-
secutively using the program function. When combined with the high-voltage scan-
ner TOS9221/TOS9220, each tester can operate using four channels. The tester can
be connected to four scanners, thus permitting the connection of a total of 16 chan-
nels. Further, when used together with the earth continuity tester TOS6200, the tes-
ter can also be applied to safety tests such as earth continuity tests. (When combined
with the scanner, the output voltage is up to 6 kV.)
The tester is equipped with GPIB and RS-232C as standard features, making them
highly applicable to a variety of automatic testing systems that require greater safety
and reliability.

1.2 Features
■Two testing functions – DC withstanding voltage, and
insulation resistance tests
When connected to a DUT, the tester can perform these two different tests consecutively.
■DC withstanding voltage test at 10 kV
(maximum output of 50 W)
The tester can perform DC withstanding voltage tests for a wide voltage range of up
to 10 kV(maximum output of 50 W and maximum duration of 1 minute). The tester
is equipped with a stable, low-ripple DC/DC converter with a voltage regulation of 1
% or less.
■Improved measurement accuracy
The tester is equipped with a digital voltmeter for withstanding voltage testing with
an accuracy of ±(1 % of the reading +20 V), and another for insulation resistance
testing with an accuracy of ±(1 % of the reading +1 V). The two voltmeters display
measured values not only during a test but also during execution of a program.
The tester is equipped with an ammeter for withstanding voltage testing that features
accuracy of ±(3 % of the reading +5 μA*1). Thus, it is capable of performing high-res-
olution tests, such as those that are required for PVpanels. The two ammeters display
measured values not only during a test but also during execution of a program.

■Insulation resistance test at 25 V to 1500 V (resolution of 1 V) /
0.01 MΩto 9.99 GΩ(at rated current range of 50 nA to 1 mA
maximum *2)
TOS9213S allows you to conduct an insulation resistance test at test voltage
range of 25 Vto 1000 V(resolution of 1 V) with resistance measuring range of
0.01 MΩto 9.99 GΩ. Whereas, TOS9213AS allows you to conduct a test at
test voltage range of 25 Vto 1500 V(resolution of 1 V) with resistance mea-
suring range of 0.01 MΩto 9.99 GΩ.
*2: For TOS9213AS, if the test voltage setting exceeds 1020 V, the resistance
measuring range is valid at rated current range of 50 nA to 0.1 mA.

■Leakage current judgement (insulation resistance testing)
For insulation resistance testing, in addition to the conventional judgement method
using resistance values, the tester can also perform judgements using the value of
the leakage current that flows through the insulation resistance.
■Fully programmable GPIB and RS-232C interfaces as a
standard feature
All functions except for the POWER switch, KEYLOCK, and program execute
(AUTO) functions, are remote-controllable. Test conditions such as the test voltage,
judgement value, and test time can be controlled remotely in DC withstanding volt-
age and insulation resistance tests. Measured values and measurement results can
also be read back by remote control. The GPIB and RS-232C interfaces provided as
a standard feature smoothly interface the tester with a PC, sequencer, and other
devices.
■Flexible control function realized by a high-voltage scanner
When combined with the optional high-voltage scanner TOS9220 (5 kVAC/6
kVDC), the tester can test multiple points in withstanding voltage and insulation
resistance tests. Using the tester panel, each channel can be set to a HI/LO/OPEN
voltage. One scanner can operate up to four channels. Up to four scanners can be
connected to the tester, enabling the simultaneous operation of a total of 16 chan-
nels. The TOS9221 is equipped with a function for detecting connections between
the high-voltage test leadwire and the DUT, thus ensuring highly reliable testing.

■Rise-time control function
In DC withstanding voltage testing, and insulation resistance testing, a voltage can
be slowly increased until it reaches a required test value, instead of applying the
required test voltage to the DUT immediately after the start of a test. The voltage
rise time can be set to 0.1 s through 99.9 s at a resolution of 0.1 s, and to 100 s
through 200 s at a resolution of 1 s. The start voltage, which is applied at the start of
a test, can be set to 0 % to 99 % of the test voltage at a resolution of 1 %. Thus, the
tester conforms to the requirement for the type certification test under the UL stan-
dard and the withstanding voltage test under the IEC standard that less than half of
the test voltage be applied initially and slowly increased for a specified period of
time before the test voltage is reached.
■Discharge function
Generally, DUTs contain capacitive elements. Therefore, DUTs remain charged
immediately after a DC withstanding voltage test or insulation resistance test has
been conducted, resulting in the danger of electric shock. The tester has a function
for forcibly discharging the DUT upon completion of DC withstanding voltage test
or insulation resistance test. You can set the discharge time to a value between 0 and
300 s.
■Enhanced safety
To enhance safety, the tester is equipped with a number of devices and safety func-
tions, including safe output terminals, a discharge function, and an analog voltmeter
that constantly monitor the output-terminal voltages. Such safety measures also
include a danger lamp that constantly monitors output-terminal voltages even when
no test is under way and lights up when a voltage is detected, in addition to an inter-
lock function that cuts off output in coordination with an external device.
■Voltage hold function
During judgement, this function allows the tester to retain measured voltages
recorded upon completion of a test, while it is still outputting the judgement results.
Combined with the rise-time control function, the voltage hold function enables
detection of the dielectric breakdown voltage.
■Output voltage monitoring function
When the output voltage deviates from ± (10 % of the setting +50 V), the monitor-
ing function activates to suspend the test, ensuring highly reliable testing.
■High operability
The tester is easy to operate, allowing the operator to start using it without difficulty.
The tester displays the primary test conditions on the first page of the menu, with
the secondary test conditions shown on the following pages. To set test conditions,
simply use the cursor key to choose from among the items displayed on the LCD,
and then turn the rotary knob. The function keys allow you to jump to items to be
set. During a test, the output voltage can be changed using the rotary knob.
