The separately sold accessories shown here can all be used with the withstanding voltage testers and insulation resistance testers
shown in this catalog with the exception of the limiting conditions for each item. Since some of these accessories may not be able
to be used with previous types not described in this catalog, please ask your dealer or the manufacturer when conditions are
unclear.
■Remote Control Box
This enables test on and reset operations to be performed by
remote control.
(mainly for withstanding voltage testers)
These are handy probes for use with withstanding voltage
testers. These probes employ a design in which all test
switches on the probe can be pressed when holding onto the
probe by its grip.
Test leads with alligator clips are to
be used exclusively for earth
continuity testing.

■Low-Voltage Test Probe (for TOS6100/6200)
This test probe is to be used exclusively for earth continuity
testing. Test on and reset can be performed using the switch
on the probe.

☛Please contact your dealer or the manufacturer in cases when
electrically insulated gloves, electrically insulated rubber
sheets and so forth are required.
■Warning Light Unit
This warning light unit is used
to indicate the status of
withstanding voltage testers (test
or judgement). This unit can be
turned on and off by a 100 V AC
input or a make contact signal.
●PL01-TOS
* This can not be used with TOS6200,
TOS9200/9201, TOS7200
■Buzzer Unit
This buzzer unit is used when the volume obtained with the
electronic buzzer incorporated
in withstanding voltage testers
is not sufficient. This unit can
be turned on and off by a 100 V
AC input or make contact
signal.
■Model TOS1200 Withstanding Voltage Tester Current
Calibrator: For calibration of current sensitivity of
withstanding voltage testers
❏Calibration of Leakage Current Detection Sensitivity
As a result of containing an internal test load resistor, the
TOS1200 enables switching of ammeter sensitivity and load
resistance values automatically for easy calibration of the
sensitivity of leakage current detection.
❏Direct Reading of Error from Error Display Scale
The main scale consists of an error display scale ranging
from -10% to +10% around a central full scale value. Thus,
if the leakage current detection sensitivity of the withstanding
voltage tester is a value of 1, 2 and 5 steps or 1, 2, 4 and 8
steps, the error can be read directly from the scale. The
auxiliary scale consists of a ratio display scale in which the
full scale value is taken to be 1.1, thereby enabling
accommodation of values outside the range of the main scale.
❏Ammeter Ranges
The ranges of the ammeter consist of 0.5, 1, 2, 5, 10, 20, 50
and 100 mA, and values equal to 0.8 times those values can
be set. This is convenient for withstanding voltage testers
of the type in which leakage current detection sensitivity is
set digitally (1, 2, 4 and 8 steps).
❏Eliminates Need for Power Supply
The TOS1200 offers outstanding portability since it does
not require a power supply.
❏AC/DC Selection Switch
