Notations Used In This Manual; Safety Precautions - Kikusui TOS9301PD User Manual

Support for touch current, protective conductor
current, and patient leakage current tests
(TOS9303LC only)
Various leakage current tests for medical instruments are sup-
ported in addition to those for general electric appliances.
Partial discharge measurement function
(TOS9301PD only)
Partial discharge, which could not be detected in with-
standing voltage tests up to now, can be measured. This
provides a step forward in insulation analysis, and
device and material evaluation.
LAN, USB, and RS232C
The product is standard equipped with LXI compatible
LAN, USB 2.0, USB-TMC compatible USB, and
RS232C interface.
Color liquid crystal display
Intuitive display and controls are provided through the 7-
inch display that shows various test settings, descrip-
tions, and drawings.

Notations Used in This Manual

• In this manual, the TOS9300, TOS9301, TOS9301PD,
TOS9302, TOS9303, and TOS9303LC electrical safety
analyzer are also referred to as the TOS93 series.
• The term "PC" is used to refer generally to both personal
computers and workstations.
• The term "EUT" is used to refer generally to an equip-
ment under test.
• Test names may be abbreviated as follows:
AC withstanding voltage: ACW, DC withstanding volt-
age: DCW, insulation resistance: IR, earth continuity:
EC, partial discharge: PD, leakage current: LC, touch
current: TC, protective conductor current: PCC, patient
leakage current: Patient.

Safety Precautions

When using this product, be sure to observe the precau-
tions in the Safety Information manual. Items specific to
this product are given below.
• This product generates high voltage. Improper oper-
ation can lead to serious accidents.
To prevent accidents, be sure to read "Safety Precau-
tions for Testing" (p.19) in this manual. Keep this manual
close to the product so that the operators can read the
manual at any time.
• You will receive a potentially fatal electric shock if:
• You touch an output terminal while output is being
generated.
• You touch a test lead that is connected to an output
terminal while output is being generated.
• You touch the EUT while output is being generated.
• You touch a location that is electrically connected to
an output terminal while output is being generated.
• You touch a location that is electrically connected to
an output terminal immediately after output is turned
off after a DC withstanding voltage test or insulation
resistance test has been performed.
• You may receive a potentially fatal electric shock if:
• You operate the tester without grounding it.
• You operate the tester without using rubber gloves for
electrical work.
• You come close to a location that is electrically con-
nected to an output terminal while output is being
generated.
• You come close a location that is electrically con-
nected to an output terminal immediately after output
is turned off after a DC withstanding voltage test or
insulation resistance test has been performed.
• In tests that use test leads, do not touch the tip of
test leads.
Risk of electric shock.
