INTRODUCTION
This brief guide includes important safety and installation information for your WaveJet
Series oscilloscope, along with brief operating procedures to get you started capturing,
viewing, and analyzing your waveforms.
WJ-GS-E Rev B 5
WaveJet Series
SAFETY REQUIREMENTS
This section contains information and warnings that must be observed to keep the
instrument operating in a correct and safe condition. You are required to follow
generally accepted safety procedures in addition to the safety precautions specified in
this section.
Safety Symbols and Terms
Where the following symbols or terms appear on the instrument’s front or rear panels,
or in this manual, they alert you to important safety considerations.
This symbol is used where caution is required. Refer to the
accompanying information or documents in order to protect against
personal injury or damage to the instrument.
This symbol warns of a potential risk of shock hazard.
This symbol is used to denote the measurement ground connection.
This symbol is used to denote a safety ground connection.
This symbol shows that the switch is a On/Standby switch. When it is
pressed, the scope’s state toggles between Operating and Standby
state. This switch is not a disconnect device. To completely remove
power to the scope, the power cord must be unplugged from the AC
outlet after the scope is placed in Standby state.
This symbol is used to denote "Alternating Current."
The CAUTION sign indicates a potential hazard. It calls attention to a
CAUTION
WARNING
procedure, practice or condition which, if not followed, could possibly
cause damage to equipment. If a CAUTION is indicated, do not
proceed until its conditions are fully understood and met.
The WARNING sign indicates a potential hazard. It calls attention to
a procedure, practice or condition which, if not followed, could
possibly cause bodily injury or death. If a WARNING is indicated, do
not proceed until its conditions are fully understood and met.

CAT I
standard and is applicable for the oscilloscope front panel measuring
terminals. CAT I rated terminals must only be connected to source
circuits in which measures are taken to limit transient voltages to an
appropriately low level.
Operating Environment
The instrument is intended for indoor use
and should be operated in a clean, dry
environment.
Note: Direct sunlight, radiators, and other
heat sources should be taken into account
when assessing the ambient temperature.
The design of the instrument has been
verified to conform to EN 61010-1 safety
standard per the following limits:
Installation (Overvoltage) Categories II
(Mains Supply Connector) & I (Measuring
Terminals)
Pollution Degree 2
Protection Class I
Note:
Installation (Overvoltage) Category II refers
to local distribution level, which is applicable
to equipment connected to the mains supply
(AC power source).
Installation (Overvoltage) Category I refers
to signal level, which is applicable to
equipment measuring terminals that are
connected to source circuits in which
measures are taken to limit transient
voltages to an appropriately low level.
Pollution Degree 2 refers to an operating
environment where normally only dry nonconductive pollution occurs. Occasionally a
Getting Started Manual
WARNING
The scope must not be operated in
explosive, dusty, or wet/damp
atmospheres.
CAUTION
Protect the scope’s display touch
screen from excessive impacts with
foreign objects.
CAUTION
Do not exceed the maximum specified
front panel terminal (CH1, CH2, CH3,
CH4, EXT) voltage levels. Refer to
Specifications for more details.
CAUTION
Do not connect or disconnect probes or
test leads while they are connected to a
voltage source.

WaveJet Series
temporary conductivity caused by
condensation must be expected.
Protection Class 1 refers to a grounded
equipment, in which protection against
electric shock is achieved by Basic
Insulation and by means of a connection to
the protective ground conductor in the
building wiring.
Cooling Requirements
The instrument relies on forced air cooling
with internal fans and ventilation openings.
Care must be taken to avoid restricting the
airflow around the apertures (fan holes) at
each side of the scope. To ensure adequate
ventilation it is required to leave a10 cm (4
inch) minimum gap around the sides of the
instrument.
AC Power Source
The instrument operates from a singlephase, 100 to 240 V
source at 50/60 Hz (+/-5%), or single-phase
100 to 120 V
rms
400 Hz (+/-5%).
No manual voltage selection is required
because the instrument automatically adapts
to line voltage.
Depending on the accessories installed (PC
port plug-ins, Ethernet & GPIB options, etc.),
the instrument can draw up to 75 W (75 VA).

CAUTION
Do not block the ventilation holes

Do not allow any foreign matter to enter
the scope through the ventilation holes,

Getting Started Manual
Power and Ground Connections
The instrument is provided with a grounded
cord set containing a molded three-terminal
polarized plug and a standard IEC320 (Type
C13) connector for making line voltage and
safety ground connection. The AC inlet
ground terminal is connected directly to the
frame of the instrument. For adequate
protection against electrical shock hazard,
the power cord plug must be inserted into a
mating AC outlet containing a safety ground
contact. Use only the power cord specified
for this instrument and certified for the
country of use.
The scope should be positioned to allow
easy access to the socket-outlet. To
completely remove power to the scope,
unplug the instrument’s power cord from the
AC outlet.
It is recommended that the power cord be
unplugged from the AC outlet if the scope is
not to be used for an extended period of
time.
Calibration
The recommended calibration interval is one year. Calibration should be performed by
qualified personnel only.
Cleaning
Clean only the exterior of the instrument,
using a damp, soft cloth. Do not use
chemicals or abrasive elements. Under no
circumstances allow moisture to penetrate
the instrument. To avoid electrical shock,
unplug the power cord from the AC outlet
before cleaning.
WARNING
Electrical Shock Hazard!
Any interruption of the protective
conductor inside or outside of the
scope, or disconnection of the safety
ground terminal creates a hazardous
situation.
Intentional interruption is prohibited.
CAUTION
The outer shells of the front panel
terminals (CH1, CH2, CH3, CH4, EXT)
are connected to the instrument’s
chassis and therefore to the safety
ground.
WARNING
Electrical Shock Hazard!
No operator serviceable parts inside.
Do not remove covers.
Refer servicing to qualified personnel.
WJ-GS-E Rev B 9
WaveJet Series
Abnormal Conditions
Operate the instrument only as intended by
the manufacturer.
If you suspect the scope’s protection has
been impaired, disconnect the power cord
and secure the instrument against any
unintended operation.
The scope’s protection is likely to be
impaired if, for example, the instrument
shows visible damage or has been subjected
to severe transport stresses.
Proper use of the instrument depends on
careful reading of all instructions and labels.
Any use of the scope in a manner not
specified by the manufacturer may
impair the instrument’s safety
protection. The instrument and related
accessories should not be directly
connected to human subjects or used
for patient monitoring.
