Safety Information
General Safety Summary
Carefully read the following safety precautions to avoid any personal injury or
damage to the instrument and any products connected to it. To avoid potential
hazards, please use the instrument as specified.
Use Proper Power Line
Only the power cord designed for the instrument and authorized by local country could be
used.
Ground the Instrument
The instrument is grounded through the protective earth conductor of the power line. To
avoid electric shock, please make sure the instrument is grounded correctly before
connecting its input or output terminals.
Connect the Signal Wire Correctly
The potential of the signal wire is equal to the earth, so do not connect the signal wire to a
high voltage.
Look Over All Terminals‟ Ratings
To avoid fire or electric shock, please look over all ratings and sign instruction of the
instrument. Before connecting the instrument, please read the manual carefully to gain
more information about the ratings.
Use Proper Overvoltage Protection
Make sure that no overvoltage (such as that caused by a thunderstorm) can reach the
product, or else the operator might expose to danger of electrical shock.
Electrostatic Prevention
Operate in an electrostatic discharge protective area environment to avoid damages
induced by static discharge. Always ground both the internal and external conductors of
the cable to release static before connecting.
Keep Well Ventilation
Inadequate ventilation may cause increasing of temperature, which will eventually
damage the instrument. So keep well ventilation and inspect the intake and fan regularly.
Avoid Circuit or Components Exposed
Do not touch exposed contacts or components when the power is on.

SIGLENT
User Manual III
Use proper Fuse
Use only the specified fuse.
Do Not Operate Without Covers
Do not operate the instrument with covers or panels removed.
Do Not Operate With Suspected Failures.
If you suspect damage occurs to the instrument, have it inspected by qualified service
personnel before further operations. Any maintenance, adjustment or replacement
especially to circuits or accessories must be performed by SIGLENT authorized
personnel.
Do Not Operate in Wet Conditions.
In order to avoid short circuiting to the interior of the device or electric shock, please do
not operate in a humid environment.
Do Not Operate in an Explosive Atmosphere.
In order to avoid damages to the device or personal injuries, it is important to operate the
device away from an explosive atmosphere.
Keep Product Surfaces Clean and Dry.
To avoid the influence of dust and/or moisture in air, please keep the surface of device
clean and dry.
Handling Safety
Please handle with care during transportation to avoid damages to buttons, knob
interfaces and other parts on the panels.

Measurement Category
Measurement Categories
The oscilloscopes can make measurements in measurement category I.
WARNING
This oscilloscope can only be used for measurements within its specified
measurement categories.
Measurement Category Definitions
Measurement category I is for measurements performed on circuits not directly connected
to MAINS. Examples are measurements on circuits not derived from MAINS, and
specially protected (internal) MAINS derived circuits. In the latter case, transient stresses
are variable; for that reason, the transient withstand capability of the equipment is made
known to the user.
Measurement category II is for measurements performed on circuits directly connected to
the low voltage installation. Examples are measurements on household appliances,
portable tools and similar equipment.
Measurement category III is for measurements performed in the building installation.
Examples are measurements on distribution boards, circuit-breakers, wiring, including
cables, bus-bars, junction boxes, switches, socket-outlets in the fixed installation, and
equipment for industrial use and some other equipment, for example. Stationary motors
with permanent connection to the fixed installation.
Measurement category IV is for measurements performed at the source of the low-voltage
installation. Examples are electricity meters and measurements on primary over current
protection devices and ripple control units.

Non-operation:-20℃to +70℃
Humidity
Under +35℃:≤90% relative humidity
+35℃to +40℃: ≤60% relative humidity
WARNING
To avoid short circuit inside the instrument or electric shock, please do not

Installation (overvoltage) Category
This product is powered by mains conforming to installation (overvoltage) category II.
WARNING
Make sure that no overvoltage (such as that caused by thunderbolt) can reach
the product, or else the operator might expose to danger of electric shock.
Installation (overvoltage) Category Definitions
Installation (overvoltage) category I refers to signal level which is applicable to equipment
measurement terminals connected to the source circuit. In these terminals, precautions
are done to limit the transient voltage to the corresponding low level.
Installation (overvoltage) category II refers to the local power distribution level which is
applicable to equipment connected to the AC line (AC power).

User Manual VII
Ventilation Requirement
This oscilloscope uses fan to force cooling. Please make sure that the air intake and
exhaust areas are free from obstructions and have free air. When using the oscilloscope
in a bench-top or rack setting, provide at least 10 cm clearance beside, above and behind
the instrument for adequate ventilation.
WARNING
Inadequate ventilation may cause temperature increase which would damage
the instrument. So please keep the instrument well ventilated during operation
and inspect the intake and fan regularly.

General Inspection
1. Inspect the shipping container for damage.
Keep the damaged shipping container or cushioning material until the contents of the
shipment have been checked for completeness and the instrument has passed both
electrical and mechanical tests.
The consigner or carrier shall be liable for the damage to instrument resulting from
shipment. SIGLENT would not be responsible for free maintenance/rework or
replacement of the unit.
2. Inspect the instrument.
In case of any damage, or defect, or failure, notify your SIGLENT sales
representative.
3. Check the Accessories
Please check the accessories according to the packing lists. If the accessories are
incomplete or damaged, please contact your SIGLENT sales representative.
