1Safety Requirement
1.1 General Safety Summary
Please review the following safety precautions carefully before putting the instrument
into operation so as to avoid any personal injury or damage to the instrument and
any product connected to it. To prevent potential hazards, please follow the
instructions specified in this manual to use the instrument properly.
• Use Proper Power Cord.
Only the exclusive power cord designed for the instrument and authorized for
use within the destination country could be used.
• Ground the Instrument.
The instrument is grounded through the Protective Earth lead of the power cord.
To avoid electric shock, it is essential to connect the earth terminal of the power
cord to the Protective Earth terminal before connecting any inputs or outputs.
• Connect the Probe Correctly.
If a probe is used, the probe ground lead must be connected to earth ground.
Do not connect the ground lead to high voltage. Improper way of connection
could result in dangerous voltages being present on the connectors, controls or
other surfaces of the oscilloscope and probes, which will cause potential hazards
for operators.
• Observe All Terminal Ratings.
To avoid fire or shock hazard, observe all ratings and markers on the instrument
and check your manual for more information about ratings before connecting
the instrument.
• Use Proper Overvoltage Protection.
Ensure that no overvoltage (such as that caused by a bolt of lightning) can reach
the product. Otherwise, the operator might be exposed to the danger of an
electric shock.
• Do Not Operate Without Covers.
Do not operate the instrument with covers or panels removed.
• Do Not Insert Objects Into the Air Outlet.
Do not insert objects into the air outlet, as doing so may cause damage to the
instrument.
• Use the Proper Fuse.
Please use the specified fuses.

• Avoid circuit or wire exposure.
Do not touch exposed junctions and components when the instrument is
powered on.
• Do Not Operate With Suspected Failures.
If you suspect damage occurs to the instrument, have it inspected by RIGOL
authorized personnel before further operations. Any maintenance, adjustment or
replacement especially to circuits or accessories must be performed by RIGOL
authorized personnel.
• Keep Well Ventilation.
Inadequate ventilation may cause an increase of temperature in the instrument,
which would cause damage to the instrument. So please keep the instrument
well ventilated and inspect the air outlet and the fan regularly.
• Do Not Operate in Wet Conditions.
To avoid short circuit inside the instrument or electric shock, never operate the
instrument in a humid environment.
• Do Not Operate in an Explosive Atmosphere.
To avoid personal injuries or damage to the instrument, never operate the
instrument in an explosive atmosphere.
• Keep Instrument Surfaces Clean and Dry.
To avoid dust or moisture from affecting the performance of the instrument,
keep the surfaces of the instrument clean and dry.
• Prevent Electrostatic Impact.
Operate the instrument in an electrostatic discharge protective environment to
avoid damage induced by static discharges. Always ground both the internal and
external conductors of cables to release static before making connections.
• Use the Battery Properly.
Do not expose the battery (if available) to high temperature or fire. Keep it out of
the reach of children. Improper change of a battery (lithium battery) may cause
an explosion. Use the RIGOL specified battery only.
• Handle with Caution.
Please handle with care during transportation to avoid damage to keys, knobs,
interfaces, and other parts on the panels.
WARNING
Equipment meeting Class A requirements may not offer adequate protection to broadcast
services within residential environment.

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. Thus, you must know the transient withstand
capability of the equipment.
• Measurement category II is for measurements performed on circuits directly
connected to 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 and socket-outlets) in
the fixed installation, and equipment for industrial use and some other
equipment. For example, stationary motors with permanent connection to a
fixed installation.
• Measurement category IV is for measurements performed at the source of a
low-voltage installation. Examples are electricity meters and measurements on
primary overcurrent protection devices and ripple control units.
1.4 Ventilation Requirement
This instrument uses a fan to force cooling. Please make sure that the air inlet and
outlet areas are free from obstructions and have free air. When using the instrument
in a bench-top or rack setting, provide at least 10 cm clearance beside, above and
behind the instrument for adequate ventilation.
CAUTION
Inadequate ventilation may cause an increase of temperature in the instrument, which
would cause damage to the instrument. So please keep the instrument well ventilated and
inspect the air outlet and the fan regularly.
