Safety Requirement
General Safety Summary
Please review the following safety precautions carefully before putting the instrument
into operation so as to avoid any personal injuries or damages to the instrument and
any product connected to it. To prevent potential hazards, please use the instrument
only specified by this manual.
Use Proper Power Cord.
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 lead of the power cord. To
avoid electric shock, it is essential to connect the earth terminal of power cord to the
Protective Earth terminal before any inputs or outputs.
Connect the Probe Correctly.
Do not connect the ground lead to high voltage since it has the isobaric electric
potential as ground.
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.
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.
Do Not Operate Without Covers.
Do not operate the instrument with covers or panels removed.
Use Proper Fuse.
Please use the specified fuses.
Avoid Circuit or Wire Exposure.
Do not touch exposed junctions and components when the unit is powered.
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 RIGOL authorized
personnel.

III
Keep Well Ventilation.
Inadequate ventilation may cause increasing of temperature or damages to the device.
So please keep well ventilated and inspect the intake and fan regularly.
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.
Electrostatic Prevention.
Operate in an electrostatic discharge protective area environment to avoid damages
induced by static discharges. Always ground both the internal and external conductors
of the cable to release static before connecting.
Handling Safety
Please handle with care during transportation to avoid damages to buttons, knob
interfaces and other parts on the panels.
