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 use the instrument only specified by this manual.
Use Proper Power Cord.
Only the power cord designed for the instrument and authorized for use within the 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 the power cord to the Protective Earth terminal before
connecting any inputs or outputs.
Connect the Probe Correctly.
If a probe is used, do not connect the ground lead to high voltage since it has isobaric electric potential as
the 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 the instrument.
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 be exposed to the danger of electrical shock.
Do Not Operate Without Covers.
Do not operate the instrument with covers or panels removed.
Do Not Insert Anything Into the Holes of Fan.
Do not insert anything into the holes of the fan to avoid damaging the instrument.
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 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 instrument temperature which would cause damage to the
instrument. So please keep the instrument 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 the
instrument in a humid environment.
