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.

III
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.
Do Not Operate in an Explosive Atmosphere.
In order to avoid damage 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 the air, please keep the surface of the device clean
and dry.
Electrostatic Prevention.
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.
Proper Use of Battery.
If a battery is supplied, it must not be exposed to high temperature or in contact with fire. Keep it out
of the reach of children. Improper change of battery (note: lithium battery) may cause explosion. Use
RIGOL specified battery only.
Handling Safety.
Please handle with care during transportation to avoid damage to buttons, knob interfaces and other
parts on the panels.

Chapter 1 Overview
Test Preparations
The following preparations should be done before the test.
1. Self-test: perform self-test to make sure that the oscilloscope can work normally;
2. Warm-up: warm the oscilloscope up for at least 30 minutes;
3. Self-calibration: calibrate the oscilloscope.
Self-test
When the oscilloscope is in power-on state, press the power key at the lower left corner of the
front panel to start the oscilloscope. During the start-up, the instrument performs a series of self-test
items and users can hear the sound of relay switching. The welcome screen is displayed after the
self-test is finished. Users can view the self-test results by pressing UTIL System 
SelfTestInfo.
If the self-test fails, make sure that the problems are found and resolved and do not perform
calibration and performance tests until the instrument passes the self-test.
Self-calibration
Make sure that the oscilloscope has been warmed up or running for more than 30 minutes before
performing self-calibration. Then, follow the steps to calibrate the oscilloscope.
1. Connect the [Trig Out/Calibration] connector at the rear panel of the oscilloscope to the four
analog input channels and the external trigger input channel at the front panel respectively using
a one-to-five BNC (M) cable.
2. Press UTIL Self-Cal at the front panel to enter the self-calibration interface.
3. Press Start and the oscilloscope will start to execute the self-calibration.
4. It takes about 20 minutes (15 minutes for dual-channel models) to finish the calibration. Restart
the oscilloscope when “Calibration finished, please restart the oscilloscope!” is displayed.
5. Press ACQ Acquisition to select “Average”; then, press Averages and use to set the
number of averages to 16.
6. Disconnect the input signals of all the channels. Set the vertical scale of each channel to 2 mV/div
and view the offset of the waveform of each channel. If the offset is greater than 1 div, you should
perform self-calibration again.

Test Result Record
Record and keep the test result of each test. In the Appendix of this manual, a test result record form
which lists all the test items and their corresponding performance limits as well as spaces for users to
record the test results, is provided.
Tip:
It is recommended that users photocopy the test record form before each test and record the test
results in the copy so that the form can be used repeatedly.
Specifications
The specification of each test item is provided in chapter 2. For other specifications, refer to
DS6000
User’s Guide
or DS6000 Data Sheet (can be downloaded from www.rigol.com).
