Safety Notices
Review the following safety precautions carefully before operating the instrument to
avoid any personal injuries or damages to the instrument and any products
connected to it.
To avoid potential hazards use the instrument as specified by this user’s guide only.
The instrument should be serviced by qualified personnel only.
To Avoid Fire or Personal Injury.
Use Proper Power Cord. Use the power cord designed for the instrument and
authorized in your country only.
Connect and Disconnect Accessories. Do not connect or disconnect probes or
test leads while they are connected to a voltage source
Ground The Instrument. The oscilloscope is grounded through the grounding
conductor of the power cord. To avoid electric shock the instrument grounding
conductor(s) must be grounded properly, before making connections to the input or
output terminals of the instrument.
Connect The Probe. The probes’ ground terminals are at the same voltage level of
the instrument ground. Do not connect the ground terminals to a high voltage.
Observe All Terminal Ratings. To avoid fire or shock hazard, observe all ratings
and marks on the instrument. Follow the user’s guide for further ratings information
before making connections to the instrument.
Do Not Operate Without Covers. Do not operate the instrument with covers or
panels removed.

Use Proper Fuse. Use the fuse of the type, voltage and current ratings as specified
for the instrument.
Avoid Circuit or Wire Exposure. Do not touch exposed connections and
components when power is on.
Do Not Operate With Suspected Failures. If suspected damage occurs with the
instrument, have it inspected by qualified service personnel before further
operations.
Provide Proper Ventilation. Refer to the installation instructions for proper
ventilation of the instrument.
Do not Operate in Wet/Damp Conditions.
Do not Operate in an Explosive Atmosphere.
Keep Product Surfaces Clean and Dry.
The disturbance test of all the models meet the limit values of A in the
standard of EN 61326: 1997+A1+A2+A3, but can’t meet the limit values
of B.
Measurement Category
The DS1000CA series Digital Oscilloscope is intended to be used for measurements in
Measurement Category I.
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.

User’s Guide for DS1000CA Series
WARNING
IEC Measurement Category I. The input terminals may be connected to circuit
terminal in IEC Category I installations for voltages up to 300 VAC. To avoid the
danger of electric shock, do not connect the inputs to circuit’s voltages above 300
VAC.
Transient overvoltage is also present on circuits that are isolated from mains. The
DS1000CA series Digital Oscilloscopes is designed to safely withstand occasional
transient overvoltage up to 500 Vpk. Do not use this equipment to measure circuits
where transient overvoltage could exceed this level.

To Inspect the Instrument
After receiving a new DS1000CA series oscilloscope, please inspect the instrument as
follows:
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
been checked mechanically and electrically.
2. Check the accessories.
Accessories supplied with the instrument are listed in "Accessories" in this guide.
If the contents are incomplete or damaged notify the RIGOL Sales
Representative.
3. Inspect the instrument.
In case there is any mechanical damage or defect, or the instrument does not
operate properly or fails performance tests, notify the RIGOL Sales
Representative.
If the shipping container is damaged, or the cushioning materials show signs of
stress, notify the carrier as well as the RIGOL sales office. Keep the shipping
materials for the carrier’s inspection.
RIGOL offices will arrange for repair or replacement at RIGOL’s option without
waiting for claim settlement.

To Perform a Functional Check
Perform this quick functional check to verify that the instrument is operating
correctly.
1. Turn on the instrument.
¾Use the power cord designed for the oscilloscope only.
¾Use a power source that delivers 100 to 240 VACRMS, 45Hz to 440Hz.
¾Turn on the instruments, and wait until the display shows the waveform window.
¾Push the Storage button, select Storage in the top menu box and push the
Factory menu box.
Figure 1-4
Turn on the instrument
WARNNING:
To avoid electric shock, be sure the oscilloscope is properly grounded.
2．Input a signal to a channel of the oscilloscope
①Set the attenuation switch on the probe to 10X and connect the probe to Channel
1 on the oscilloscope.
To do this:
¾Align the slot in the probe connector with the key on the CH 1 BNC connector.
¾Push to connect, and twist to the right to lock the probe in place.
¾Attach the probe tip and ground lead to the PROBE COMP connector.

To Compensate Probes
Perform this adjustment to match the characteristics of the probe and the channel
input. This should be performed whenever attaching a probe to any input channel
the first time.
1. From CH1 menu, set the Probe attenuation to 10X (press CH1→Probe→10X).
Set the switch to 10X on the probe and connect it to CH1 of the oscilloscope.
When using the probe hook-tip, inserting the tip onto the probe firmly to ensure
a proper connection.
Attach the probe tip to the Probe compensator connector and the reference lead
to the ground pin, Select CH1, and then press AUTO.
2. Check the shape of the displayed waveform.

3. If necessary, use a non-metallic tool to adjust the trimmer capacitor of the probe
for the flattest square wave being displayed on the oscilloscope.
4. Repeat if necessary.
WARNNING: To avoid electric shock while using the probe, be sure the
perfection of the insulated cable, and do not touch the metallic portions of
the probe head while it is connected with a voltage source.

To Display a Signal Automatically
The oscilloscope has an automated feature to display the input signal best-fit. The
input signal should be 50Hz or higher and a duty cycle is greater than 1%.
Press the AUTO button, the oscilloscope automatically sets up VERTICAL,
HORIZONTAL and TRIGGER controls to display the input signal. Adjust the controls
manually to get the best results if necessary.
Connect a signal to the Channel 1 (CH1).
1. Connect a signal to the oscilloscope as described above.
2. Press AUTO.
The oscilloscope may change the current settings to display the signal; adjusts the
vertical and horizontal scaling, the trigger coupling, type, position, slope, level, and
mode.
