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.
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.

General Inspect
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
passed both electrical and mechanical test.
The consigner or carrier shall be liable for the damage to instrument resulting
from shipment, without free maintenance or replacement by RIGOL.
2. Inspect the instrument.
In case of any damage, or defect, or failure, notify your RIGOL Sales
Representative.

Panels and User Interface
The first thing to do with a new oscilloscope is to know its panels. This chapter helps
to be familiar with the layout of the knobs and keys and how to use them. Read the
chapter carefully before further operations.
The Front Panel
The front panel is divided into “function menu”, “run control”, “trigger control”,
“horizontal control”and “vertical control”areas.
Thereinto, five grey menu buttons which lie beside LCD screen (defined No.1 to No.5)
are used to switch current menu options. Other function buttons are used to enable
the access to many measurement features associated with advanced functions,
mathematics, reference or to run control features. In addition, multi-function knob is
available to adjust waveform brightness or switch menus, but others are applied to
adjust offset, volts/div or s/div.

Interfaces:
USB Host: It is used to connect DS1000CA with external USB devices when the
oscilloscope is regarded as “Host Device”. For example, connect a USB flash device.
Signal Input: Two channels are provided: CH1 and CH2.
EXT TRIG Input: It is applied to input external trigger signal.

Interfaces:
Pass/Fail: It is used to output the pass/fail test result.
RS232: To connect the oscilloscope with external devices by serial port.
USB Device: It is used to connect DS1000CA with external USB devices when the
oscilloscope is regarded as a “Slave Device”. For example, connect with PC for
remote control.
Notation definitions in this User’s Guide:
Throughout this manual, notation symbols of buttons and knobs are the same of
those on front-panel.
A box around the name of the key denotes MENU function buttons on
front-panel, such as Measure.
() denotes the multi-function knob .
denotes the two POSITION knobs.
denotes the two SCALE knobs.
denotes the LEVEL knob.
The name with a drop shadow denotes the menu operating key, such as
Waveforms soft key in Storage menu.
Use “→”to divide operation steps. Such as: Storage →Storage, indicates press
“Storage”button on the front panel, then press “Storage”menu.

Function Check
Perform this quick functional check to verify that the instrument is operating
correctly.
1. Turn on the instrument
Use the power cord designed for the oscilloscope to connect the instrument and
AC power which delivers 100 to 240 VACRMS, 45Hz to 440Hz. Press the power
switch to turn on the instruments, waiting until the display shows the waveform
window.
2. Recall factory setting
Press Storage →Storage →Factory →Load, to recall factory setting.

Turn on the instrument
WARNNING
To avoid electric shock, be sure the oscilloscope is properly grounded.
3. Input a signal to a channel of the oscilloscope
Push BNC plug of probe into CH1 BNC connector, then twist the BNC cable to
right to lock the probe in place. Switch on the probe to 10X.

Press CH1 →Probe →10X to set probe attenuation of the oscilloscope, so as
to make sure the measurement result is correct. (Default probe attenuation
scale is 1X.)
Attach the probe tip to the Probe compensator connector and the reference
lead to the ground pin. Press AUTO, within a few seconds, a square wave will
display (approximately 1 kHz 3 V peak- to- peak).
Push the OFF button or push the CH1 button again to turn off Channel 1.
Push the CH2 button to turn on channel 2, repeat steps above.
