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.

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.

!WARNNING:
To avoid electric shock, be sure the oscilloscope is properly grounded.
2 Input a signal to a channel of the oscilloscope
Set 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.

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.

The 
knob moves the signal vertically, and it is calibrated. Note that turning the 
knob, a voltage value is displayed for a short time indicating its value with respect to the ground reference located at the center of the screen. Also notice that the ground symbol on the left side of the display moves in conjunction with the
knob.
Measurement hints
If the channel is DC coupled, measuring the DC component of the signal by simply noting its distance from the ground symbol.
If the channel is AC coupled, the DC component of the signal is blocked, allow you to use greater sensitivity to display the AC component of the signal.
