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.

User’s Guide for DS1000CA Series

RIGOL

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

III

RIGOL

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 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.
