Do not Operate with Suspected Failures.

If suspected damage or malfunctions occur with the instrument, have it inspected by qualified service personnel before further operations.

Provide Proper Ventilation.

Refer to the manual’s installation instructions for proper ventilation of the instrument.

Use only UL/cUL or cCSAus certified probes with the oscilloscope.

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 VS5000 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 HI and LO 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 VS5000 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 VS5000 series oscilloscope, please inspect the instrument as following steps:

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 option of RIGOL without

waiting for claim settlement.

To Perform a Functional Check

Perform this quick functional check to verify that the instrument is operating correctly.

1. Prepare for using the instrument.

Use the power cords designed for the oscilloscope only. Connect to a power source that delivers 100 to 240 VAC, 45Hz to 440Hz. Power up the system, initiate the program. Click the Storage button, select Load Default in the menu box.

VS5000 Series are equipped with dual channels plus external trigger, and 16 channels logic analyzer (only for VS5***D models).

Please defer to the following steps to connect to signal:

1） Set the attenuation switch on the probe to 10X (Figure 1-6) and connect the

probe to CH1 on the oscilloscope. Align the slot in the probe connector with the key on the CH1 BNC connector. Push to connect, and twist to the right to lock the probe in place. Attach the probe tip and ground lead to the Probe compensator 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 the Probe menu, select attenuation to 1:10. Set the switch to X10 on the probe and connect it to CH 1 of the oscilloscope. When using the probe hook-tip, insert the tip onto the probe firmly to ensure a proper connection. Attach the probe tip to the Probe Compensator and the reference lead to the ground connector, select CH 1, and then press the

To Use Digital Leads (for VS5***D only)

1. Switch off power supply of the Device under Test if necessary to avoid short circuit. Since no voltage is applied to the leads at this step, the oscilloscope may remain on.

2. Connect one end of the flex cable FC1868 to the Logic Analyzer Input; connect

the other end to Logic Head LH1116. It is unnecessary to switch off power supply of the oscilloscope while connecting the cable.
