Measurement Category

Measurement Category

DS4000 series digital oscilloscopes can make measurements in Measurement

Category I.

WARNING

This oscilloscope can only be used for measurements within its specified measurement categories.

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.

Measurement category II is for measurements performed on circuits directly connected to the low voltage installation. Examples are measurements on household appliances, portable tools and similar equipment.

Measurement category III is for measurements performed in the building installation.

Examples are measurements on distribution boards, circuit-breakers, wiring, including cables, bus-bars, junction boxes, switches, socket-outlets in the fixed installation, and equipment for industrial use and some other equipment, for example. Stationary motors with permanent connection to the fixed installation.

Measurement category IV is for measurements performed at the source of the low-voltage installation. Examples are electricity meters and measurements on primary overcurrent protection devices and ripple control units.

DS4000 Quick Guide V

RIGOL

Ventilation Requirement

This oscilloscope uses fan to force cooling. Please make sure that the air intake and exhaust areas are free from obstructions and have free air. When using the oscilloscope in a rack, provide at least 10 cm clearance beside, above and behind the instrument for adequate ventilation.

WARNING

Inadequate ventilation may cause temperature increase which would damage the instrument. So please keep the instrument well ventilated during operation and inspect the intake and fan regularly.

To Use the Security Lock

If needed, you can use the security lock (please buy it yourself) to lock the oscilloscope to a fixed location. The method is as follows, align the lock with the lock hole and plug it into the lock hole vertically, turn the key clockwise to lock the oscilloscope and then pull the key out.

To Use the Built-in Help System

The help system of this oscilloscope provides instructions for all the function keys

(including menu keys) at the front panel. Press Help to open the help interface and press again to close the interface. The help interface mainly consists of two parts.

The left is “Help Options” and you can use “Button” or “Index” mode for selection.

The right is “Help Display Area”.

Button:

Default mode. In this mode, you can press the button (except the power key , the knob and menu page up/down key / ) at the front panel directly to get the corresponding help information of that button in the “Help Display Area”.

Use to select “To Index” and then press down the knob to switch to Index mode.

Index:

In this mode, use to select the item that needs to get help (for example: “Band

Width”). The item currently selected is displayed with brown shading. Press down

Troubleshooting

The commonly encountered failures and their solutions are listed below. When you encounter those problems, please solve them following the corresponding steps. If the problem remains still, please contact RIGOL and provide your device information (acquisition method: Utility  System  System Info).

1. The screen is still dark (no display) after power on:

(1) Check if the power is correctly connected.

(2) Check if the power switch is really on.

(3) Check if the fuse is burned out. If the fuse needs to be changed, please return the instrument to the factory and RIGOL authorized personnel will change the fuse for you.

(4) Restart the instrument after finishing the above inspections.

(5) If it still does not work correctly, please contact RIGOL.

2. The signal is sampled but no waveform of the signal is displayed:

(1) Check if the probe is correctly connected to the signal connecting wire.

(2) Check if the signal connecting wire is correctly connected to the BNC

(namely channel connector).

(3) Check if the probe is correctly connected to the item under test.

(4) Check if there are signals generated from the item under test (you can connect the probe compensation output signal to the problematic channel to determine which has problems, the channel or the item under test).

(5) Resample the signal.

3. The tested voltage amplitude is ten times higher or lower than the actual value:

Check whether the attenuation coefficient of the channel complies with the attenuation ratio of the probe.

4. There is waveform display but not stable:

(1) Check the trigger signal source: check whether the Source in the trigger menu complies with the signal channel actually used.

(2) Check the trigger type: general signals should use “Edge” trigger and video signal should use “Video” trigger. Only when the proper trigger type is used,

DS4000 Quick Guide 29

RIGOL

can the waveform be displayed stably.

(3) Try to change the Coupling to “HF Reject” or “LF Reject” to filter out the high-frequency or low-frequency noise that disturbs the trigger.

(4) Change the trigger holdoff setting.

5. No display after pressing RUN/STOP:

Check if the MODE at the trigger panel (TRIGGER) is “Normal” or “Single” and if the trigger level exceeds the waveform range. If yes, set the trigger level to the middle or set the MODE to “Auto”.

Note that using the AUTO button could automatically finish the above setting.

6. The display of waveform is ladder-like:

(1) The horizontal time base might be too low. Increase the horizontal time base to increase the horizontal resolution and improve the display.

(2) If Type is “Vectors”, the lines between the sample points may cause ladder-like display. Set Type to “Dots” to solve the problem.

7. The USB storage device can not be recognized:

(1) Check whether the USB storage device can work normally.

(2) Make sure that the USB storage device used is flash storage type. This oscilloscope does not support hardware storage type.

(3) Make sure if the capacity of the USB storage device is too large. It is recommended that the capacity of the USB storage device being used with this oscilloscope is no larger than 4 GBytes.

(4) Restart the instrument and then insert the USB storage device.

(5) If the USB storage device still can not be used normally, please contact

RIGOL.
