Safety Requirement

General Safety Summary

Please review the following safety precautions carefully before putting the instrument into operation so as to avoid any personal injuries or damages to the instrument and any product connecte d to it. To preve nt potential haza rds, please us e the instrument only specified by this manual.
Use Proper Power Cord.
Only the power cord designed for the instrument and authorized for use within the local country could be used.
Ground The Instrument.
The instrument is grounded through the Protective Earth lead of the power cord. To avoid electric shock, it is e ssential t o connect the ea rth terminal of power cord to the Protective Earth terminal before any inputs or outputs.
Connect the Probe Correctly.
If a probe is used, do not connect the ground lead to high voltage since it has the isobaric electric potential as ground.
Observe All Terminal Ratings.
To avoid fire or shock hazard, observe all ratin gs and ma rkers on the ins trument and check your manual for more inf o rmatio n abo ut ratings before connecting.
Use Proper Overvoltage Protection.
Make sure that no overvoltage (such as that caused by a thunderstorm) can reach the product, or else the operator might expose to danger of electrical shock.
Do Not Operate Without C o ve r s.
Do not operate the instrument with covers or panels removed.
Do Not Insert Anything into the Holes of Fan.
Do not insert anything into the holes of the fan to avoid damaging the instrument.

Use Proper Fuse.
Please use the specified fuse.
Avoid Circuit or Wire Exposure.
Do not touch exposed junctions and components when the unit is powered.
Do Not Operate With Suspected Failures.
If you suspect damage occurs to the instrument, have it inspected by qualified service personnel before further operations. Any maintenance, adjustment or replacement especially to circuits or accessories must be performed by RIGOL authorized personnel.
Keep Well Ventilation.
Inadequate ventilation may cause increasing of temperature or damages to the device. So please keep well ventilated and inspect the intake and fan regularly.
Do Not Operate in Wet Conditions.
In order to av oid short circuiting t o the interi or of the device or electric shock, please do not operate in a humid environment.
Do Not Operate in an Explosive Atmosphere.
In order to avoid damages to the device or personal injuries, it is important to operat e the dev ice away fro m an explosive at m osphere.
Keep Product Surfaces Clean and Dry.
To avoid the influence of dust and/or moisture in air, please keep the surface of device clean and dry.
Electrostatic Prevention.
Operate in an electrostatic discharge protective area environment to avoid damages induced by static discharges. Always ground both the internal and external conductors of the cable to release static before connecting.
Proper Use of Battery.
If a battery is supplied, it must not be exposed to high temperature or in contact with fire. Keep it out of the reach of children. Improper change of battery (note: lithium battery) may cause explosion. Use RIGOL specified battery onl y.

Troubleshooting

This chapter lists the commonly en count ered failures of DG4000 an d their solutions. When you encounter thos e proble ms, please sol ve t hem f ollowing the correspondin g steps. If the problem persists, please contact RIGOL and provide your device information (Utility System Sys 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) Restart the instrument after finishing the above inspections. (4) If it does not work co rrectly, contact RIGOL fo r ou r service.
2. The settings are correct but no waveform is generated
(1) Check if the BNC cable is correctly connected to the channel output
terminal ([Output1] or [Output2]). (2) Check if the BNC cable can work correctly. (3) Check the Output1 or Output2 button, if it is turned on. (4) Set PowerOn as “Last” and then restart the instrument after finishing the
above inspections. (5) If it does not work correctly, contact RIGOL for our service.
3. The USB storage device cannot be recognized:
(1) Check if the USB storage device can work normally. (2) Make sure the USB storage device is USB flash storage device. The
generator doesn’t support hard drive-based USB storage device. (3) Restart th e instr u m ent, reinsert the USB storage device and check it. (4) If the USB storage device still can not be recognized, please contact
RIGOL.
