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 prevent potential hazards, plea se use
the instrument only specified by this manual.
Use Proper Power Cord.
Only the power cord designed for the instrument and authorized by 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.
Observe All Terminal Ratings.
To avoid fire or shock hazard, observe all ratings an d markers on the instrume nt and
check your manual for more information about 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 th e op erator might expose to danger of electrica l shock.
Do Not Operate Without Covers.
Do not operate the instrument with covers or panels removed.
Use Proper Fuse.
Please use the specified fuses.
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 oper at ions. 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.
II DP800A Quick Guide
RIGOL
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 device away from an explo sive atmosphere.
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 elect r ostatic discharge protective area enviro nment to avoid damages
induced by static discharges. Always ground both the internal and external
conductors of the cable to release static before connecting.
Handling Safety.
Please handle with care during transportation to avoid damages to buttons, knob
interfaces and other parts on the panels.

1. Input power requirement
DP800A series power supply can accept three kinds of AC power supplies:
50Hz–60Hz frequency; 100V, 115V and 230V voltages.
2. Check the voltage selector at the rear panel
Before connecting to power, make sure that the setting voltage of the voltage
selector at the rear panel matches the input voltage.
3. Check the fuse
When the instrument leaves factory, proper fuse is installed. Please check
whether the fuse matches the input voltage according to the “Input Power
Requirement” at the rear panel.
4. Connect the instrument power cord
Connect the instrument to AC power supply using the power cord provided in
the accessories.
To avoid electric shock, make sure that the instrument is correctly

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 (Utility Sys Info).
1. The instrument can not start up.
(1) Check whether the power is correctly connected.
(2) Check whether the power switch at the front panel is really on.
(3) Remove the power cord and check whether the voltage selector is at the
proper scale, whether the specification of the fuse is correct and whether
the fuse is intact. If the fuse needs to be changed, ref er to “To Replace the
Fuse”.
(4) If the problem remains, please contact RIGOL.
2. The constant voltage output is abnormal.
(1) Check whether the maximum output power of the scale currently selected
fulfills the load requirement. If yes, go to the next step.
(2) Check whether the cable connecting the load and power supply is
short-circuited and in good contact.
(3) Check whether the load is normal.
(4) Check whether the current setting value of this scale is proper; if it is too
low, increase it properly.
(5) If the problem remains, please contact RIGOL.
3. The constant current output is abnormal.
(1) Check whether the maximum output power of the scale currently selected
fulfills the load requirement. If yes, go to the next step.
(2) Check whether the cable connecting the load and power supply is
short-circuited and in good contact.
(3) Check whether the load is normal.
(4) Check whether the voltage setting value of this scale is proper; if it is too
low, increase it properly.
(5) If the problem remains, please contact RIGOL.
4. 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 dev ice being used is flash storage type.
This oscilloscope does not support hardware storage type.
(3) Restart the instrument and then insert the USB storage device to check it.
(4) If the USB storage device still can not be used normally, please contact
RIGOL.
