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 connected to it. To prevent potential hazards, please 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 essential to connect the earth 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 and markers on the instrument 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 the operator might expose to danger of electrical 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 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.

DP800A Quick Guide III
Do Not Operate in Wet Conditions.
In order to avoid short circuiting to the interior 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
operate the device away from an explosive 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 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.
Handling Safety.
Please handle with care during transportation to avoid damages to buttons, knob
interfaces and other parts on the panels.

DP821A: (3)
DP811A:
(1) Used to output the voltage and current of the channel.
(2) This terminal is connected to the instrument chassis and ground wire (power
cord ground terminal) and is in grounded state.
(3) Used to sense the actual voltage at the load to compensate the voltage drop
caused by the leads between the power supply and the load.

Connection methods of the output terminal:
Method 1:
Connect the test lead to A of the output terminal.
Method 2:
Rotate the outer nut of the output terminal counterclockwise and connect the
test lead to B of the output terminal; then, rotate the outer nut of the output
terminal clockwise. This connection method can eliminate the error caused by
the resistance of the output terminal.
Note: Connect the positive terminal of the test lead with the (+) terminal of the
channel output and connect the negative terminal of the test lead with the (-)
terminal of the channel output.
