General Safety Summary
Please review the following safety precautions carefully before putting the
instrument into operation so as to avoid any personal injury or damage 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 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 essential to connect the earth 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 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.
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 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.
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.
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 only.
Handling Safety.
Please handle with care during transportation to avoid damages to buttons, knob
interfaces and other parts on the panels.
Do Not Provide Power for the Active Load.
In order to avoid the anti-irrigation current which leads to the power control loop out
of control and damage to the powered device, this power supply can only provide
power for the pure load without the current output function.

Test Preparations
You need to finish the following preparations before performing the performance
verification test.
1. Perform self-test to make sure that the instrument can work normally.
Connect the instrument to AC power supply using the power cord provided with
the accessories. Press the power switch key at the front panel; the instrument
starts and performs self-test. You can press Utility Test/Cal after power-on
to examine the self-test information (including the top board, bottom board, fan
and temperature). If the self-test fails, please turn off and then turn on the
instrument to perform the self-test again and examine the self-test information.
If the self-test still fails, please contact RIGOL. Make sure that the reason that
results in the self-test failure are found and solved. Perform the performance
verification test only after the instrument passes the self-test.
Notes:
Before connecting the power, make sure that the setting of the voltage
selector at the rear panel of the power supply matches the AC power supply
to be connected and the fuse currently installed matches the input voltage.
The input voltages supported by DP800 series and the matching fuses are
as shown in the table below.

Before performing the self-test, make sure that there is no connection at
the front and rear panel terminals of the power supply.
2. Make sure that the power supply is within the calibration period (1 year). If
calibration is required, please contact RIGOL.
3. Run the instrument for at least 30 minutes.

4. Make sure that the environment temperature is between 20℃and 30℃and the
relative humidity is less than 80%.
5. The test connecting wires used should be as short as possible. For the channels
that support the Sense function, please short-circuit the (S+) and (+) terminals,
(S-) and (-) terminals (as shown in Figure 2-2 or Figure 3-2) of the channels
respectively and turn on the Sense function of the corresponding channel before
performing the test.
Note:
The tests introduced in this manual should be performed by professionals. During
the tests, there might be dangerous voltage at the output terminals of the power
supply as well as certain test devices.

Test Precautions
The output terminal of the power supply is as shown in Figure 1-1. The output
terminal is a metal conductor with certain contact resistance (
r
∆
) and when the
output current of the power supply is
I
, the voltage of this terminal is
IrV ×∆=
e
.
Therefore, during the test process, the voltage test point is always located at A to
reduce the error caused by the terminal voltage as far as possible. Besides, the
contact resistance between this terminal and the power output wire/the voltage
feedback wire inside the instrument chassis can also cause error (about 2mV, called
offset
U
).
When testing the load regulation rate, voltage peak-peak value and transient
response time, the test devices are connected to the output terminal via A and the
load resistor is connected to the output terminal via B.
Figure 1-1 Output Terminal
During the test, please pay attention to shield the effect of the environmental space
radiation noise on the test effectively.
Test Result Record
Record and keep the test results of each test item. The test result record forms,
which provide all the test items and the corresponding performance specification
limits as well as spaces for users to record the test results, of all models of DP800
series programmable linear DC power supply are provided in “Appendix A: Test
Result Record Forms” of this manual.

Preparations
When the power supply is in CV state, the main parameters to be tested include CV
load regulation rate, CV linear regulation rate, CV ripple and noise, transient
response time, CV programming and readback accuracy.
Before performing the tests, select the appropriate voltage via the “voltage selector”
at the rear panel of the power supply according to the AC line voltage of the country
(230V is taken as an example in all the tests in this manual). Under normal
temperature (about 25℃), make connections according to Figure 2-1 or Figure 2-2
using the devices recommended in “Recommended Test Devices”. During the
test process, please set the voltage of the AC power supply according to the voltage
selected of the “voltage selector” at the rear panel of the power supply.
