WARNING
Do not disassemble the instrument by yourself. Otherwise, you might be
exposed to the danger of electric shock. Any maintenance, adjustment or
replacement especially to circuits or accessories must be performed by
RIGOL authorized personnel.
WARNING
Only the exclusive power cord designed for the instrument and authorized
for use within the local country could be used. For replacement of the
power cord, please contact RIGOL .
This chapter lists the potential problems or failure, as well as the solutions in using
the instrument. If the following problems occur, locate and resolve the problems
according to the following steps. If the problems still persist, contact RIGOL and
provide your instrument information to us. (For instrument information, press
Utility

System.)
1. The instrument cannot be powered on.
(1) Check whether the power cord is correctly connected.
(2) Check whether you have pressed down the Power key on the front panel.
(3) Plug out the power cord, and check whether the voltage selector is in the
proper position, whether the fuse conforms to the fuse rating, and whether
the fuse is intact. For fuse replacement, refer to "Fuse Replacement".
(4) If the problem still persists, contact RIGOL .
2. An exception occurs when the load sinks the current in CC mode.
(1) Check whether the cable that connects the instrument to the DUT is
reversely connected, which causes the instrument to report the alarm for
reverse connection.
(2) Check whether the input power calculated based on the input voltage and
the current that the load sinks exceeds the power limit of the instrument,
thus resulting in overpower protection.
(3) Check whether the range of the load current is properly set.
(4) If the problem still persists, contact
RIGOL
.
3. An exception occurs to the input in CV mode.
(1) Check whether the cable that connects the instrument to the DUT is
reversely connected, which causes the instrument to report the alarm for
reverse connection.
(2) Check whether the maximum output voltage of the DUT is smaller than the
set load voltage.
(3) Check whether the DUT works normally.
