(4) If the problem still persists, contact RIGOL.
4. An exception occurs to the input in CR mode.
(1) Check whether the output of the DUT is normal, e.g. check whether an
oscillation occurs to the DUT.
(2) Check whether the range for the resistance is properly set.
(3) If the problem still persists, contact RIGOL.
5. An exception occurs to the input in CP 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 output of the DUT is normal, e.g. check whether an
oscillation occurs to the power supply; whether the rated power of the
power supply fails to reach the set power of the load.
(3) If the problem still persists, contact RIGOL.
6. An exception occurs to the transient feature test 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) Make a real-time measurement for the CC slew rate. If the value failed to
reach the standard, shorten the leads between the DUT and the instrument
as much as possible, because the long leads will result in a slow slew rate.
(3) Check whether the range of the load current is properly set.
(4) If the problem still persists, contact RIGOL.
7. The USB storage device cannot be recognized.
(1) Check whether the USB storage device can work normally.
(2) Make sure the USB storage device used is FAT32-format Flash storage type,
as this instrument does not support hardware storage type USB storage
device.
(3) Restart the instrument and insert the USB storage device to check it.
(4) If the USB storage device still cannot work normally, please contact
RIGOL.
