• Check whether the power switch at the front panel is on.
• Remove the power cord and check whether the voltage selector is on
the correct scale, whether the specification of the fuse is correct and
whether the fuse is intact. If the fuse needs to be changed, please refer
to “

”.
• If the problem remains, please contact

2. The constant voltage output is abnormal.
• Check whether the maximum output power of the scale currently
selected fulfills the load requirement. If yes, go to the next step.
• Check the cable connecting the load and power supply for short-
circuits.
• Check whether the load is normal.
• Check whether the current setting value of this scale is proper. If it is
too low, increase it.
