Chapter 4 Common troubleshooting
The most commonly encountered failures and their solutions are listed
below. Please use these steps listed if an error occurs. If the problem
persists, please contact SIGLENT .
1. The instrument will not power on.
(1) Check whether the power is correctly connected.
(2) Check whether the power switch at the front panel is on.
(3) Remove the power cord and check whether the voltage selector is at
the proper setting, whether the specification of the fuse is correct and
whether the fuse is intact. If the fuse needs to be changed, refer to “To
Replace the Fuse”.
(4) If the problem remains, please contact SIGLENT.
2. The constant voltage output is abnormal.
(1) Check whether the maximum output power of the scale currently
selected fulfills the load requirement. If yes, go to the next step.
(2) Check whether the cable connecting the load and power supply is
short-circuited and is making good contact.
(3) Check whether the load is normal.
(4) Check whether the current setting value of this scale is proper; if it is
too low, increase it accordingly
(5) If the problem remains, please contact SIGLENT.
