Troubleshooting
The commonly encountered failures and their solutions are listed below. When you encounter those
problems, please solve them following the corresponding steps. If the problem remains still, please contact
SIGLENT
and provide your device information.
1. If the screen is still dark with nothing displayed after pressing the power key.
1) Check whether the power cord is well connected.
2) Check if the power switch on the front panel is pressed firmly.
3) Check whether the power fuse is burned out. If the fuse needs to be changed, please use the
specified fuse.
4) Restart the instrument after finishing the above inspections.
5) If the instrument still can’t start up properly, please contact
SIGLENT
.
2. The reading doesn’t change when a current signal is input.
1) Check whether the test lead is correctly inserted into the HI and LO terminals of current
measurement.
2) Check whether the DCI or ACI measurement function is enabled.
3) Check whether the DCI measurement function is used to measure AC current.
3. The reading is abnormal when a voltage signal is input.
1) Check whether the test lead is correctly inserted into the HI and LO terminals of voltage
measurement.
2) Check whether the DCV or ACV measurement function is enabled.
3) Check whether the DCV measurement function is used to measure AC voltage.
4. The USB storage device cannot be identified.
1) Check whether the USB storage device is in good condition.
2) Make sure the USB storage device you used is a flash storage device. This instrument does not
support hardware storage type.
3) Restart the instrument and then insert the USB storage device.
4) If the problem persists, please contact
SIGLENT
.
