7. Troubleshooting
1. The screen is still black and there is no display after you press the power switch,
please follow the steps below:
Check whether the power is connected correctly.
Check whether the fuse below the power connector meets the specified type
and rating and in good condition (the cover can be pried open with a
flat-blade screwdriver).
Restart the instrument after completing the above inspections.
If the problem still exists, please contact MULTICOMP PRO for our service.
2. The measured value of the output signal amplitude does not match the
displayed value:
Check whether the actual load value of the signal is consistent with the load
value set in the instrument. Please refer to Load on page 52.
If you encounter other problems, please try to reset the settings (see Restore to the
factory setting on page 59) or restart the instrument. If it still can not work properly,
please contact MULTICOMP PRO for our service.
