Issue Description
AC Under Voltage alarm generate, what should be done?
Solution
Possible Causes:
1) The AC undervoltage alarm threshold is not set properly on the SMU.
2) The power grid is faulty.

Measures:

1) Check whether the AC undervoltage alarm threshold is properly set. If no, adjust it to a proper value.

2) Check whether the AC input voltage is below the AC undervoltage alarm threshold (180V AC by default). If yes, handle the AC input fault.
