, enter the AC voltage measurement. Auto range by press key,
and Manual range by press .
Manual range： 0.000V  6.6V range
00.00V

66V range
000.0V

660V range
000.0mV  660mV range
c. Connect test leads across the source or load under measurement.
d. You can get reading from LCD.
NOTE:

When only the figure “OL” is displayed, it indicates over range situation and the higher range has
