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. The polarity of the red lead connection will be indicated along with

the voltage value.

NOTE:

 When only the figure “OL” is displayed, it indicates over range situation and the higher range has

to be selected.

 When the value scale to be measured is unknown beforehand, set the range selector at the highest

position.
