2. Rotate the switch on
V
position. The “AC” symbol is shown at display
3. Pressing the

key to select the correct range or using the Autorange feature
(see paragraph 4.2.3). If the voltage value under test is unknown, select the highest
range
4. Insert the red test lead plug into
V
Ω
jack and the black test lead plug into
COM
jack (see Fig. 3)
5. Connect the two long ends of test leads to the desired circuit (see Fig. 3) then reading
will be displayed
