5
).
2. Press the input/output selection key (
8
) to display "INPUT" (
13
).
3. Press the V mV selection key (
6
) to select V DC or mV DC (
20
) according
to the desired measurement range.
4. Connect the red test lead to the V terminal (
4
) and the black lead to the
COM terminal (
3
).
5. Connect the other end of the red test lead to the positive pole of the
voltage to be measured and the black lead to the negative pole (earth).
6. The result is displayed on (
16
).
* The numbers in parenthesis refer to the Description of the front panel (Page
21) and the Description of the display screen (Page 22).
