Measuring Duty Cycle

Duty cycle (or duty factor) is the percentage of time a signal is

above or below a trigger level during one cycle (Figure 16).

To measure duty cycle, proceed as follows:

1. Turn on the meter, then set up the meter as shown in Figure 15.

2. Insert the black test lead into the COM terminal and the red test

lead into the terminal.

3. Set the Function Rotary Switch to the Hz position. Then press

Hz/DUTY once to select DUTY Cycle measurement (then, a “%”

symbol is indicated on the display).

4. Connect the test leads to the circuit under test. The measured

value is shown on the display.
