MEASURING DUTY CYCLE
1. Connect the black test lead to the (-) jack COM and red lead to
the (+) jack (Hz).
2. Set the function switch to "Hz/% duty”.
3. Push the “Hz/%” button changing the function to % duty cycle.
4. Connect the test leads to the circuit to be measured. The range
will change that will display the measured duty cycle with the best
resolution.
