J. MEASURING DUTY CYLE (SEE FIGURE 11)
(figure 11)
Warning!
To avoid harm to yourselves, never attempt to input an effective voltage over 60V in DC or
30V in AC.
To measure duty cycle, connect the Meter as follows:
1. Insert the red test lead into the
Hz
terminal and the black test lead into the COM terminal.
2. Set the rotary switch to Duty%.
3. Connect the test leads across with the object being measured.
4. The measured value shows on the display, the unit is %.
Note
- This measurement method is applicable to input scope <30Vrms. When the input scope
≥30Vrms, the input protection circuit may move which cause cannot get any reading.
- When duty cycle testing has been completed, disconnect the connection between the
temperature probe and the circuit under test.
