Measurement Operation (12)

Duty Cycle Measurement

The duty cycle measurement range is 0.01% ~ 99.99%.

To measure duty cycle:

1. Set up the Meter to measure frequency.

2. To select duty cycle, press Hz again (or until the %

symbol is shown on the display).

3. Connect the test leads across with the object being

measured.

The measured value shows on the display.

Note

l It is recommended to use mV

range.

l The polarity of trigger slope is positive.

l The attenuate amplitude of signal is different from

different measuring positions and ranges, therefore

the required input amplitude is different when

measuring duty cycle at different measuring positions

and ranges.

l When duty cycle measurement has been completed,

disconnect the connection between the testing leads

and the circuit under test.
