4. Taking Measurements
4.8 Duty Cycle Measurement
The duty cycle gives the relation of the duty (on) time (impulse time) to
the period duration on a square wave signal.
With this function you can measure the duty cycle of many different
circuitry designs.
Procedure
1. Connect the red probe to the V;
; ;
Ω
; CAP input (11) and the
black one to the COM input (12).
2. Set the rotary function switch (10) to “Hz%,
, V”. The unit is now
set to the voltage measuring mode. Twice press “Hz%“ (2) to reach
the duty cycle measuring mode. This is confirmed by “%” being
displayed.
3. Connect the probes to the circuitry to be measured and read the
duty cycle from the display.
