G. Measuring Frequency / Duty Cycle
To avoid harms to you, please do not attempt to input
voltage higher than 30V rms.
To measure frequency and duty cycle, connect the
Meter as Figure 3-7 and do the following:
1.
2.
3.
Insert the red test lead into the Hz terminal and the
black test lead into the COM terminal.
Set the rotary switch to
7730) and press BLUE button to select the Hz
measurement mode for frequency measurement or
% for duty cycle measurement.
The BLUE button cycles among
and duty cycle.
Connect the test leads across with the object being
measured.
The measured value shows on the primary display.
