Measurement Operation (11)
G. Frequency & Duty Cycle Measurement (see figure 12)
Frequency Measurement
The measurement ranges are: 1kHz, 10kHz, 100kHz
and 1MHz. The maximum measurement range is 1MHz.
To measure frequency, connect the Meter as follows:
1. Insert the red test lead into the
V Hz terminal
and the black test lead into the COM terminal.
2. Set the rotary switch to any voltage or current
measurement positions.
3. Press Hz to display the frequency of present signal.
4. 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 which has
the highest sensitivity.
l The attenuate amplitude of signal is different from
different measuring positions and ranges, therefore
the required input amplitude is different when
measuring frequency at different measuring positions
and ranges.
l When Hz measurement has been completed,
disconnect the connection between the testing leads
and the circuit under test.
