5-2-2 Hz/DUTY Measurements
Maximum rating input value 60.00kHz / 99%
CAUTION
The setting and measurement (At the time of AC voltage input) of the
Hz/DUTY are possible at the DCV function too. However, we recommend
the use in the ACV function.
1) Applications: Measures frequency and duty of any circuit.
2) Measurement procedure
①
Set the function switch
at ACV function. Push the
Hz/DUTY switch one time,
and select the Hz function.
(The unit display is Hz display.)
In the case of duty measurement,
then push the Hz/DUTY switch
one more time, and select
the duty function.
(The unit display is % display.)
②
Apply the red and black test pins to the circuit to measure.
③
Read the value on the display.
④
After measurement, remove the red and black test pins from
the circuit measured.
●
With measuring terminals disconnected, display may overflow
or value may unsteadily fluctuate. There are not malfunctions.
●
Input sensitivity varies according to frequency and wave-form.
●
Please refer to 8-2 Measurement Range and Accuracy.
●
It is only auto range mode.
●
When it returns it to the voltage function after the Hz/DUTY
measurement the range is fixed automatically. (DCV function is
400mV. ACV function is 4V.) Please stop measurement once to
cancel the manual range. And please do measurement after
the function is set up again.
●
DATA HOLD function does not work when measuring frequency.
●
The meter cannot measure frequency that does not go to and fro
O voltage.
