l
To obtain a stable reading when measuring input scope
30V rms frequency signal:
Set the rotary switch to
V
.
Then press
Hz%
to select Hz measurement mode
to
obtain frequency value.
When input scope 30V rms, please follow the above
step 2. carrying out the measurement.
l
When making frequency measurement at voltage or current
range, please mind the following signal requirement table:
4A 45Hz~1kHz
l
To obtain a stable reading when measuring input scope
30V rms frequency signal:
Set the rotary switch to
V
.
Then press
Hz%
to select % measurement mode
to
obtain
duty cycle value.
When input scope 30V rms, please follow the above
step 2. carrying out the measurement.
H. Measuring Duty Cycle (See figure 9)
The duty cycle measurement range is: 0.1%~99.9%. To
measure duty cycle, do the following:
1. Set up the Meter to measure frequency.
2. To select duty cycle, press
Hz %
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
The LCD displays 000.0% indicating the input signal is high
or low level.
l
When duty cycle measurement has been completed,
disconnect the connection between the testing leads and the
circuit under test, and remove the testing leads away from the
input terminals of the Meter.
