Measuring Voltage
1. Connect the black test lead to the "COM" jack and the
red test lead to the "
V Hz" jack.
2. Set the range switch to the desired
V
or
mV
range.
If the magnitude of the voltage to be measured is not
known beforehand, select the highest range and then
reduce it range by range until satisfactory resolution is
obtained.
3. Press "
Select
" button to select dc or ac measurement.
4. Connect the test leads across the load to be measured.
5. Read LCD display. For dc voltage measurement, the
polarity of red lead connection will be indicated as well.
6. In the ac measurement mode, you can press the "
"
button to make the display show "Hz" and then measure
the frequency. It means that you don't have to set the
range switch to the "
Hz/Duty
" range position for
frequency measurement. Press the "
" button twice
to restore the meter to ac voltage function.
Note:
For frequency measurement, the display will
show a zero value or other indefinite values if the
voltage of the input signal is less than about
300mV rms. It is normal.
