1. For voltage frequency measurement, the input voltage should
be within the required range (see the technical specification for
frequency measurement). For current frequency measurement, the
measured current must be greater than
2A
.
2. For duty cycle measurement, the input voltage should be between
4Vp-p and 10V-p, and the frequency of the signal should be between
4Hz and 1kHz.
3. When measuring the voltage frequency, connect the black test
probe to the
"COM"
jack and the red test probe to the " " jack
When measuring the current frequency, connect the black test probe
to the
"COM"
jack and the red test probe to the
"10A"
jack
4. When the meter enters the frequency or duty cycle measurement
function, press the yellow button to return to the voltage or current
measurement function, and the meter will cancel the auto range
Note
press the
"Hz%"
button once and the screen will display the frequency value
of the input signal. Note: When the function switch is in the " " position, the
meter has no frequency and duty cycle measurement function.
2. If you want to measure the duty cycle, press the
"Hz%"
button again and
the screen will display the duty cycle of the input signal.
Measuring capacitance
1. Connect the black test probe to the
"
COM
"
jack and the red test probe to
the
" "
jack (or
" "
jack).
2. Set the function switch to position. If the reading on the screen is not
zero, the reading should be subtracted from the subsequent measurement
reading and the result is the true value of the measured capacitance.
3. Short the two pins of the capacitor to be measured to fully discharge the
residual voltage, and then connect the two test probes to both pins of the
capacitor.
