symbol will appear on the LCD screen. No manual measurement range and analog bar will be displayed in Capacity mode.
Caution:
a) When measuring the capacity, all the powers within the tested circuits must be disconnected and the capacitance shall be
sufficiently discharged
b)When measuring big capacitors, it takes a longer time, about 100uF per 15 seconds.
c) When the measurement is completed, immediately disconnect the meter and the measured circuit.

XV. Frequency (Hz)
1. Press "
" button to conduct frequency measurement.
Respectively plug in the meter pen into "VΩHz"and"COM".
2. Have the testing end of the meter pen connected in parallel with the signal sources to be measured and read the results
from the display. (Note: No analog bar will displayed in this mode)
3. When testing frequency, press "Hz/DUTY" once to conduct duty cycle measurement. Press "Hz/DUTY" once more to
enter the frequency status.
4. Read the current results from the display.
Caution:
a) Do not input signals higher than 60V, otherwise it may
damage the instrument and pose dangers to human safety.
b) After all the measurements are completed, it is necessary
to disconnect the meter pen and the tested circuit.
