1)
Clip the red alligator clip to the battery positive pole; clip the black alligator clip to
the battery negative pole.
2) Once the device is powered on, it will enter DC voltage test mode as default.
Short press the mode button to enter the menu, short press the down button to
place the cursor in the AC voltage mode, and short press the mode button to
enter the AC voltage waveform display mode.
3) The auxiliary ground wire is connected to one end of the circuit under test, and
the probe contacts the other end of the test circuit. The LCD display will read the
maximum and minimum voltage value (Figure 4), and display the signal waveform
in real time. You can adjust the sampling frequency by pressing the Up/Down
Button.
4) In Figure 4, “time: 10 ms” is the time interval indicated by each large grid. This
time reading will change with the sampling frequency.
5) Long press and hold the mode button until the device switches to digital display
mode. The device will display the true RMS value, the minimum voltage value,
and the maximum voltage value.
