Setup
Battery Charging
The device is equipped with a 2500mAh large-capacity battery. Before first use, or when the battery indicator shows low charge, connect the device to a power source using the provided Type-C charging cable.
- Connect the Type-C cable to the charging port on the side of the device.
- Connect the other end of the cable to a standard USB power adapter (not included) or a computer USB port.
- The battery indicator on the screen will show charging status.
Initial Power On
To power on the device, press and hold the DMM / Power button until the screen illuminates. The device will boot into its default mode, typically the multimeter function.
Operating Instructions
Oscilloscope Mode
The oscilloscope function allows for waveform visualization and analysis with a 10MHz bandwidth and 50MSa/s sampling rate. It supports various waveform measurements and features like zoom, multi-trigger, and cursor measurements.
- Press the FUNC button to switch to Oscilloscope mode.
- Connect the oscilloscope probe to the appropriate input jack.
- Adjust the vertical (V/div) and horizontal (Time/div) scales using the navigation buttons to properly display the waveform.
- Use the SELECT button to cycle through measurement parameters or trigger settings.
