Setup
Initial Charging
Before first use, fully charge the device using the provided USB Type-C cable and power adapter. The charging port is located on the side of the unit.
Probe Connection
Connect the oscilloscope probes to the CH1 and CH2 BNC input connectors. For multimeter functions, connect the multimeter leads to the appropriate input ports (A, mA, COM, QVC+).
Power On/Off
Press and hold the Power key to turn the device on or off.
Operating Instructions
Switching Modes
Press the Mode key to toggle between Oscilloscope mode and Multimeter mode.
Oscilloscope Mode
In Oscilloscope mode, the device displays real-time waveforms. Key features include:
- Bandwidth: Up to 50 MHz.
- Sample Rate: 125 MSa/s (real-time).
- Channels: Dual channel operation.
- Waveform Refresh Rate: Up to 10,000 Wfms/s.
- Record Length: Up to 8K.
Basic Waveform Display
Connect the oscilloscope probe to the circuit under test. Press the Auto key for automatic waveform scaling and triggering. This function provides a quick and convenient way to display stable waveforms.

Figure 3: Example of waveform display in Oscilloscope mode.
Adjusting Settings
Use the navigation keys to adjust vertical (voltage) and horizontal (time) scales. The CH1/2 key switches between channels. The HDR key adjusts the horizontal range.
Triggering
Press the Trig/Δ key to access trigger settings. Adjust trigger level, mode, and source to stabilize the waveform display.
Measurements
Press the Measure/Range key to access automatic measurement functions. The device supports four automatic measurement functions and cursor measurements for precise analysis.
XY Function
The XY function allows for displaying Lissajous figures, useful for phase difference measurements between two signals.
Multimeter Mode
In Multimeter mode, the device functions as a 4 1/2 digit true RMS multimeter with 20,000 counts. It supports various electrical measurements:
- Voltage (AC/DC)
- Current (AC/DC)
- Resistance
- Diode Test
- Continuity Test
- Capacitance
Performing Measurements
Connect the multimeter leads to the appropriate input ports based on the desired measurement. Press the Auto key for automatic ranging, or use the Measure/Range key to manually select the range.

Read Hold and Relative Measurement
Use the Run/Stop key to hold the current reading. The Trig/Δ key activates the relative measurement function, displaying the difference from a stored reference value.
Memory Functions
The HO102 allows saving and recalling various data types:
- 4 sets of parameters.
- 4 reference waveforms.
- 4 images (screenshots).
- 4 sets of waveforms in CSV format.
Press the Save key to store data. Saved reference waveforms can be displayed alongside live measurements for comparison.
