3. Setup
3.1 Charging the Device
Before initial use, fully charge the MHO14-200. Connect the provided power adapter to the DC 12V input port on the device and plug it into a standard power outlet. The integrated 16000mAh lithium-ion battery supports extended runtime and can also be charged via a power bank for field portability.
3.2 Connecting Probes and Leads
For oscilloscope measurements, connect the passive probes to the BNC input channels (CH1, CH2, CH3, CH4) on the front panel. Ensure a secure connection by twisting the BNC connector until it locks. For multimeter functions, connect the multimeter leads to the dedicated input jacks (VΩmA, COM, 10A) on the front panel, matching the color coding (red for positive, black for common).
3.3 Powering On/Off
To power on the device, press and hold the power button located on the side or front panel until the display illuminates. To power off, press and hold the power button again until the shutdown prompt appears, then confirm. A short press typically puts the device into standby mode.
4. Operating Instructions
4.1 Oscilloscope Mode
The MHO14-200 functions as a 4-channel oscilloscope with a 200MHz bandwidth and 1GSa/s sampling rate. It features a 12-bit ADC for high vertical resolution, capturing subtle signal details with 4096 steps of signal quantization. The 110Mpts memory depth allows for extended waveform capture. Use the dedicated vertical and horizontal controls, along with the touchscreen, to adjust settings such as voltage per division, time base, and trigger levels.

5. Maintenance
5.1 Battery Care
To maximize the lifespan of the integrated 16000mAh lithium-ion battery, avoid fully discharging it frequently. Recharge the device when the battery level is low. Store the device in a cool, dry place if not used for extended periods, ideally with a partial charge (around 50%). The battery is designed for 1000+ charge cycles.
5.2 Cleaning
Clean the device regularly with a soft, dry, lint-free cloth. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaning solution. Do not use harsh chemicals, solvents, or abrasive cleaners, as these can damage the screen or casing. Ensure all ports are dry before use.
5.3 Storage
Store the MHO14-200 in a clean, dry environment away from extreme temperatures, direct sunlight, and high humidity. The shock-absorbing rubber casing provides impact resistance, but proper storage in a protective case is recommended when transporting the device.
