How to Use Hanmatek HO51 Handheld Oscilloscope, Multimeter & Waveform Generator
1️⃣ What is a Handheld Oscilloscope with Multimeter and Waveform Generator?
The Hanmatek HO51 is a portable 3-in-1 device combining:
Digital Oscilloscope – Measures voltage signals and displays waveforms.
Digital Multimeter – Measures voltage, current, resistance, and continuity.
Waveform Generator – Produces test signals such as sine, square, or triangle waves.
This combination makes it ideal for field testing, electronics repair, lab experiments, and educational use. Its handheld, battery-powered design ensures portability without sacrificing functionality.
2️⃣ How it Works
The HO51 integrates multiple digital measurement and generation functions:
Oscilloscope Mode – Probes detect voltage signals; ADC converts analog signals to digital waveforms; TFT display shows real-time waveforms.
Multimeter Mode – Measures DC/AC voltage, current, resistance, and continuity.
Waveform Generator Mode – Outputs test signals to circuits for simulation or testing purposes.
Memory Storage – Allows waveform and measurement data storage for later analysis.
Trigger System – Stabilizes signals for accurate observation.
Portable Operation – Rechargeable battery allows use in the field; USB port for charging and data transfer.
Dual channels and oscilloscope allow simultaneous observation of multiple signals.
Waveform generator is useful for circuit testing and simulation.
Multimeter function consolidates measurement tools into one device.
Memory function preserves waveform data for analysis.
Portable, rechargeable design enables field testing.
4️⃣ Typical Use Cases
The HO51 is commonly used for:
✔ Field electronics troubleshooting
✔ Portable lab experiments
✔ Automotive signal analysis
✔ Embedded system testing
✔ Circuit prototyping with test waveforms
✔ Educational demonstrations
✔ Battery-powered diagnostics
✔ Signal simulation for testing devices
Example scenario:
A technician generates a 1kHz sine wave to test an amplifier input while simultaneously measuring the circuit voltage and capturing the waveform for later review.
5️⃣ How to Use the Device (Step-by-Step)
Step 1 — Power On
Recharge the device if needed and press the power button.
Step 2 — Select Mode
Choose between oscilloscope, multimeter, or waveform generator using the mode selection button.
Step 3 — Connect Probes / Leads
Oscilloscope probes to test points; ground clip to circuit ground
Multimeter leads to appropriate terminals (COM and V/Ω/A)
Waveform output to device under test
Step 4 — Adjust Settings
Oscilloscope: volts/div, time/div, and trigger type/level
Multimeter: measurement type (V, A, Ω) and range
Waveform Generator: frequency, amplitude, and waveform type
Step 5 — Observe or Output Signals
Oscilloscope: monitor waveforms on display
Multimeter: observe voltage/current/resistance
Waveform Generator: output test waveform to circuit
Step 6 — Store Data
Press memory button to save waveform or measurement data for later analysis.
Step 7 — Recharge Battery
Use USB port to recharge when battery is low.
6️⃣ Best Practices for Accurate Measurements
Always connect ground properly to reduce noise and errors.
Use short probe leads for oscilloscope measurements.
Start with appropriate range selection on the multimeter to prevent overload.
Store important waveform or measurement data frequently.
Avoid strong electromagnetic interference during measurements.
Keep battery charged for consistent performance.
