• Improve fault diagnosis efficiency

Easy Operation Design

The T80 is designed for automotive technicians who are unfamiliar with traditional oscilloscopes.

Features:

• Simple operation interface
• Touchscreen control
• Physical buttons
• Preset measurement options

Basic training can help beginners start waveform testing quickly.

High Sampling Rate and Large Storage

Specifications:

• Single channel sampling rate: 1G Sa/s
• Storage capacity: 4GB

Benefits:

• Capture high-speed signals
• Record long-duration waveforms
• Review waveform data repeatedly

Long-Time Waveform Recording

The large storage capacity allows continuous waveform recording.

Suitable for:

• Ignition signals
• Sensor signals
• Timing signals
• Intermittent fault analysis

Built-in Automotive Waveform Database

The T80 provides:

• 400 standard diesel engine timing waveforms

Users can compare measured signals with standard waveform references.

Waveform Raw Data Saving and Viewing

Supports:

• Raw waveform data storage
• Waveform playback
• PC viewing
• Data export

Unlike image-only storage, the T80 saves original waveform information for further analysis.

CAN Bus Analysis Function

The T80 supports CAN communication analysis.

Functions include:

• CAN waveform viewing
• CAN data collection
• CAN data saving
• CAN data parsing
• CAN data modification

Waveform Decoding

Supports waveform decoding:

• CAN
• UART
• SPI

Waveform Transmission Function

The T80 can send correct waveform signals to vehicle ECU for testing.

Applications:

• Verify timing signal faults
• Check ECU response
• Compare normal and abnormal signals

Example:

If a vehicle cannot start due to suspected timing signal failure, technicians can send a correct waveform signal to verify whether ECU activation occurs.

Multimeter Function

Built-in basic multimeter functions help technicians measure electrical signals before waveform analysis.

Benefits:

• Quickly check voltage
• Locate test points
• Capture important waveforms

Flexible Power Supply Design

Supports:

• Rechargeable battery operation
• Vehicle power supply
• Portable workshop use

The adjustable hinge and fixed bracket design allow:

• Handheld operation
• Bench oscilloscope use

4. Please Note the Following Limitations

1. Only low-voltage signal testing; cannot measure high-voltage new energy vehicle motor/battery circuits
2. Does not support LIN, FlexRay automotive bus decoding; only CAN/UART/SPI are available
3. Battery continuous working time only 1.5 hours, long-time bench testing requires vehicle cigarette lighter power supply
4. Cannot read/clear DTC fault codes or perform ECU coding/programming; it is a signal measuring tool, not a diagnostic scanner
5. Not suitable for heavy construction machinery, large marine engines and industrial equipment signal testing
6. Raw waveform storage limited to internal 4GB memory, external SD card only for data export (cannot extend real-time capture storage)
7. Does not support high-current power component load testing without matched isolation probes

5. Hardware Accessories & Licensing Requirements

• No hardware activation code, annual subscription or paid authorization; all built-in waveform library and CAN functions are unlocked out of box
• All necessary test probes, signal transmission harness and wiring terminals are included in standard package
• No mandatory extra equipment required for daily vehicle signal measurement
• PC only needed for exported waveform data viewing; no paid analysis software required

6. Software Version & Supported Operating Systems

• Independent embedded firmware on the handheld main unit, updated via Wi-Fi wireless connection
• Exported waveform data compatible with Windows 7/10/11 PC for offline viewing; Mac OS not supported
• No dedicated mobile APP; all measurement operations completed on the 7-inch touch screen
• Pre-installed full 400-set diesel waveform database, no separate software installation needed

7. Software Update

• All official firmware, waveform library and CAN protocol expansion updates are permanently free via Wi-Fi
• Free update content: add new vehicle sensor standard waveforms, optimize CAN decoding logic, fix touch and trigger bugs
• No annual update subscription fee, no free update expiration period for the whole service life
• One-click wireless upgrade without USB connection to computer

8. Global Version
