## Summary description

Konnwei KW870 is a handheld diagnostic meter combining an OBD2 scanner and battery tester. It reads automotive fault codes via OBD2, displays live data for troubleshooting, and performs battery condition checks. Designed for professional and DIY use, it helps identify engine and electrical issues, verify battery health, and speed up vehicle diagnostics.

## Long description

The Konnwei KW870 Diagnostic Meter is a handheld tool that combines an OBD2 scanner and a battery tester in a single unit. It reads and clears automotive fault codes, shows live data streams for engine and sensor parameters, and evaluates battery condition to support faster troubleshooting. The device is intended for both professional mechanics and DIY enthusiasts who need a compact meter to detect engine and electrical faults and to confirm battery health.
Advantages
The Konnwei KW870 provides real-time data display and fault code reading in a compact handheld form factor, allowing quick access to engine parameters and sensor readings. Its integrated battery test function offers a straightforward check of start/charge capability and voltage status, reducing the need for separate instruments. The device's user interface is designed for direct operation without extensive setup, making it suitable for rapid on-vehicle diagnostics and routine checks.
Suitable for
Reading and clearing OBD2 engine fault codes on compatible vehicles
Displaying live sensor data such as RPM, coolant temperature, and intake parameters for troubleshooting
Basic battery checks to assess voltage and starting/charging condition
Routine vehicle maintenance and pre-checks by workshop technicians
DIY car owners who perform their own diagnostics and battery inspections
When it may not be suitable
The KW870 is a focused diagnostic meter and may not replace full-featured professional scan tools that provide advanced ECU programming, bi-directional controls, module coding, or manufacturer-specific diagnostics. It also may not support non-OBD2 protocols used on some older or specialised vehicles, and advanced battery analysis functions available in dedicated battery analysers may be absent.
Key specifications
Functions: OBD2 fault code reading and clearing, live data display, battery condition testing
Display: handheld screen for live parameters and code information
Compatibility: vehicles with standard OBD2 interface and protocols (post-1996 vehicles in many regions)
Power and measurement: on-vehicle powered via the diagnostic connector; measures battery voltage and start/charge condition
Form factor: compact, portable handheld meter designed for workshop and field use
How to use
Connect the KW870 to the vehicle's OBD2 port while the ignition is in the required position, power on the unit and follow on-screen prompts to retrieve fault codes or view live data streams. For battery testing, use the designated battery test function and observe voltage and result indicators shown on the display. Read the displayed diagnostic trouble codes and follow the manufacturer's code definitions or repair manuals to interpret results. Clear codes only after repairs or when appropriate to avoid losing diagnostic information prematurely.
What to consider before purchase
Confirm that your vehicle uses a standard OBD2 connector and protocol compatible with OBD2 scanners
Decide whether you need manufacturer-specific diagnostics or bi-directional controls that this meter does not provide
Check that the battery testing capabilities meet your needs for simple voltage and start/charge checks versus advanced battery analysis
Consider whether a compact handheld form factor and basic feature set are sufficient for your workshop or home use
Usage recommendations
Use the meter with the vehicle stationary and in a well-ventilated area. Before clearing codes, record the codes and freeze-frame data for reference. For battery checks, perform the test with the vehicle at rest and accessories off to obtain accurate voltage readings. When in doubt about fault code meanings, consult service literature or a qualified technician for repair guidance.
