# Title: Hantek HT25COP Coil-on-Plug Signal Probe for Automotive Ignition Analysis ## Description: Professional Automotive Ignition Diagnostics The Hantek HT25COP is a specialised capacitive probe designed for non-intrusive testing of coil-on-plug (COP) ignition systems. This professional diagnostic tool enables engineers to capture secondary ignition waveforms directly from the ignition coil without requiring cable extensions or system modifications. Advanced Coil-on-Plug Testing Modern vehicles increasingly use COP ignition systems where individual coils mount directly onto spark plugs, eliminating traditional high-voltage spark plug wires. The HT25COP probe addresses this diagnostic challenge by coupling magnetically to the coil's electromagnetic field, enabling oscilloscope analysis of the ignition waveform. Probe positioned on ignition coil in engine bay Technical Operation The probe operates through capacitive coupling, detecting the high-voltage discharge patterns within the ignition coil. When connected to an oscilloscope via the standard BNC connector, engineers can analyse: Firing line voltage and duration Spark burn time and intensity Coil oscillations and decay patterns Misfire detection and timing anomalies Wiring Quick-Start Connection requires no vehicle modification: Connect BNC plug to oscilloscope Channel A Attach ground clip to engine earth point Position probe sensor against target ignition coil Configure oscilloscope: 5-15kV range, 10-20ms timebase Set trigger: rising edge, 2-4kV threshold Safety Warning: Ensure probe insulation is intact before use. Keep away from moving engine components and high-temperature surfaces. Diagnostic Applications Condition Waveform Indication Normal Operation Clean firing line, consistent burn time 1.5-2ms Misfire Reduced or absent firing line, extended oscillations Carbon Tracking Multiple firing events, erratic burn patterns Lean Mixture Increased firing voltage, shortened burn time Compatibility Compatible with most automotive oscilloscopes featuring BNC inputs. Works effectively with Hantek automotive scopes, PicoScope units, and other professional diagnostic equipment. The 2-metre cable length provides sufficient reach for most engine bay configurations. Professional Tip: For optimal results on V-configuration engines, the flexible probe arm allows positioning in confined spaces where rigid probes cannot reach. ## Product type: Automotive Test ## Vendor: Hantek Electronic Co Ltd ## Tags: Accessory, Automotive, Hantek, hantek-electronic-co-ltd, High Voltage Probe, Oscilloscope, Oscilloscope Probe, spec-oscilloscope-probe, Test Probe ## Price range: 100.0 - 100.0 GBP ## Link: https://thedebugstore.com/products/hantek-ht25cop-coil-on-plug-and-signal-probe-uk ## Options - Title: Default Title ## Collections - [New Products](https://thedebugstore.com/a/llms/collections/new-products-debug-store) - [Oscilloscopes](https://thedebugstore.com/a/llms/collections/oscilloscopes-catalogue-uk) - [Hantek Electronic Co.

It's also effective on conventional ignition systems with accessible high-voltage leads. Compatible with petrol engines from motorcycles to commercial vehicles. - 1572843: Does the HT25COP require specific oscilloscope settings?***SIMP***Recommended settings: voltage range 5-15kV, timebase 10-20ms, trigger on rising edge at 2-4kV threshold. Most automotive oscilloscopes include preset ignition modes that work effectively with this probe. - 1572844: How does the probe attach to the ignition coil?***SIMP***Simply position the sensor paddle against the coil housing - no physical connection required. The flexible arm allows positioning at various angles. Magnetic coupling occurs through the coil's electromagnetic field during firing. - 1572845: Can this probe detect misfires and timing issues?***SIMP***Yes, the HT25COP captures complete secondary waveforms showing firing voltage, burn time, and decay oscillations. Misfires appear as reduced or absent firing lines, whilst timing issues show irregular patterns across cylinders. - 1572846: What's the difference between this and primary ignition testing?***SIMP***Secondary testing shows actual spark formation and combustion chamber conditions, whilst primary testing only shows coil switching. Secondary waveforms reveal spark plug condition, mixture strength, and combustion quality that primary testing cannot detect. - 1572847: Is the probe suitable for hybrid and electric vehicles?***SIMP***The HT25COP works on any petrol engine regardless of vehicle electrification level. However, ensure proper earthing and follow manufacturer safety protocols when working on hybrid systems. - 1572849: How do I interpret abnormal waveform patterns?***SIMP***Normal waveforms show clean firing lines (5-15kV) followed by 1.5-2ms burn time. High firing voltage indicates worn plugs or lean mixture; extended burn time suggests rich mixture; multiple firing events indicate carbon tracking or insulation breakdown. - 1572850: Can the probe be used for injector testing?***SIMP***Yes, the HT25COP can detect electromagnetic pulses from fuel injectors and other inductive actuators. Position the probe near the injector solenoid to capture switching waveforms for diagnostic analysis. - 1572851: What safety precautions are necessary during testing?***SIMP***Ensure probe insulation integrity before use. Keep away from moving belts, fans, and hot surfaces. Never touch coil terminals during operation. The probe provides electrical isolation but standard automotive electrical safety practices apply. - 1572852: How does this compare to more expensive diagnostic probes?***SIMP***The HT25COP offers excellent value whilst providing core functionality of premium probes. Differences mainly involve build quality, sensitivity range, and included accessories. For professional automotive diagnostics, performance is comparable to probes costing significantly more.
