Frequently asked questions

The scopemeter feature allows you to display two signal waveforms, which is very useful for diagnostic purposes.

The scopemeter feature can display various signals, including coil drive, crankshaft position sensor, injector drive, manifold absolute pressure (MAP), throttle position (TPS), vehicle speed sensor (VSS), tach signal, idle air control (IAC), and exhaust gas oxygen (EGO) sensor signals.

To use the scopemeter feature, connect the probes to the desired signals, select the appropriate voltage range and time base settings, make sure the Twin Scan 3 has power, and click on View Scopemeter Data on the View menu.

The scopemeter feature has two voltage range selections: low (0-20V), suitable for most signals, and high (±200V), required for signals like crankshaft position sensor, coil drive, and injector drive.

The time base setting determines the time scale of the waveform display. You can select different time bases in milliseconds per division (msec/div), allowing you to zoom in or out on the waveform.

You can select which channel and signal edge (rising or falling) the unit will trigger on. The trigger point is at 20% of the horizontal time scale.

The scopemeter feature has three operating modes: Run, Stop, and Single. In Run mode, the unit continuously captures new signal data. The Stop button freezes the last captured data. Each time you click the Single button, one signal waveform is captured.
