ST-83 Self Powered, Rechargeable Dial Advance Timing Light

The ST-83 is a rechargeable dial advance timing light ideal for high performance engine timing advance measurements. The large calibrated 60o dial provides 1.5o accuracy and easy operation. Can be used on distributorless, distributor, multistrike, and marine ignition systems.

The unique RPM LED aids in timing measurements by indicating the approximate test RPM. Simply turn the indicator knob until the LED in the upper right hand corner is blinking and multiply by 100. If the indicator knob is pointing at 15, the engine is running at 1,500 RPM.

A trigger Event indicator is located on the upper left hand corner of the back panel. It will flash whenever a spark event is detected. Use the indicator to ensure you have a good spark pickup signal.

An LED on the lower left corner of the back panel indicates low battery.

The ST-83 includes a molded storage case, detachable spark pickup, charger and instruction manual.
