Oscilloscopes can perform a battery, starting motor, and alternator test in a single automated test.
While Oscilloscopes have a plethora of important features that enable the user to zoom, measure, scroll, and scale through events in the blink of an eye,
we often overlook the fact that this processing capacity may be put to good use in the form of an automated test battery life as well.
It can test three primary components that can all be liable for battery failure utilizing a single test lead linked across your battery and a high-amp current clamp connected around the main battery power line.
Once the engine is started, the software will monitor the initial battery voltage, the voltage decreases while cranking, the starting motor current usage, and the battery recovery/charge rate.
