OSCILLOSCOPE FUNCTIONS
The Oscilloscope can display vehicle signals and voltages. Additionally, the Break-out
Box function uses the oscilloscope function to display any ECU signal which is available
from the Break-out Box.
The Oscilloscope and Autoprobe can measure voltage from -20 volts to +20 volts and
frequency from 0-5 KHz for frequency counter and 0-10 KHz for oscilloscope.
Refer to the OBD Operator's Manual for detailed Autoprobe and Oscilloscope operating
instructions.
