The Injectronic CJMax Labscope is based on Handspring’s Springboard expansion system. By inserting the CJMax module and loading the software, a Handspring Visor PDA can be converted into a two-channel labscope suitable for automotive use. The Palm OS touchscreen interface makes the CJMax easy to use for a variety of automotive tests, including sensors, actuators, primary and secondary ignition, low and high current and more. The software includes automatic setup information that explains how to configure the unit to measure voltage and current on common automotive circuits. Oscilloscope screenshots also can be captured and then uploaded to a PC for storage and later review.
