Purkeys’ Handheld Electrical Analyzer is designed for testing the electrical systems of heavy-duty trucks. The analyzer has a menu-driven system formatted to guide users through tests of starting, charging and battery systems and to help simplify identifying and troubleshooting issues. The portable lightweight design allows the tester to be used in the shop or on the road. It has multiple leads and can apply 40 to 120 amps for automated load tests while also checking for voltage drop. The device is optimized for both flooded-cell and absorbed glass mat batteries and can record its testing history with printable results.
