Conductance Technology advantages make battery testing safe, fast and simple. Proven test algorithms - also displays available power in CCA's at the end of each test. High and low voltage capture for improved starter/charger system testing. Tests discharged batteries. Proven reliability and durability With an innovative design made in the USA, this analyzer features endorsed or required technology by virtually every automotive OEM. Building upon the success of the PBT-100, the first battery conductance tester built for the professional technician's toolbox, the PBT200 offers these additional capabilities: shows available power in CCA in addition to condition and voltage, bad cell detection, advanced starter testing - down arrow displays the captures low voltage from cranking the engine for simple starter analysis. Advanced starter testing - using the up and down arrows while the engine is running displays the captured high and low voltage for simple alternator/regulator analysis.
