Features and Benefits: Conductance Technology advantages make battery testing safe, fast and simple ; Proven test algorithms - also displays available power in CCAs ath 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.
