Can be used for both automotive and heavy-duty applications. No external power required - runs on rechargeable 6V SLA batter which charges when cables are hooked up to the battery. Also includes its own 120 VAC battery charger.. V-Drop Technology - This unique AutoMeter feature utilizes a patented process to automate the measurement of voltage drop in the charging circuit during starter engagement to ensure vehicle systems are operating at peak performance.. Features advanced Digital Pulse Load (DPL) technology. True-Load - This AutoMeter equipment is unique compared with other products on the market. This Tester Has The Ability To Apply A Known Significant Load (True-Load) Directly Through The Tester Connections Allowing For A More Rapid And Accurate Test Of The Vehicles Battery Starter And Charging System By The Operator. This test occurs with minimal operator effort in the short period of time required for the engine to crank over and fire.. Patented Test Process And Algorithm Allowing Operators Of This Product To Rapidly Measure A Batterys Ability To Provide Adequate Cranking Power To Start The Vehicle Without The Need For Time Consuming Manual Electrical System Load Tests.. This Provides The Ultimate In Accurate High-Speed Battery Testing When Paired With Autometers Advanced Digital Pulse Load Technology Process Reducing The Margin Of Operator Error And Workload During The Diagnosis.. Autometers V-Drop Technology Prevents The Need To Connect Additional Probes And/Or Disable Ignition Or Fuel Systems To Engage In Excessive Engine Crank Periods.. In the event that your AutoMeter tester equipped with V-Drop detects an issue it will guide the operator through the diagnosis to identify which part of the circuit is causing the excessive voltage drop.. Accurately pinpoints electrical system problems (battery starter alternator wiring and connections). Includes internal battery charger inductive amp clamp and external volt leads. Includes two seperate and specific options for automotive and heavy-duty truck applications. Quickly and accurately tests nearly all 6V and 12V batteries and battery banks up to 4 batteries and 24V (including AGM).. Features Liftgate Testing - Using Autometers Truck/Trailer Adapters The Bva-2100 Quickly Isolates Exact Truck Or Trailer Electrical System Issues Before They Become A Problem.
