Tests 6V and 12V flooded and AGM batteries rated between 100-1600 CCA or 10-265 AH. Tests starting/charging circuits discharged batteries and detects bad cells.. Unlike competitor models AutoMeter testers only require a single technician to run a full electrical system test due to our on-board 120 amp True Load cell.. Advanced Digital Pulse Load (DPL) technology. True-Load - 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 eliminates the need to apply inconsistent loads such as headlights fans etc.. 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.. which makes our products easier to use and more accurate.. Automatically stores results of last 150 completed tests for easy review. Wirelessly communicates to optional test results printer via infrared or outputs to PC via AC-12 cable.. English and Spanish language menus and test results.. Charging system test results measure alternator current output voltage regulation and diode ripple delivering a pass or fail result.. 16 Gauge 20" leads with professional grade clamps that are easily field serviceable.
