Profitester with integrated printer for quick and precise results. Features: - 12V battery: measures voltage and charge status. - Starter 12 and 24V: measures starting voltage. - Alternator 12 and 24V: measures the output voltage of the alternator. - Special function for measuring the internal resistance of the battery. - Integrated thermal printer for printing test results. Quick analysis: - Battery voltage (6V to 30V). - Available starting current. - Battery charge status (%). Battery types: Suitable for three different lead-acid battery types from 30 to 200Ah: - maintenance-free batteries VRLA / GEL / AGM FLAT / AGM SPIRAL. - Standard flooded batteries. - START / STOP batteries (EFB/AGM). Accurate: Automatic temperature compensation. - Dynamic resistance measurement minimizes battery discharge and provides an unaltered result that is not affected by: - Surface charge. - Power consumption from loads (various LEDs, etc.). - Faulty connections (oxidation of terminals/connectors, loose terminals). Practical: - Adjustable display brightness. - Complete test report with date, time, name, etc. - Replaceable measuring leads. - Standby function. - Multilingual software. - Reverse polarity protection. - ABS housing (acid-resistant) + shock protection. - Power supply: 1 9V battery.
