About this item

• Upgrade Version --- Clearer Display, Volt Amp Curve, Wider Measuring Range, Temperature Measure Function.
• 9-IN-1 MULTIMETER --- measure and display voltage (0-120V), current (0-50A)(0-100A)(0-300A), power, battery capacity, amp-hour, watt-hour, time simultaneously, temperature, and charging figure
• APPLICATION --- can be used as battery charge-discharge tester meter for automobile and car battery; as battery capacity monitor for photovoltaic system; as voltage meter, current meter, power meter, etc.
• BIDIRECTIONAL AMMETER --- the multimeter can detect current in dual direction without changing the wiring direction when used for monitoring charging and discharging.

• PROTECTION --- over-voltage protection, over-current protection, over-power protection, over-charged protection, time limitation, over temperature, etc.
