Features Function: Digital DC voltmeter ammeter can measure DC voltage, current, power, energy consumption and display it on a large LCD screen, with high recognition under direct sunlight. High-quality Performance: The ampere meter is small in size and can display real-time voltage and current values on the same screen at the same time, and the measured DC voltage and DC current are completely isolated inside the instrument. Wide range of Measuring Voltage and Current: DC voltage: DC0-199.9V; DC current: DC0-10.00A. High Reliability: High resistance to current impact, the ammeter will not be damaged by current impact. Wide Range of Applications: DC volt amp meter tester is suitable for chargers, inverters, solar energy, wind turbines, LED metering, etc. Specification: Item Type: Voltage Current Meter Measurement Accuracy: 1% ± 2-digitDisplay: LCD Liquid Crystal Display Measuring Range: DC Voltage: DC0-199.9V DC Current: DC0-10.00A Power Consumption: <0.5VA Measuring Speed: About 2 Times Per Second Working Power Supply: AC220V±10% Installation Size (Length x Width): Approx. 68 x 38mm / 2.7 x 1.5in (Embedded Installation) Package List: 1 x Voltage Current Meter1 x User Manual Note: This instrument power supply voltage must be pure sine wave voltage to power the instrument (modified sine wave and square wave will burn the instrument!!! ) Package List 1 x Voltage Current Meter 1 x User Manual
