300V100A Digital DC Voltmeter Ammeter Power Meter Battery Tester Multi Function Power Meter

Note: If measuring below 7.8V needs an external voltage of 4-30V. If the voltage exceeds 30V, the product will be burnt out. Although the DC voltage meter has reverse connection or short-circuit protection, but there is no protection in the independent power supply it is directly power supply to the device, if connect high-voltage will burn motherboard and display will not show. Feature: Can test voltage range 0-300V, current range 0-100A, test power even up to 30,000W, high voltage rechargeable batteries, or low voltage 18650 battery. Support current, voltage, capacity accumulation, power accumulation, power, impedance, temperature, time eight data screen display.
