1.6 in 1 Multimeter with a single panel displays voltage, current, activated power, battery energy, power frequency and power factor. - Reset function: press and hold the clear button on the front of the instrument for 5 seconds to clear the accumulated value. - Fast measurement: updates twice per second. Voltage measurement ranges are AC40-3000V; current measuring ranges are 0-100A; the effective power ranges are 0-30000W; the electrical energy ranges are 0-999999 kWh. - Colour LCD display: the digital display is clearer and more readable than before. - Why you need it: all key electrical parameters are shown on one panel, reducing the need for multiple meters and simplifying monitoring and troubleshooting. Wide voltage, current, power and energy ranges cover common household, solar and small industrial applications. A quick reset helps you track energy usage over defined periods. - Use scenarios: - Home electrical panel monitoring and energy management. - Solar or battery storage system monitoring to check performance and consumption. - On-site equipment inspection and fault finding, or verifying energy use in workshops and small facilities.
