Are you still puzzled in changing meter frequently? It will lead to low efficiency to hinder work and high cost in work. You need oscilloscope multimeter urgently. This 2-in-1 oscilloscope multimeter is more convenient and easy to use. Features: Digital multimeter with 200K high-speed A/D sampling, 4000 counts auto-range, one-button switch of graphical waveform display during measurement. High reliability with panel calibration technology and memory calibration, sparing the need for adjustment with potentiometer. Storing 100 sets of data and 10 waveforms independently. Capable of holding waveform and data during measurement, easy to view and analyze. Displaying historical data and real-time measurement on the same screen with particular record reading mode for easy comparison. Featuring DC/AC voltage/current, resistance, capacitance/mF (large capacitance), frequency/duty cycle, diode/continuity test. AC voltage bandwidth up to 20KHz. Innovative design for the one-key "silent mode", quiet in mastery. Frequency measurement with 5Hz~5MHz automatic switching range and the maximum input of 380VAC. 10A AC and DC current measurement with protection against voltage error. Capacitance double gear design 0.1nf-100uf gear position: convenient for small capacitors to measure quickly. 10mf gear position: high capacitance and high accuracy are guaranteed. Realizing one-button automatic waveform capture, operator-friendly to learn and operate. Effectively eliminating lead resistance, distributed capacitance or interference signals with relative value measurement (clearing). Extending battery life with automatic shutdown function.
