1. Upgraded Oscilloscope: This oscilloscope multimeter has been upgraded to measure up to 50MHz bandwidth when using a single channel, and up to 25MHz bandwidth when using dual channels simultaneously. It can meet different measurement needs. 2. 4in1 Handheld Oscilloscope: this dual channel digital oscilloscope is a fullfeatured and highly practical oscilloscope, multimeter, flexible current clamp, and signal generator in one. The oscilloscope multimeter has onekey switching mode, automatic waveform acquisition, time base calibration, data storage, data export, data transfer port, 7 waveform outputs, afterglow time, memory and other functions, which are easy to operate and improve work efficiency. 3. 3.98inch Full view colour oscilloscope multimeter: this oscilloscope is a 3.98inch TFT full view 480320 IPS fullscreen display. It allows you to visually more enjoyable and more intuitive view of the measurement data. 4. 5000mA Battery: This oscilloscope is equipped with a 5000mA rechargeable lithium battery, which can provide longer battery life. Whether using an oscilloscope or a multimeter, there is no need to worry about battery life issues. The oscilloscope mode can last for 10 hours, and the multimeter mode can last for 20 hours. Infinitely rechargeable, no need to change batteries anymore! 5. Flexible current clamp: can support flexible coils, can measure 6000A DC current, can let you more and convenient test large current. Can be more flexible and accurate testing. The flexible current clamp can measure in hardtoreach areas without destroying wiring and without touching metal.
