Application - Measure up to 12 parameters: VPP, VP, Vmax, Vmin, Vavg, Vrms, frequent, duty+, duty-, time+, time-, period. FFT display function can analyze the spectral characteristics of the signal. Equipped with a USB interface that can be connected to a computer to share its screenshots with the computer, which is convenient for secondary analysis6000mAh Battery: Built-in 6000mAh rechargeable lithium battery, fully charged for 4 hours of continuous operation at high screen brightness. The cursor measurement function makes it easy to measure periods, frequency and voltage manuallySmart Display: 7 inch TFT LCD screen with 800 x 480 resolution, vivid color and high contrast. Capacitive touch screen, just like the touch screen of a modern mobile tablet, is not a resistive touch screen with old-fashioned fingernail operationMulti-function - One-touch waveform memory and screenshot. Built-in 1GB memory - Can store up to 1000 screenshots + 1000 sets of waveform data - This powerful waveform image manager supports searching, viewing and detailed viewing. It supports page turning, deleting, enlarging, reducing and moving waveforms, among other functionsIntelligent Anti-Burn Device - 1x supports voltage up to 400V. 100MHz analog bandwidth at 1GSa/s sampling rate (1X = 5MHz, 10X = 100MHz). High measurement range: 1X can measure 0 - 40V, 10X can measure 0 - 400V, 100X can measure 0 - 4000V
