Equipped with a 2.4-inch TFT display, 320*240 resolution, you can see the measurement data displayed on the screen. 2.5MHz sample rate, 200KHz actual bandwidth, 500KHz analogue bandwidth (si aves). With complete trigger function (single, normal, automatic), no matter for periodic analogue signal or non-periodic digital signal can be used freely. The measurement of the voltage signal is up to 40V. The efficient one-click AUTO function displays the measured waveform without tedious adjustment. Waveform measurements display functions that can be used to detect si aves, square waves, half-waves, sink pulse waves, etc. With one-button waveform saving feature. Only the part of the waveform that is currently being displayed can be saved. Widely applicable, it can be used in a wide ranges of applications such as automotive maintenance, appliance maintenance, teaching, and research. Note: Some of the measured signals cannot be correctly captured with AUTO and need to be adjusted manually. Firmware upgrade: To upgrade the display part, OK to turn on the machine, to upgrade the bottom part, SAVE to turn on the machine.
