Dual-channel Vi Curve Tester Circuit Board Online Detection Tester Dual-channel Vi Curve Tester

4 test frequencies, can be used when connected to an oscilloscope, both analog oscilloscopes and digital; oscilloscopes can be used; Dual signal input, alternating display; 4- frequency, alternating speed adjustable; One click on single channel \/ alternating displayHOW TO USE:Oscilloscope parameter setting: Adjust the oscilloscope to X-Y mode(different oscilloscopes have different adjustment methods, please explore by yourself). Adjust the vertical parameters of the 2 channels of X Y to 1V\/div, and only one of the single-track oscilloscopes needs to be adjusted.The analog oscilloscope does not need to adjust the time base, the digital oscilloscope time base is adjusted between 1-5msAfter the connection is correct, the oscilloscope will display a horizontal line. If a vertical line is displayed, the xY plug will be reversed. Adjust the vertical and horizontal parameters, the horizontal and vertical lines are in the display box. of connecting analog oscilloscope:The analog oscilloscope connection is relatively simple, and different oscilloscopes are slightly different.Adjust the oscilloscope to xY mode. Some oscilloscopes can be by pressing the buttons, while others are by the knob to xY mode. Please study by yourself.Connect the BNC cable to the oscilloscope and on. Normally, a horizontal line will be displayed. Adjust the xY vertical channel parameters, about 1V\/div, and then adjust the x Y attenuation so that the horizontal line is in the display frame. It can also pass the VI test version. The x attenuation potentiometer on the upper side can assist in adjusting the length of the horizontal line. If the test pen iis short-circuited, a vertical line will be displayed under normal circumstances. If the vertical line is too long or too short, you need to adjust the Y channel paramet to make the vertical line in the display frame. Half grid or 1 grid to the edge is better. If the horizontal and vertical lines are normal, you can enter the normal measurement.Material:plasticcolour:blackPackage Contents:1 * Tester1 Pair * BNC cable1 Pair * test cableOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
