How to use:
Oscilloscope parameter settings.
1. Adjust the oscilloscope to X-Y mode (different oscilloscopes have different adjustment methods, please explore by yourself)
2. Adjust the vertical parameter of 2 channels of X Y to 1V/div, only need to adjust a mono oscilloscope.
3. analog oscilloscope does not need to adjust the time base, digital oscilloscope time base is adjusted between 1-5ms
4. After connected correctly, the oscilloscope will show a horizontal line. If the vertical line is displayed, the xY plug will be reversed.
5. Adjust the vertical and horizontal parameters, the horizontal and vertical lines are located in the display box.

Connection of analog oscilloscope.
1. Connecting an analog oscilloscope is relatively simple and varies slightly from oscilloscope to oscilloscope.
2. Adjust the oscilloscope to xY mode. Some oscilloscopes can be selected by pressing a button, while others can be selected by using the xY mode knob. Please learn it by yourself.
3. Connect the BNC cable to the oscilloscope and power it on. Normally, a horizontal line will be displayed.
4. Adjust the xY vertical channel parameter to about 1V/div, then adjust the x Y attenuation so that the horizontal line is in the display box. It can also pass the VI test version.
5. The x attenuation potentiometer on the upper part can help adjust the length of the horizontal line.
6. If the test pen is shorted, the vertical line will be displayed normally. If the vertical line is too long or too short, the Y-channel parameter needs to be adjusted to make the vertical line appear in the display box.
7. Half a frame or 1 frame at the edge is better. If the horizontal and vertical lines are normal, then you can input normal measurement values.

How to connect digital oscilloscope.
1. For digital oscilloscope, enter xY mode by menu or key. xY's two channels are adjusted to 1V/div, single track oscilloscope only need to adjust Y channel.
2. Adjust the time base to 1-5 ms. xY channel select DC coupling and attenuation to 1x.
3. When the oscilloscope is not connected, the screen should be bright. Adjust the horizontal and vertical orientation so that the bright spot is centered. Connect the VI tester.
4. Normally, it should be a horizontal line. Adjust the 103 potentiometer at the top of the VI board to form a horizontal line in the display frame, half a grid or 1 grid to the edge is better short-circuit test leads, at which point the display should be a vertical line.
5. Adjust the Y-channel parameters so that the vertical line is in the display frame. So far, the debugging is basically over.
6. When testing the board inline, do not charge the board. If there is a large capacitor on the board, please discharge the capacitor first, otherwise it is easy to burn out the VI test board.
