Fule HW-210K Handheld Dual-channel VI Curve Tester Circuit Board Online ASA Tester

Features: *Brand new and high quality *Made of high-quality materials sturdy and durable *4 test frequencies can be used by connecting an oscilloscope both analog and digital oscilloscopes can be used. *Dual signal input and alternate display function make it easier for you to use. *4-speed frequency conversion the alternating speed is adjustable you can adjust it according to your needs. *One-click single channel/alternative display giving you a better user experience. *Do not charge the circuit board when testing it online. If there is a large capacitor on the circuit board please discharge the capacitor first otherwise it is easy to burn out the VI test board. Specification: *material: plastic *Channel: 2 channels *Frequency: 4 levels *Package size: 195*135*105mm/7.7*5.3*4.1 inches *Package weight: 435g/1.0lbs Analog oscilloscope connection method: *The connection of analog oscilloscope is relatively simple and different oscilloscopes are slightly different. *Adjust the oscilloscope to x Y mode. Some oscilloscopes have button selection while others select x Y mode with a knob. Please study on your own. *Connect the BNC cable to the oscilloscope and turn on the power. Normally a horizontal line is displayed. Adjust the xY vertical channel parameters to about 1V/div and then adjust the xY attenuation so that the horizontal line is within the display box. It can also test the version through VI. The x-attenuation potentiometer above can assist in adjusting the length of the horizontal line. If the test leads are short-circuited a vertical line will appear under normal circumstances. If the vertical line is too long or too short you need to adjust the Y channel parameters so that the vertical line is within the display frame. Half a square or 1 square on the edge is better. If the horizontal and vertical lines are normal you can enter normal measurement. How to connect a digital oscilloscope: *For digital oscilloscopes enter x Y mode through the menu or keys. The x and Y channels are adjusted to 1V/div and the single-track oscilloscope only needs to adjust the Y channel. Adjust the time base to 1-5 milliseconds. Select DC coupling for x Y channels with attenuation of 1x. *When the scope is not connected the screen should be a bright spot. Adjust the horizontal and vertical to center the highlight. Connect the VI tester. Normally it should be a horizontal line. Adjust the 103 potentiometer above the VI board to make a horizontal line appear in the display frame. half a grid or 1 grid to the edge is better. Short-circuit the test leads and the display should be vertical lines. Adjust the Y channel parameters so that the vertical line is in the display box. At this point debugging is basically over.
