Zhjvihx HW-210M - 2 Channel 4 Frequency Settings

Specification: Item Type: VI Curve Tester Model: HW-210M Internal Resistor: 56Ω, 220Ω, 1KΩ, 20KΩ adjustable Frequency: 40Hz, 350Hz, 2kHz, 14Hz adjustable Material: ABS How to Use: Parameter Settings: Set the to X-Y mode (different oscilloscopes have different adjustment methods, please explores on​ your own). Adjust the vertical parameters of the X and Y channels to 1V/div, just adjust one single-channel . No need to adjust the time base for analog oscilloscopes, adjust the time base to 1-5ms for digital oscilloscopes. After correct connection, the will display a horizontal line. If a vertical line is displayed, the xY plug is reversed. Adjust the vertical and horizontal parameters so that the horizontal and vertical lines are located in the display box. Connecting an analog : Connecting an analog is relatively simple, slightly different for different oscilloscopes. Set the to xY mode. Some oscilloscopes can be selected by pressing a key, while others can be selected using the xY mode knob. Please learn on your own. Connect the BNC cable to the and power it on. Usually, a horizontal line will be displayed. Adjust the xY vertical channel parameters to around 1V/div, then adjust the xY attenuation to place the horizontal line within the display box. It can also be verified via VI test. The upper x attenuation potentiometer can help adjust the length of the horizontal line. If the test pen is short circuited, a vertical line should normally be displayed. packing list: 1 x Curve Tester 2 x Testing Pens 2 x BNC Cables
