51 Single-Chip Microcomputer Inductance and Capacitance Frequency Meter DIY Electronic Kit for Welding Practice Popis

When you first power , the LCD will have a white screen of about 2 seconds. This is because the program is designed in this way. The system will calculate some initial references needed for the subsequent measurement after power- for 2 seconds. In addition to the power being pressed, other switches in the white screen range are required to . If the is pressed, the subsequent measurement data will be inaccurate. Remember!
After 2 seconds of white screen, the LCD will display: F/C/L Tester, and then you can start to measure the parameters of the components you want.
For example, to measure the non-polar capacitance, connect the non-polar capacitance and then press the "test of non-polar capacitance". For example, to measure the inductance, connect the inductance and then press the "inductance test ". Only one of the five function switches can be pressed at the same . When testing what is pressed, the requirements that are not used will .
When testing nonpolar capacitors, inductors, and polar capacitors, these components are connected to the test stand regardless of polarity. For frequency testing, it is necessary to distinguish polarity. Note that.
If it is the first to use the purchased kit after welding, you need to adjust the brightness of the LCD. After 2 seconds of power , adjust the 10K potentiometer the top of the board to make the display effect of the 1602 reach a better state.
