Function introduction
Capacitance Meter, Inductance Meter, Frequency Meter based on 51 microcontroller, powerful enough to measure all kinds of non-polarised capacitance, polarised capacitance, inductance and frequency.
Instructions for use
When first powered on, the LCD screen will have a white screen of about 2 seconds. This is because the program is designed in this way. The 2-second power on system calculates some initial references needed for subsequent measurements. In the white screen range, except for the power switch that is pressed, all other switches are required to pop up. If a switch is pressed, the subsequent measurement data will be inaccurate. Remember !!!
After 2 seconds of white screen, the LCD will display: F/C/LTester, and you can start measuring the parameters of the component you want.
If measuring non-polar capacitance, connect the non-polar capacitor and press the "Test switch for non-polar capacitance". If measuring inductance, connect the inductance and press the "Inductance Test switch". Only one of the five function switches can be pressed at the same time. Press whatever is tested, and any unused requirements will pop up.
When testing non-polar capacitors, inductors, and polarized capacitors, these components are connected to the test socket without distinguishing polarity. Frequency testing requires distinguishing polarity, and attention should be paid.
If you need to adjust the brightness of the liquid crystal for the first time after purchasing the kit and welding, adjust t
