Capacitance ESR Inductance Resistor LC Meter Tester NPN PNP Mosfet M168 DIY Kit Description Click the to download the Manual. Product description: Before your installation process, please carefully read this instruction, which will facilitate your installation in a more rapid and accurate way. 1. Installation: The making of the casket should be finished according to the Casket Making Manual, if the casket installation is needed. The first step is the Resistance Welding. If you are not familiar with the chromatic circle, please check the resistance with the multi-meter. Next, weld the other electrical components based on , and please be aware of the size and direction of the three transistor, and the blue wiring terminal is optional: Please make sure that the direction to weld the push-button be not inversed. The normal-open point should be connected to the circuit, and the vertical line on the side of the push-button could be used as a reference: The welding direction of the LED: There is an aligned side that is the same with the PCB sign. Please note that the welding time of the LED should not be kept too long in case that the LED could be damaged: The electrode of the electrolytic capacitor should be aligned with the PCB side with a white line.After all the welding jobs have been done, please connect the electric power instead of connecting M168 and LCD, and measuring the voltage of the pin7 and pin22 on the IC plug by using the multi-meter,and the voltage should be +5V(the button should be pushed when measuring), which means the circuit and power are working in normal condition. Cut off the power, and connect M168 and the LCD which is welded with the insert pin. Be aware of the direction of IC. After all the installation, connect the power (9V battery or external 5.5-12V DC power). Push the button, and maybe the screen will light without any character display. Don°t be panic, left-right adjust the resistance to 10K and you will see the character. Adjust the character to clear type, and congratulations, the gadget could be put in use! 2. How to Use: The gadget works in a simple way. Any two pin components could be arbitrarily connected to any two of three testing points, and the transistor could be arbitrarily connected to any three terminals. Push the button, the gadget will recognize automatically the component type, pin and parameter. Components that could be measured include:Resistance, capacitance, inductor, potentiometer, diode, LED,transistor, field-effect transistor, Thyristor, and so on. Note: Please discharge the capacitance before its measurement. Otherwise the instrument will be damaged ! Electrolytic capacitor measurement. When the capacity value is greater than 2UF it will display ESR value. There is no need to distinguish the polar when connected. After the measurement the instrument will shut down automatically, press the button again the gadget will continue the measuring process. You can also press to button when it is on to start a new measurement. Please check the reliability of the components and the testing ends before the measurement. We are confident that this instrument will be of great help to you. Hope you will have delight in your DIY journey! Specification: Measurment Range: Resistor:0.5 Ω-50MΩ Capacitor:30pF-100mF Inductance:0.01MH-10H Wroking voltage: can use 6FF22 9V Battery,or DC 5.5-12V via DC socket. Controller :ATmega168 Standby current: 0.02uA Operating current: 25mA Features: 1,a key measurement operation, the time delay automatically shut off the power. Shut off the current 20 na, support for battery operation. 2,the automatic detection of PNP and NPN bipolar transistor, N, P channel MOSFET, jfets field-effect tube, diode, double diode, thyristor, resistance, capacitance and inductance. Automatically detect pin definition. 3,measure the bipolar transistor current amplification coefficient (B) and emission of conduction voltage (Uf). Darlington transistors can be high threshold voltage and high current amplification factor recognition. 4,can detect the bipolar transistor and the inside of the MOSFET protection diode and display on the screen. 5, measure the MOSFET threshold voltage and gate capacitance value. 6, support two resistance measurements, potentiometer can also be measured. If one end of the potentiometer to adjust to it, the tester is unable to distinguish between the middle and at the ends of the pin. 7, the resolution of the resistance measurement is 0.1 ohms, highest measured value up to 50 m ohm. 8, pf capacitance measurement range from 25 to 100 mf (UF) 100000. Resolution can reach 1 pF. 9, can detect more than 2 uf capacitor equivalent series resistance (ESR), a resolution of 0.01 ohms. This function for detection capacitance performance is very important. 10, two diodes can be displayed in the right direction signs, also showed a positive pressure drop. 11, LED detection for diode, positive pressure drop than normal on the high side. Double light emitting diode detection for the diode. Detection of leds will shine. 12, each test time is about two seconds, only large capacitance and inductance measurement will need a long time.
