Home Arduino Module Sensor Chips About Us Description: (Pls check the selections carefully before purchase) 1. Processor using high-performance single-chip ATmega328, using external 8MHz crystal as the system clock. 2. Using 1.8-inch LCD screen with a resolution of 128X160, support 65536 kinds of colors. 3. Single key operation, support automatic shutdown for reducing power consumption. 4. Support battery power, shutdown current is less than 20nA. 5. Each measurement time is about 2s, only when measuring capacitance or inductance, the measurement time becomes longer. 6. Automatic detection of NPN, PNP bipolar transistor, N-channel, P-channel MOSFET and JFET, diode, double diode, P-IGPT, thyristor, double thyristor. For some thyristors and double thyristors, when the transistor tester can not meet the trigger current and keep the current requirements, you can not test. For some drive voltage exceeds 5V IGPT, the transistor tester can not be tested. 7. Support the identification of the test components of the pin. 8. Supports the measurement of the current amplification factor and the base-emitter conductance of the bipolar transistor. 9. By turning on the voltage and current amplification factor, you can determine the Darlington transistor. 10. Supports the gate voltage of the test MOSFET, the gate capacitance, and the drain-source on-resistance RDSon at 5V gate voltage. 11. Supports simultaneous measurement of two resistors, the data in four decimal format. Support the potentiometer test, but when the potentiometer to adjust to one end, then can not distinguish between the middle pin and the end of this pin. 12. Minimum resistance resolution of 0.01 ohms, the maximum resistance of 50M ohms. 13. A capacitor can be measured, the capacitance range of 25pf ~ 100mF, resolution 1pF. 14. Capacitors less than 25pF can be measured by connecting another known capacitor equal to or greater than 25pF, and subtracting the known capacitance from the result to obtain the measured capacitance. 15. When the test is greater than 90nF capacitor, the series equivalent resistance is also displayed, the resolution of 0.01 ohms. 16. When a capacitor greater than 5000pF is tested, the voltage loss after the test pulse can be measured, which can estimate the capacitance factor for the capacitor. 17. Supports simultaneous measurement of two diodes, additional display voltage drop of the diode. 18. Light-emitting diodes are identified as diodes, the test voltage drop is much larger than ordinary diodes. The two-color diode is identified as two diodes. 19. less than 2100 ohm resistance of its equivalent inductance is also measured at the same time, the range of 0.01mH ~ 20H, but the measurement accuracy is not very good. 20. Program with self-test function to support a variety of parameters of the calibration. 21. Support frequency generator function, by the TP2 output, the output frequency range of 1Hz to 2MHz. 22. Supports a fixed frequency signal output from TP2, you can adjust the duty cycle by pressing the button. Pay attention: Before testing the capacitor, be sure to discharge the capacitor, otherwise it may damage the test pin. When testing the components soldered on the circuit board, be sure to disconnect the power supply on the circuit board, the test device does not allow the existence of residual voltage. Hardware circuit The physical diagram is shown below, and each interface is described as follows: J1: 2.54-2PIN white seat, used to input 7 ~ 12V DC voltage; S1: red button, reset button; S2: green button, the operation button, for a key operation of the entire circuit board; Instructions for use: 1, components placed The transistor tester is very simple to use, test pin TP1, TP2, TP3 in turn. For components with only two pins, only need to be placed on any two test pins. Three test pins are placed in order for the three pins. Two resistors and two diodes can be tested simultaneously. 2, press the S1 reset button to shut down, then press the S2 key to restart the new measurement. 3, press the S2 key (greater than 1S), enter the additional function selection interface, followed by short press the button to move up and down, and then press the button to enter the corresponding function of the cursor interface. Frequency: frequency measurement function, the frequency signal from the PD4 pin input. When the input frequency is greater than 25KHz, the frequency resolution is 1Hz. Less than the value, through the measurement cycle, the frequency resolution can go to 0.001Hz; F-Generator: frequency generator function, output by the TP2, the output frequency range of 1Hz to 2MHz; 10-bit PWM: a fixed 7812.5Hz frequency signal output from the TP2, you can press the key press 1% to adjust the duty cycle, long press the button to adjust the duty cycle by 10%; C + ESR @ TP1: 3: Test the capacitance between TP1 and TP3 test pins, resulting in an equivalent input resistance. Capacitance range of 2uF ~ 50mF, can be measured continuously, long press to return to the menu interface; Resistor meter: resistance measurement; Capacitor meter: capacitance measurement; C (uF) -correction: set the large capacitance calibration parameters, that is, the output value of the actual measurement value plus or minus a certain proportion factor, the coefficient is the calibration coefficient. (Note that unless you have in-depth understanding of the function, do not arbitrarily change); Selftest: self-test function, according to prompt to complete the self-test function; Show data: display the corresponding software version of the internal use of some of the calibration parameters; Transistor: test transistor; Switch off: Enter the power off immediately Package Included: DIY Kits ATmega328p Transistor Tester 1PC*ATmega328p Diode Triode Capacitance Transistor Tester 1.8 LCD MOSFET Mini USB(DIY Kits) 1PC*Acrylic Case for ATmega328p Diode Triode Capacitance Transistor Tester(DIY Kits) Finished Products ATmega328p Transistor Tester 1PC*ATmega328p ESR Diode Triode Capacitance Transistor Tester 1.8 LCD Mini USB DIY+Case 2PCS*16 Pins Test Universal IC Socket 2PCS*16-pin 16 Pins Test Universal IC Socket 16 Pin DIP Payment Shipping Refund Payment We accept PayPal only.
