First, tester summary M328 transistor tester has been popular for many years. Not only can measure bipolar transistors , MOS FET, single triac , diodes and other semiconductor devices, but also to measure resistance, capacitance, capacitance ESR, inductors and other devices. There frequency test , the frequency of occurrence of functionality. DIY is a good helper . Because of its programs have been upgraded , more powerful . Kit includes PCB, has written a program Atmega328-PU microcontroller, 1602 display, all circuit elements all resistors, capacitors, transistors and reference voltage regulator tubes. In order to facilitate enthusiasts welding, reduce errors , the PCB with component parameters. As long as welding accurately without debugging can be successful. Figure 1.1 tester power work ( measured capacitance ) Figure 1.2 appearance coupled with the cabinet post ( measured diode ) Figure 1.3 coupled with the appearance of the cabinet after ( measured SCR ) Figure 1.4 coupled with the appearance after the cabinet (measuringcapacitance ) Figure 1.5 coupled with the appearance ( measured transistor ) cabinet post The figure above shows that : ( A ) there is a signal generator and frequency counter function ; ( 2 ) There are three components to test areas, solve small in-line components, large in-line components and SMD components testing ; Second, the main characteristics tester 1 Device Measurement Type: resistors, capacitors, inductors, diodes, bipolar transistors , FET , SCR devices ; 2 resistance measurement range : 0.01ohn~ 50M 3 capacitance measurement range : 25pF ~ 100mF, the highest resolution 1pF; capacitance values greater than 0.18uF, automatic test ESR values , Resolution 0.01; 4 inductance measurement range : 0.01mH ~ 20H, maximum equivalent resistance 2100; 5 diodes ( including single and double LED): forward voltage drop (Vf), the reverse leakage current (Ir) and junction capacitance (C); 6 bipolar transistor : automatic identification polarity (NPN or PNP), the current amplification factor (?) and forward voltage emitter junction ; 7. MOSFET or JFET: the threshold voltage (Vt) and gate capacitance values (Cgd); 8 recognize single / triac devices devices ; 9 Extended function: 0 ~ 2MHz signal generator function ; highest 2MHz frequency counter function. Third, the self-correcting process Figure 3.1 Instrument After welding , the first self- calibration to minimize errors , prepare a three foot parts are shorted Figure 3.2 The parts before starting to insert T1, T2, T3 three female holes Figure 3.3 shorted components plugged after boot Figure 3.4 into the self-test mode , where there is a question mark , then press the button Figure 3.5 After pressing the button to enter the self-test mode Figure 3.6 wait for about half a minute or so into the T4 state , suggesting unplug shorted component "T4 isolate Probe" Figure 3.7 unplug shorted components , continue to self-test. About 10 seconds after the prompt at T1 and T3 port side into more than 100nF capacitor Figure 3.8 is inserted after more than 100nF capacitor to continue self-test , after about a few seconds , the self-test is completed , suggesting the version number and the test is completed . Third, the tester running instance Payment We accept the payment via PayPal only. Payment is expected within 5 days of the auction's end.
