Product DescriptionTransistor Tester Replacement TFT LCD GM328 Accessories Useful Durable Product description:100% brand new and high qualityMade of high-quality materials, durableThe one-chip computer uses ATMEAG328P DIP-28. With IC holderThe display unit adopts 160x128 pixel color display, full-screen characters 8x20, 16-bit color depth, graphic display element symbolsRotary switch control, one-key measurement, automatic shutdownUse 9V laminated battery, you can also use power adapter (DC 6.8-12V), the current of the whole machine is about 30mA, and the current after shutdown is about 20nAAutomatic detection of NPN and PNP transistors, field effect transistors, diodes, double diodes, thyristors, thyristors, and automatic identification of transistor lead wiresTest NPN and PNP transistor common emitter current amplification factor, base-emitter threshold voltage, turn-off collector-emitter leakage currentPole-pass transistor base-emitter threshold voltage and high current gain identification Darlington transistorBuilt-in detection power transistor and FET protection diodeTest FET gate-source threshold voltage conduction, drain-source conduction resistance, gate-source capacitanceAt most two measuring resistances, so you can measure the three-pin adjustable resistance. If you adjust the adjustable resistance to the end, it can only be one measured resistance value.The maximum resolution of resistance measurement is 0.01Ω. Can measure up to 50MΩCapacitance measurement range 25pF-100mF, resolution 1pFMeasure the equivalent series resistance (ESR) of capacitors greater than 90nF at the same time. The maximum resolution of the equivalent series resistance is 0.01ΩCapacitors larger than 5000pF also show the rate of decrease after charging, and the capacitance value can reflect the quality factor (Q value)Measure up to two diodes to show their positive and negative, on-state voltageThe LED also displays a graphic symbol diode, which has a much higher turn-on voltage than ordinary diodes.Reverse breakdown voltage lower than 4.5V can be detected by Zener diode, which is shown as a double diode symbol. The positive and negative voltages are subject to the diode symbol of about 700mV, and the voltage corresponding to the second diode symbol is turned on and adjusted. So don’t measure an ordinary diode and a Zener diode at the same timeTest a single diode, and the PN junction capacitance between the test reverse junction and the reverse junction capacitance between the PN junction capacitance of the transistor under test can only enter the base and emitter, base and collector of the transistor at the same time.To test the capacitance of less than 25pF, you need to prepare a 30pF capacitor during the test, and then test the 30pF capacitor. After the test, connect the capacitors in parallel and measure again, and subtract the measured result from the measured value of the 30pF capacitor.For the following 2100Ω resistors, measure their inductance at the same time. The measurement range is from 0.01mH-20HAbout two seconds during the test, large capacitance and inductance will take longerAdditional functions include frequency measurement, voltage measurement, square wave generator, PWMGenerator, color selection, debugging and calibration, continuous testing and other functionsThe frequency range is from 1Hz to 1MHz or higher, measured at a frequency below 25kHz, and the display cycle resolution is up to 0.001mHzDC voltage measurement up to 50VOne square wave signal output, multiple frequencies to choose from, the maximum output frequency is 2MHzOutput a fixed frequency, variable duty cycle pulse signal (PWM), the duty cycle is adjustable from 1% to 99%Apacitance function test, the test mode of continuous measurement of 2uF-50mF capacitance can be directly measured in its circuit (the measured capacitance needs to be energized in the circuit, and the measured capacitance needs to be fully discharged)Thyristors and thyristors can only identify their lead wires. It is also necessary to test whether the trigger current of the thyristor or thyristor is less than the current that the tester can provide. The tester can only provide a maximum of 6mA trigger current1. Turn off2. Transistor test3. Frequency test4. f-generator5. 10-bit pulse width modulation6. C+ESR@TP1:37.
