Multi-use Diode Capacitance Voltage Meter Transistor Tester DIY Kit PWM Square Wave Signal Generator +DIY Acrylic Case

["Description:\nbrand new and high quality\nFeature:\nMulti-functional transistor tester for automatic detection of NPN and PNP transistors, FET, diodes, dual diode, thyristor, SCR, automatic identification of the transistor pinout. It also can be used as square signal and PWM signal generator.\nDigital LCD display for easy readings, can display measured data and graphics.\nRotary switch control, a for key measurement for convenient use.\nMain chip is the DIP, easy for electronic enthusiasts to DIY or update the main chip.\nUse 9V battery(not included), can also use for DC power(for DC 6.8-12V).\nAutomatic shutdown, shutdown current is only about 20nA.\nAutomatically detects NPN and PNP transistors, FET, diodes, dual diode, thyristor, SCR, automatic identification of the transistor pinout.\nTest NPN and PNP transistor common-emitter current amplification factor, the base-emitter threshold voltage, off the collector - emitter leakage current.\nSupport 2 resistors measurement, show its positive and negative, on-state voltage.\nResistance measurement maximum resolution 0.01Ω, can be measured up to 50MΩ.\nAutomatically test the pins of a component and show on the display.\nMeasure FET gate threshold voltage and gate capacitance.\nFor the following 2100Ω resistor while measuring its inductance measuring range from 0.01mH - 20H.\nCan be used as signal generator and frequency meter: frequency range from 1Hz-2MHz and can generate 1%-99% PWM(pulse width modulation) signals.\nAttention: Before measuring capacitance, the capacitor must be discharged, otherwise very likely damage the meter.\n\nSpecifications:\nItem Type: Transistor Tester\nMaterial: PC\nSize: outer shell: 90x78mm/3.5x3.07in\nColor: As shown\nDisplay: 160x128 LCD\nPower Supply: 1x9V Battery(not included); for DC 6.8-12V \nCurrent: Approx. 30mA\nResistance Measurement: Max. 50MΩ\nResistance Resolution: 0.01Ω\nCapacitance Measurement: 25pF-100mF\nCapacitance Resolution: 1pF\nfor DC Voltage Measurement: Up to 50V\nQuantity: 1 Set\n\nNote:\nNo retail package.\nTransition: 1cm=10mm=0.39inch\nPlease allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.\nDue to the difference between different monitors, the picture may not reflect the actual color of the item.
