About DollaTek DIY GM328 Transistor Tester LCD Diode

Features:Automatically detects NPN and PNP transistors, FET, diodes, dual diode, thyristor, SCR, automatic identification of the transistor pinout.Test NPN and PNP transistor common-emitter current amplification factor, the base-emitter threshold voltage, off the collector - emitter leakage current.Support 2 resistors measurement, show its positive and negative, on-state voltage.Resistance measurement maximum resolution 0.01Ω, can be measured up to 50MΩ.Automatically test the pins of a component and show on the display.Measure FET gate threshold voltage and gate capacitance.For the following 2100Ω resistor while measuring its inductance measuring range from 0.01mH - 20H.Can be used as signal generator and frequency meter: frequency range from 1Hz-2MHz and can generate 1%-99% PWM(pulse width modulation) signals.Notice: Before measuring capacitance, the capacitor must be discharged, otherwise very likely damage the meter.Specifications:Type: Assembled Tester / DIY Kit(Optional)Display: 160*128 LCDPower Supply: 1 * 9V Battery(not included); DC 6.8-12V Current: Approx. 30mAPower Supply: 1 * 9V Battery(NOT Included)Resistance Measurement: Max. 50MΩResistance Resolution: 0.01ΩCapacitance Measurement: 25pF~100mFCapacitance Resolution: 1pFDC Voltage Measurement: Up to 50VScreen Size: 3.7 * 3cm / 1.45 * 1.18inPCB Size: 7.8 * 6.2cm / 3.1 * 2.44inProduct Weight: 66g / 2.3ozPackage Weight: 69-73g / 2.45-2.57ozPackage List:1 x DollaTek Transistor Tester DIY Kit(Battery not Included)
