Version GM328A Transistor Tester Diode Capacitance ESR Voltage Frequency Meter PWM Square Wave Signal Generator Soldering

Description: Digital LCD display for easy readings, can display measured data and graphics. Rotary switch control, a key measurement for convenient use. Main chis the DIP, easy for electronic enthusiasts to DIY or update the main . Use 9V battery(not included), can also use DC power(DC 6.8-12V). Automatic shutdown, shutdown current is only about 20nA. Automatically detects NPN and transistors, FET, diodes, dual diode, thyristor, SCR, automatic identification of the transistor pinout. Test NPN and 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 0.01, can be measured up to 50M. 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: Display: 160*128 LCD Power Supply: 1 * 9V Battery(not included); DC 6.8-12V Current: Approx. 30mA Resistance Measurement: Max. 50M Resistance Resolution: 0.01 Capacitance Measurement: 25pF~100mF Capacitance Resolution: 1pF DC Voltage Measurement: Up to 50V Screen Size: 3.7 * 3cm / 1.45 * 1.18in Size: 7.8 * 6.2cm / 3.1 * 2.44in Package Included: 1 x GM328 Mega328 Transistor Tester LCR Diode Capacitance ESR Voltage Frequency meter PWM Square wave Frequency Signal Generator
