ITEM NAME:Gm328A Transistor Tester Diode Capacitor Esr Volt Frequency Meter Pwm Diy T L5Z7 Gm328A Transistor Tester Diode Capacitor Esr Volt Frequency Meter Pwm Diy T L5Z7 Digital LCD display for easy readings, can display measured data and .Rotary switch control, a key measurement for convenient use. Main chip is the DIP, easy for electronic enthusiasts to DIY or update the main chip. Automatic shutdown, shutdown current is only about 20nA. 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. Automatically test the pins of a component and show on the display. Measure FET gate threshold voltage and gate capacitance. For the following 2100 ohm 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. Display: 160 x 128 LCD Power supply: 1 x 9V battery(not included); DC 6.8-12V Current: approx. 30mA Resistance measurement: Max. 50MΩ Resistance resolution: 0.01 ohm Capacitance measurement: 25pF~100mF Capacitance resolution: 1pF DC voltage measurement: Up to 50V colour:Photo Color Material:PC+ metal size:Screen size: 3.7 x 3cm / 1.45 x 1.18 inch PCB size: 7.8 x 6.2cm / 3.1 x 2.44 inch Package Contents: 1 x GM328A Transistor Tester Caution: before measuring capacitance, the capacitor must be discharged, otherwise may damage the meter.
