Digital LCD display for easy readings, can display measured data and graphics.<br> Rotary switch control, a key measurement for convenient use.<br> Main chip is the DIP, easy for electronic enthusiasts to DIY or update the main chip.<br> Use 9V battery(not included), can also use DC power(DC 6.8-12V). Automatic shutdown, shutdown current is only about 20nA.<br> 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.<br> <br> Support 2 resistors measurement, show its positive and negative, on-state voltage.<br> Resistance measurement maximum resolution 0.01, can be measured up to 50M.<br> Automatically test the pins of a component and show on the display.<br> Measure FET gate threshold voltage and gate capacitance.<br> For the following 2100 resistor while measuring its inductance measuring range from 0.01mH - 20H.<br> Can be used as signal generator and frequency meter: frequency range from 1Hz-2MHz and can generate 1%-99% PWM(pulse width modulation) signals.<br> Notice:<br> Before measuring capacitance, the capacitor must be discharged, otherwise very likely damage the meter.<br> Specifications:<br> Display: 160x128 LCD<br> Power Supply: 1x9V Battery(not included); DC 6.8-12V<br> Current: . 30mA<br> Resistance Measurement: Max. 50M<br> Resistance Resolution: 0.01<br> Capacitance Measurement: 25pF-100mF<br> Capacitance Resolution: 1pF<br> DC Voltage Measurement: Up to 50V<br> Screen Size: 3.7x3cm/1.45x1.18in<br> Note:Due to different production batches, there is a slight color difference, which does not affect the use.<br> Colour:Red<br> Material:ABS+electronic components<br> <br> Package Contents:<br> 1 * transistor tester<br> 1 * protective case with yellow protective paper<br> <br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
