SMAKN Inductance Resistor Transistor Tester Capacitor ESR LCR Meter NPN PNP Mosfet
Affect the accuracy of related resistance using metal film resistor, one over one thousand the rest also USES one percent metal film resistor. Use 1602 LCD screen LCD, can also according to the measurement data and graphics. The main chip USES dual in and with a socket, very suitable for electronic enthusiasts update or replace the chip. Use 9 V laminated batteries. All the components are made of high quality quality goods. LCD screen for low-power backlit screen, backlight current about 2mA, so after startup time have a backlight, convenient to use in the dark. Function is introduced: One -button operation, automatic shutdown. Only 20nA shutdown current. Automatically detect NPN, PNP bipolar transistors , N -channel and P -channel MOS FET, JFET , diodes , two diodes, thyristors small power unidirectional and bidirectional thyristor. Automatic identification components pin arrangement . Measuring bipolar transistor current amplification factor and base - emitter threshold voltage. Through the base - the threshold of the emitter voltage and high current amplification factor identification darlington transistors. Can detect the protection of the bipolar and MOS transistor diode. Measurement of MOS field effect tube grid threshold voltage and gate capacitance. Can be measured at the same time two resistance and resistance to symbols displayed. On the right shows with four decimal values. Resistance symbols on both sides of the display pin number. Can therefore be measured potentiometer. If the potentiometer sliding side will not be transferred to an extreme position, can distinguish between the intermediate and pins at both end and ect.
