NEW Function

Automatic detection of NPN and PNP transistors, N-Channel and P-Channel MOSFET, Diode (including double Diode), Thyristor, Transistor,Resistor and Capacitor and other components

 Automatic test the pin of a component, and display on the LCD

Can detect the transistor, MOSFET protection diode amplification coefficient and the base to determine the emitter transistor forward biased    voltage

 Measure the gate and gate capacitance of the MOSFET threshold voltage

 Use 128*64 liquid crystal display with green backlight

Specifications: For you reference

 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

 Via the base - emitter threshold voltage and high current amplification factor to identify Darlington transistors

 Can detect bipolar transistors and MOS transistors protection diodes

 Measuring the gate MOS FET threshold voltage and the gate capacitance

 Can simultaneously measure two resistors and resistor symbol is displayed. Displayed on the right with a decimal value of 4. Resistance symbol on both sides shows the pin number. So you can measure the potentiometer. If the potentiometer wiper is not transferred to an extreme position, we can distinguish the middle and both ends of the pin

Resistance measurement resolution is 0.1 ohms, 50M ohms can be measured

Can measure capacitance can measure capacitance of 30pF-100uF, resolution 1pF

 2uF more capacitors can simultaneously measure the equivalent series resistance ESR values. The two can be displayed with a decimal value , resolution 0.01 ohms

Can be in the correct order and the diode symbol display two diodes, and gives the diode forward voltage

 LED is detected as a diode forward voltage higher. Combo of the LED is identified as two diodes

Reverse breakdown voltage is less than 4.5V zener diode can be identified

 Can measure a single diode reverse capacitance. If the bipolar transistor connected to the base and collector or emitter of a pin, it can measure the collector or emitter junction reverse capacitance

 can be obtained with a single measurement rectifier bridge connection

Notice: Before measuring capacitance , the capacitor must be discharged , otherwise very likely damage the meter
