DIY Kits M168 Transistor Tester Diode Triode Capacitance ESR Meter MOS PNP NPN Features : DiY kits, SMD components has been soldered, ,mega168 been programmed Features: Can measure the various diodes , transistors , MOS FET ; able to determine the device type , the polarity of the pins given HFE, the threshold voltage, the FET junction capacitance, can be measured capacitance and resistance, etc. Pin can be connect random,Screen gives corresponding test No of the pin Input voltage :9v Before Measuring capacitance , Must discharge fully, or will destory the tester 1,2013 latest version of the software ,more functions. 2,Use 8MHz external crystal , better measurement accuracy. 3.Backlight LCD display,only 2mA when stand by. 4,Using 9V battery. Specifications: 1,One -button operation, automatic shutdown . 2,Only 20nA shutdown current. 3,Automatically detect NPN, PNP bipolar transistors , N -channel and P -channel MOS FET, JFET , diodes , two diodes, thyristors small power unidirectional and bidirectional thyristor. 4,Automatic identification components pin arrangement . 5,Measuring bipolar transistor current amplification factor and base - emitter threshold voltage. 6,Via the base - emitter threshold voltage and high current amplification factor to identify Darlington transistors. 7,Can detect bipolar transistors and MOS transistors protection diodes. 8,Measuring the gate MOS FET threshold voltage and the gate capacitance. 9,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. 10,Resistance measurement resolution is 0.1 ohms , 50M ohms can be measured . 11,Can measure capacitanceCan measure capacitance of 30pF-100mF , resolution 1pF. 12.2uF more capacitors can simultaneously measure the equivalent series resistance ESR values. The two can be displayed with a decimal value , resolution 0.01 ohms. 13,Can be in the correct order and the diode symbol display two diodes , and gives the diode forward voltage. 14.LED is detected as a diode forward voltage higher . Combo of the LED is identified as two diodes. 15,Eeverse breakdown voltage is less than 4.5V Zener diode can be identified. 16,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 . 18 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 . Function: 1.Automatic recognition transistor type, pin, current magnification and the base - emitter junctionvoltage measured at the same time. 2. Automatic Identification of N and P MOSFET type and pin,measure the voltage and capacitance. 3.Automatic identification the diode pin, measurement the forward voltage. 4.Automatic identification of small power triac pin. 5.Measuring resistance. 6.Measuring inductance. 7.Measuring Capacitance.
