• 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-100mF , 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. 

• Eeverse 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 ,Function:
