Measuring bipolar transistor current amplification factor and base emitter threshold voltage
Via the basic emission 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 resistances and the resistance symbol is displayed. Displayed on the right with a decimal value of 4. Resistance symbol on both sides shows the PIN code. So you can measure the potentiometer. If the potentiometer wiper is not placed in an extreme position, we can distinguish the middle and both ends of the pen Resistance measurement resolution is 0.1 ohm, 50M ohm can be measured Can measure capacitance, can measure capacity of 30pF-100mF, resolution 1pF 2uF more capacitors can simultaneously measure the equivalent 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 shows two diodes and gives the diode a forward voltage. LED is detected when a diode-forward voltage is higher. Combination of the LED is identified as two diodes. Eeverse breakdown voltage is less than 4.5 V Zener diode can be identified Can measure a single diode reverse capacitance. If the bipolar transistor is connected to the base and the collector or emitter of a pin, it can measure the collector or emitter junction reverse capacitance. Can be obtained with a single bridge with rectifier bridges.
