ESR измеритель. Покупка на ебей. Распаковка. Обзор

Заказал себе тестер на ебей из китая. Заказал, так как он имеет возможность измерять ESR(ЭПС) конденсатора. Еще он может измерять сопротивление, проверять диоды, индуктивность, емкость конденсатора и другие параметры. Описание ниже: 1,2013 latest M328 version of the software ,more functions. 2,Use 8MHz external crystal , better measurement accuracy. 3.Back light LCD display,only 2mA when stand by. 4,Main chip is the DIP, easy to DIY, update the main chip . 5,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...
