BSIDE ESR02 PRO Transistor Tester SMD Components Checker Mega328 NPN/PNP Diode Resistor Inductor Capacitance ESR Meter with Tweezers

[Wide Application]: It is very easy to test plug-in and SMD devices, it can also be used to test different kinds of triodes, thyristors, MOSFET, enable to analysis the device type, the polarity of the pin, the output HFE, the valve voltage, the junction capacitance of the FET. [Automatical Identification]: Intelligent transistor checker is able to detect NPN and PNP transistors, N-channel and P-channel MOSFET, diodes, thyristors, resistors, capacitors or other devices automatically. [Typical ESR Value Guide]: There is a table "typical ESR value of electrolytic capacitor" at the back, it is for guiding only, these are typical value for standard grade electrolytic capacitor at room temperature. [Easy to Use]: Our advanced electronic transistor tester owns auto shut-down function. Auto power off 20 seconds after measurement. Large LCD display with backlight function for easy reading. [Attention]: Be sure to discharge the capacitor before testing it, otherwise it may damage the internal circuit. It is powered by 1pcs of 9V 6LR61 battery, when the battery power is under 6V, please replace it with a new one. Choose DC 9V-12V adapter (including 9V and 12V) if using DC power supply.
