Description: 【Easy to use】The instrument is easy to use, just put the component into the test area and press the START button. 【Multipurpose】Start automatic measurement, can test, diode, triode, resistance, capacitance, inductance related parameters. 【Feature】Capacitor Resistor Detector Can measure, transistor, MOS tube, thyristor, Mosfet tube, IGBT (Note: High power thyristor, IGBT, may not be tested correctly)And can automatically identify the pin position (polarity) and can display related parameters in graphics (such as magnification, VBE and other parameters),Can test the code value of infrared remote control (only support NEC format) 【Size】Capacitor Resistor Detector is 3.15''x2.36''x0.79'' in size. 【Note】: Be sure to discharge the capacitor before testing it. Otherwise, the instrument will be directly damaged. This instrument is an active instrument. Do not use this instrument to measure live circuit boards. It will cause damage to circuit boards and instruments. Specification: 2 AAA battery(not included) Size Chart: 8cmx6cmx2cm/3.15inchx2.36inchx0.79inch Package Includes: 1 Transistor Tester Note: Please allow slightly errors due to manual measurement and different monitors.
