Small M8 12864 LCD MEGA328 Transistor Tester Capacitance ESR Meter Diode Triode MOS/PNP/NPN LCR Description: Transistors,field effect tubes,diodes,resistors,capacitors,inductors,etc. with the function of capacitor ESR test Power supply: DC9V (need to bring your own 9v layer-built battery 6F22) Weight: 0.077kg Use 12864 liquid crystal display with backlight,which color is green-black SMD,SMT technology, reflow soldering welding products (avoid suite welding leads to failure) Function: Graphical display pining symbols and pin order. Be clear at a glance Use 128 x 64 liquid crystal display (128 x 64 lattice points) Quick shutdown button Power consumption shutdown mode Boot voltage detection Automatic detection of NPN and PNP transistors, n-channel and p-channel MOSFET, diode (including double diode), thyristor, transistor, resistor and capacitor and other components Automatic test the pin of a component, and display on the LCD Can detect the transistor, MOSFET protect diode amplification coefficient and the determine to cardinal number and the emitter transistor forward biased voltage Measure the grid electrode threshold voltage and the MOSFET of gate capacitance High test speed, the validity of the component test in 2 seconds (except in large capacitor, which need a long time, the measured time is normal in 1 minute) A key operation, one-click fix the boot test Closed power consumption modes: less than 20nA Automatic shutdown function, which can avoid unnecessary waste, to save battery power, improve the battery life Notice: Before measuring capacitance,the capacitor must be discharged,otherwise very likely damage the meter Package included: 3 x Small Screen Version Transistor Tester
