12864 LCD Mega328 Transistor Tester Capacitance ESR Meter Diode Triode MOS\/PNP LCR
Description:
Transistors，field effect tubes，diodes，resistors，capacitors，inductors，etc.with the function of capacitor ESR testPower supply: DC9V (need to bring your own 9v layer-built battery 6F22)Weight: 0.077kgUse 12864 liquid crystal display with backlight，which color is blue-whiteSMD，SMT technology， reflow soldering welding products (avoid suite welding leads to failure) Function: Graphical display pining symbols and pin order. Be clear at a glanceUse 128 x 64 liquid crystal display (128 x 64 lattice points)Quick shutdown buttonPower consumption shutdown modeBoot voltage detectionAutomatic detection of NPN and PNP transistors， n-channel and p-channel MOSFET， diode (including double diode)， thyristor， transistor， resistor and capacitor and other componentsAutomatic test the pin of a component， and display on the LCDCan detect the transistor， MOSFET protect diode amplification coefficient and the determine to cardinal number and the emitter transistor forward biased voltageMeasure the grid electrode threshold voltage and the MOSFET of gate capacitanceHigh 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 testClosed power consumption modes: less than 20nAAutomatic 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
Specifications: For you reference
1. Use ATmega8，ATmega168 or ATmega328 micro-controller2. 2 x16 character LCD display the results3. One key operation， automatically shut off the power4. Shut off the current only 20 nA， support for battery operation5. Low cost version without crystals， support automatically shut off the power. When there is no measurements， it will turn into sleep mode to reduce the power consumption for 1.05k version software ATmega168 or ATmega3286. Automatic detection of PNP and NPN bipolar transistor， N channel and P channel MOSFET，JEFT，diode，double diode，thyristor SCR7. Automatically detect pin layout8. Measuring current amplification coefficient of bipolar transistor and emitter junction of threshold voltage9. Darlington transistors can be identified by high threshold voltage and high current amplification factor10. The bipolar transistor and MOSFET protect diode detection11. Measuring the MOSFET threshold voltage and gate capacitance value12. Support two resistors measurement and symbolic display， which displayed that the top of four Numbers and units. According to the resistance of the symbol is connected on both ends of tester probe number (1-3). So the potentiometer also can be measured. If one end of the potentiometer to adjust to it， the tester is unable to distinguish the pins be
