ITEM NAME:M328 digital Transistor Tester Capacitance ESR Meter Diode Triode MOS LCR Product Description Description: 1. Using ATmega8, ATmega168 or ATmega328 microcontroller. 2. 2x16-character LCD display the results. 3. One button operation, auto power off. 4. Shutdown current is only 20nA, support for battery operation. 5. Low-cost version without the crystal, auto power off. 1.05k version of the software ATmega168 or ATmega328 in sleep mode when no measurement to reduce power consumption. 6. Automatic detection PNP and NPN type bipolar transistors, N, P-channel MOSFET, JFET, diode, a double diode, thyristor SCR. 7. Automatic detection pin layout. 8. Measuring current amplification factor of the bipolar transistor and the threshold voltage emitter junction. 9. Darlington transistor amplification factor can be identified by the high threshold voltage and high current. 10. For bipolar transistor, MOSFET protection diode testing. 11. Measuring the threshold voltage and the gate capacitance of the MOSFET. 12. Supports two resistance measurements and symbols show the highest four numbers and units. Both ends of the resistor symbol is shown connected to the tester probes number (1-3). Therefore, the potential can also be measured. If the potentiometer is adjusted to its end, the tester can not distinguish between the middle and the ends of the pin. 13. Resistance measurement resolution is 0.1 ohms, the highest measured value 50M ohms. 14. Can be detected and measured a capacitor. Maximum four numbers and units. Values can be from 25pf (8MHz clock, 50pF @ 1MHz clock) to 100mF. Resolution up to 1 pF (@ 8MHz clock). 15. Can be larger than the value for 2UF capacitor equivalent series resistance (ESR) measured capacitance value. Resolution of 0.01 ohms and a two-digit numeric display. This feature requires at least 16K Flash ATMEGA (ATmega168 or ATmega328). 16. Two diodes can display symbols in the right direction. In addition, the forward voltage drop displayed. 17. LED de.Twenty four. Both ends of the resistor symbol is shown connected to the tester probes number (1-3). Twenty three. Range from 0: 01mH than 20H, but the accuracy is not good. This will only happen if the diode is connected to all three probes and at least one diode.
