ITEM NAME:3.7V of inductor-capacitor ESR meter DIY MG328 multifunction transistor tester%a Feature： Brand new and high quality. Description: The main parameters and use: 1 using ATmega8, ATmega168 or ATmega328 microcontroller. 2 2x16 character LCD display results. 3 one-button operation, automatic power off. 4 shutdown current of 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 bipolar transistor, N, P-channel MOSFET, JFET, diodes, dual diode, thyristor SCR. 7 automatically detects the pin layout. 8 the threshold voltage and current amplification factor of the emitter junction of the bipolar transistor measurements. 9 Darlington transistor through a high threshold voltage and high-current amplification factor identified. 10 pairs of bipolar transistors, MOSFET protection diode testing. The threshold voltage value 11 and the gate capacitance of a MOSFET is measured. 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 may 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 can display symbols of the two diodes in the right direction.Range from 0: 01mH than 20H, but the accuracy is not good. Both ends of the resistor symbol is shown connected to the tester probes number (1-3). 6 Automatic detection PNP and NPN bipolar transistor, N, P-channel MOSFET, JFET, diodes, dual diode, thyristor SCR.
