ATmega328 microcontroller. 2.1284 LCD display results. 3. One button operation, automatic power off. 4. Shutdown current is only 20nA, support battery operation. 5. ATmega328 in sleep mode when there is 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. Automatic detection pin layout. 8. Current amplification factor measurement of the bipolar transistor and the threshold voltage emitter junction. 9. Darlington transistor may be identified by the amplification factor of the high threshold voltage and high current. 10. For bipolar transistor, MOSFET protection diode testing. 11. Measuring the threshold voltage of the MOSFET and the gate capacitance. 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 the two ends of the pin and the middle. 13. Resistance measurement resolution is 0.1 ohm, the highest measured value 50M ohms. 14. Can be detected and measured with a capacitor. Maximum four digits and units. Value can be from 25pf (8MHz clock, 50pF @ 1MHz clock) to 100mF. Resolution up to 1 pF (@ 8MHz clock). 15. For the above values can 2UF capacitor equivalent series resistance (ESR) capacitor value measurements. Resolution of 0.01 ohms and a two-digit numeric display. 16. Two diodes can display symbols in the right direction. Further, the display forward voltage drop. 17. LED detection diode forward voltage drop is much higher than normal. Dual LED detected as double diodes. 18. Zener diode can be detected if the reverse breakdown voltage is less than 4.5V. This is displayed as two diodes, can only be determined by the voltage. Diode symbol is the same around the probe, in this case you can 700mV threshold voltage near real identification diode anode! 19 If more than three diode-type parts detection, failure to establish the number of diodes another message. This will only happen if the diode is connected to all three probes and at least one diode. In this case, you should only connect the two measuring probe and start again, one by one. 20. Measuring a single diode reverse capacitance value. Bipolar transistors also can measure, if you connect the base and collector or emitter. Twenty one. Only one measurement to find full-bridge connection. Twenty two. Values less than 25pf capacitor typically undetectable, but a diode in parallel with 25pf capacitor or at least parallel. In this case, you must subtract the part of the parallel capacitance values. Twenty three. Less than 2100 ohm resistor will measure inductance, if you have at least 16K ATMEGA flash. Range from 0:01 mH than 20H, but the accuracy is not good. Measurement results show only a single component connection. Twenty four. Testing time is about two seconds, only capacitance and inductance measurements will take a long time. 25. Software can set the number of measurements before the power is automatically turned off. 26. Built-in self-test function with selectable clock frequency of 50Hz signal to check the accuracy and waits for a call (ATmega168 and ATmega328). 27. Optional internal resistance and zero offset calibration of measuring equipment self-test capability of the output port (ATmega168 and ATmega328). Need a 100nF to 20uF capacitor connected to the compensation between analog comparator pins 1 and 3 of the offset voltage. This can reduce the measurement error than 40uF capacitor. With the same internal calibration capacitor voltage internal reference voltage is found to adjust the reference measurement ADC gain. If the test current exceeds the holding current, SCR and triac can be detected. But some current higher than the semiconductor SCR and triac tester can provide the trigger current. Available test current is only about 6mA!
