    The use of SCM ATMEAG328P DIP-28. With IC Block
    The display unit using a 160x128 pixel color display, full-screen characters 8x20, 16-bit color depth, graphic display element symbols
    Rotary switch control, a key measurement, automatic shutdown
    Use 9V laminated battery, can also use the power adapter(DC 6.8-12V), the whole current of about 30mA, after about 20nA shutdown current
    Automatically detects NPN and PNP transistors, FET, diodes, dual diode, thyristor, SCR, automatic identification of the transistor pinout
    Test NPN and PNP transistor common-emitter current amplification factor, the base - emitter threshold voltage, off the collector - emitter leakage current
    Pole through the transistor base - emitter threshold voltage and high current gain recognition Darlington transistor
    Detecting power transistor and FET protection diodes built
    Test FET gate - source threshold voltage is turned on, the drain - source on-resistance, the gate - source capacitance
    A maximum of two measuring resistors, so three feet adjustable resistor can be measured, if adjustable resistor is transferred to the end, can only be a measured resistance value
    Resistance measurement maximum resolution 0.01Ω. Can be measured up to 50MΩ
    Capacitor measuring range from 25pF-100mF, Resolution 1pF
    Larger than 90nF capacitor while measuring its equivalent series resistance (ESR), the equivalent series resistance of the highest resolution of 0.01Ω
    Larger than 5000pF capacitor also showed the rate of decline after the charging voltage of the capacitor value can reflect the quality factor (Q value)
    Measuring a maximum of two diodes show its positive and negative, on-state voltage
    LEDs also display a graphic symbol diode, the conduction voltage is much higher than ordinary diode
    Reverse breakdown voltage is lower than 4.5V Zener diode can detect it, appears as double diode symbol. Its positive and negative voltage to turn around 700mV diode symbol prevail, a second diode symbol corresponding to the voltage is turned on regulation. So do not be an ordinary diode and a Zener diode were measured simultaneously
    Test a single diode, while its test reverse junction between the PN junction capacitance between the PN junction capacitance of the transistor to be tested, then only at the same time into the transistor base and the emitter, base and collector or
    Of less than 25pF capacitor to be tested, the test need to prepare a 30pF capacitor, 30pF capacitor to test, test and then measured again after the capacitor connected in parallel, by subtracting the measured value 30pF capacitors with the results obtained
    For the following 2100Ω resistor while measuring its inductance measuring range from 0.01mH - 20H
    About two seconds during the test, large capacitors and inductors will take longer
    Additional features include a frequency measurement, voltage measurement, square wave generator, PWM
    generator, color selection, commissioning calibration, continuous testing, and other functions
    Frequency range from 1Hz to 1MHz or higher, measured at frequencies below 25kHz, can display period resolution to 0.001mHz
    DC voltage measurement up to 50V
    All the way to the square wave signal output, multi-range frequencies to choose from, the maximum output frequency of 2MHz
    Output one fixed frequency, variable duty cycle pulse signal (PWM), the duty cycle is adjustable from 1% -99%
    Separate capacitive function test, the test mode for the continuous measurement of 2uF-50mF capacitors can be measured directly in their circuit (circuit where the measured capacitance required power, after the measured capacitance required to be fully discharged)
    Thyristors and thyristor can only recognize its pinout, and also need to test the thyristor or SCR trigger current is less than the current test instrument can provide, the tester can only provide a maximum trigger current 6mA
