Features:The display unit using a 160x128 pixel color display, full-screen characters 8x20, 16-bit color depth, graphic display element symbolsRotary switch control, a key measurement, automatic shutdownUse 9V laminated b*attery, can also use the power adapter(DC 6.8-12V), the whole current of about 30mA, after about 20nA shutdown currentAutomatically detects NPN and PNP transistors, FET, diodes, dual diode, thyristor, SCR, automatic identification of the transistor pinoutTest NPN and PNP transistor common-emitter current amplification factor, the base - emitter threshold voltage, off the collector - emitter leakage currentPole through the transistor base - emitter threshold voltage and high current gain recognition Darlington transistorDetecting power transistor and FET protection diodes builtTest FET gate - source threshold voltage is turned on, the drain - source on-resistance, the gate - source capacitanceA 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 valueResistance measurement maximum resolution 0.01Ω. Can be measured up to 50MΩCapacitor measuring range from 25pF-100mF, Resolution 1pFLarger than 90nF capacitor while measuring its equivalent series resistance (ESR), the equivalent series resistance of the highest resolution of 0.01ΩLarger 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 voltageLEDs also display a graphic symbol diode, the conduction voltage is much higher than ordinary diodeReverse 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 simultaneouslyTest 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 orOf 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 obtainedFor the following 2100Ω resistor while measuring its inductance measuring range from 0.01mH - 20HAbout two seconds during the test, large capacitors and inductors will take longer1.
